Testo completoAbstract (sommario):
Poultry is susceptible to mycotoxicoses caused by aflatoxins. Two experiments were carried out, where twenty-four, 28days old and 144 one-day-old broilers were assigned to six diets respectively. The diets were: diet1 (no aflatoxin and not fermented), diet2 (no aflatoxin and fermented without yeast), diet3 (no aflatoxin and fermented with yeast), diet4 (contained aflatoxin and not fermented), diet5 (contained aflatoxin and fermented without yeast) and diet6 (contained aflatoxin fermented with yeast). The aflatoxins were 20.034 and 30.08ppb for the first and second experiments respectively. In the first experiment, each diet was assigned to 4 chickens for 7days adaptation and 7days for feces and leftover collection. The feces were oven dried for the determination of dry matter digestibility (DMD), metabolizable energy (ME) and nitrogen (MN). In the second experiment, each diet was assigned to six chicks, replicated 4 times for 21days. Leftovers and mortalities were recorded daily and chicks were weighed on a weekly basis. The results showed that DMD and MN were significantly (p<0.05) affected by fermentation. Natural fermentation improved DMD of the clean and contaminated diets. No difference found in feed intake and body weight gain. However, gain: feed ratio was significantly (p=0.048) better in broilers fed diets fermented naturally. The mortality rate was 75.0% in chicks fed on aflatoxin diet which was not fermented. Therefore, natural fermentation is the best method of improving the quality of aflatoxin contaminated feed for broilers.

Testo completoAbstract (sommario):
Two studies were conducted to evaluate the effects of diet on phosphorus (P) digestion in dairy cattle. The objective of the first study was to evaluate the effects of forage and non-fiber carbohydrate (NFC) content on total P (TP) and inositol phosphates-P (IPs-P) digestion. Samples of feed, duodenal digesta and feces from a previously conducted study were analyzed for TP and IPs-P. In this study, eight lactating Holstein cows were fed diets containing either 60 or 35% forage and either 30 or 40% NFC in a 2 × 2 factorial with replicated 4 × 4 Latin square design. Dietary TP content (% DM) was 0.35, 0.36, 0.36, 0.36 and dietary IPs-P content (%DM) was 0.08, 0.13, 0.06, 0.11 for diets with forage: NFC ratio 35:30, 35:40, 60:30, and 60:40, respectively. Increasing dietary forage content decreased IPs-P and TP intake, fecal TP excretion, and total tract IPs-P digestibility (72.4 vs. 61.4%). Fecal IPs-P excretion tended to decrease as increasing forage content. Duodenal IPs-P and TP flow and apparent TP digestibility were unaffected by forage content. Increasing dietary NFC content increased IPs-P and TP intake, duodenal IPs-P flow, fecal IPs-P excretion, total tract IPs-P digestibility (61.4 vs. 72.4%), and apparent TP digestibility (32.8 vs. 41.6%). Dietary forage and NFC content affected IPs-P and TP digestion. The second study was to evaluate the effects of increasing dietary beet pulp (BP) content to replace high moisture corn (HMC) on ruminal and post-ruminal digestion of TP and IPs-P. Eight lactating Holstein cows were fed diets containing 0, 6.1, 12.1 or 24.3% BP in a replicated 4 × 4 Latin square design. Samples of rumen contents, duodenal digesta, and feces from this previously conducted study were analyzed for TP and IPs-P content. Linear and quadratic effects of BP content were analyzed using Proc Mixed of SAS. Dietary TP and IPs-P content were reduced linearly with increasing BP (0.59, 0.58, 0.57, 0.56% TP and 0.15, 0.14, 0.13, 0.11% IPs-P). Intake, ruminal content, and rumen pool size of TP decreased with increasing BP content. Digestion of TP and duodenal flow and fecal excretion of IPs-P and TP were not affected. With increasing dietary BP content, IPs-P intake was reduced, ruminal IPs-P pool size was reduced, and rumen turnover time (h) of IPs-P was increased. Apparent ruminal IPs-P digestibility (36.5, 31.8, 24.6, 13.6 %) and apparent total tract IPs-P digestibility (85.3, 82.7, 82.1, 79.1%) decreased linearly with increasing BP. Fecal excretion of IPs-P averaged 5.2 g/d. Replacing HMC with BP reduced digestion of IPs-P. The majority of IPs-P disappearance occurred post-ruminally. In conclusion, dietary BP, forage, and NFC content affected IPs-P digestion in dairy cows.Master of Science

Testo completoAbstract (sommario):
The beet armyworm, Spodoptera exigua, has evolved numerous mechanisms to circumvent plant defense responses. One of these mechanisms is believed to involve the activity of labial salivary glucose oxidase (GOX) which, through the production of hydrogen peroxide, interferes with plant induced defenses. The activity of GOX is diet-dependent. The expression of SeGox and another salivary gene, Se1H, are differentially regulated in response to diet (plant or transfer from plant to wheat-germ based artificial diet for 4 hours), but not in response to chemically defined artificial diets varying in protein to digestible carbohydrate ratios. However, GOX enzyme activity is dependent on the nutrient quality of the chemically defined artificial diets. This suggests that nutritional quality controls enzyme activity through post-transcriptional regulation. To simulate natural plant diets, Medicago truncatula plants were grown under ambient (440 ppm) or elevated (880 ppm) carbon dioxide conditions to alter their C:N ratio. When caterpillars were fed these plants, labial salivary GOX activity was undetectable regardless of the plant treatment. Finally, 5' upstream regions of salivary genes Se1H, Se2J and SeGox were amplified to determine potential upstream promoter elements, but were unable to be sequenced due to amplicon contamination.La chenille de Spodoptera exigua est capable de nourrir sur les plantes malgré ses défenses anti-herbivores, grâce à des enzymes salivaires. Un de ces enzymes salivaires capable de combattre les defenses, glucose oxidase (GOX), est aussi régulé par la diète avec laquelle la chenille se nourrit. Il est donc important d'identifier la réglementation des produits salivaires comme GOX. Ce projet vise à déterminer les tendances de transcription et d'activité enzymatique de trois gènes salivaires (Se1H, Se2J et SeGox) en réponse de différentes diètes. De plus, les régions en amont des gènes salivaires ont tentées être séquencer afin de trouver des promoteurs putatives. Les résultats ont démontré que les trois gènes ne sont pas régulées transcriptionellement, mais que l'activité enzymatique de GOX dépend de la qualité nutritive des diètes. Cependant, les régions en amont des trois gènes n'ont pas pu être séquencé à cause de raisons de contaminations et d'amplification imprécises.

Testo completoAbstract (sommario):
This dissertation serves as a report on the qualitative exploration of best practices in animal-assisted therapy (AAT) with children. The aim of the study was to explore and describe best practices in the field of AAT with children in the Western Cape. The research made use of the case study design, which offered the researcher the opportunity to interact with a small number of individuals and look for patterns in the research participants’ words and experiences. Four participants, who were trained mental health professionals and had offered AAT to children, were selected to participate in the research.
A literature review of animal-assisted therapy and best practice provided a theoretical basis for the research. The history of AAT, the uses and benefits of AAT and the animals incorporated in AAT were explored. The term “best practice” and its application in mental health and AAT were also discussed.
The verbatim transcriptions of the audiotaped data were analysed and interpreted using Interpretative Phenomenological Analysis (IPA) and an AAT conceptual framework (brought about by the literature review). Themes were developed from the empirical data and substantiated by the literature review. Five main themes emerged as a result of the analysis. The first theme, Training of the animal-assisted therapist, focused on both the mental health training and the AAT training of the therapist. The second theme, Training of animals incorporated in animal-assisted therapy, revealed the importance of training the animal to be included in AAT. The third theme, Different client populations in animal-assisted therapy, looked at which populations should be included, excluded or included and carefully managed during AAT. The fourth theme, Ethical considerations in animal-assisted therapy, revealed the importance of considering both the child’s and the animal’s welfare. The fifth theme, Regulation of animal-assisted therapy, gave a more in-depth description of the current regulation of AAT in the Western Cape and provided suggestions for the regulation of AAT. Based on the findings of the five themes, recommendations were made for best practice in AAT with children in the Western Cape.Thesis (MA (Psychology))--North-West University, Potchefstroom Campus, 2013.

Testo completoAbstract (sommario):
The nutritional value of molassed sugar beet feed as a dietary component was assessed in a series of three experiments. In experiment 1, the effect of molassed sugar beet feed pellets (32 or 64 g/kg fresh weight silage) either ensiled or fed separately with big-bale silage on silage quality and performance of male castrate sheep (initial liveweight 29 kg) was studied. On average, the inclusion of molassed sugar beet feed increased silage dry matter, water soluble carbohydrate and lactic acid concentrations and decreased silage ammonia concentrations. Molassed sugar beet feed either ensiled or given as a supplement, significantly improved total dry matter intakes and liveweight gain (P< 0.05) and metabolisable energy intakes (P< 0.01) in lambs. Experiment 2 was carried out to investigate the effects of feeding two levels of fishmeal in addition to molassed sugar beet feed as supplements to big-bale grass silage fed ad libitum to beef steers of 290 kg initial liveweight. Bale silage was given alone or supplemented with 800 g molassed sugar beet feed/day, molassed sugar beet feed + 125 g fish meal/day or molassed sugar beet feed + 250 g fish meal/day. Supplementation of big-bale silage with molassed sugar beet feed did not increase total dry matter intake or improve liveweight gain. Adding FM to a diet composed of big-bale silage and molassed sugar beet feed significantly increased liveweight gain, total ruminal volatile fatty acid and ammonia concentrations. The effect of diets differing in the ratio of molassed sugar beet feed to barley and the inclusion of yeast culture on growth and rumen metabolism of sheep (initial liveweight 36 kg) was examined in experiment 3. Four diets, which were offered ad libitum , consisted of pelleted or molassed sugar beet feed, barley and soya-bean meal in the following proportions (DM basis) either A, 770:170:60 or B, 470:470:60. Diets A and B were fed with and without 2 g Yea-Sacc/head/day.

Testo completoAbstract (sommario):
The concept of inter-country adoptions was reintroduced into the South African legal sphere in The Minister of Social Welfare and Population Development v Fitzpatrick 2000 3 SA 422 (CC), where the constitutionality of section 18(4)(f) of the Child Care Act 74 of 1983, which prohibited inter-country adoptions, was successfully challenged. The decision evoked criticism from all around the world, some in favour of inter-country adoptions and others not.
In considering this decision, one also has to keep in mind section 28(1)(b) of the Constitution of the Republic of South Africa, 1996 which affords every child the right to family care or parental care, or to appropriate alternative care when removed from the family environment.
The aim of this paper is to investigate the inner workings of inter-country adoptions, which are regulated by the Hague Convention on Protection of Children and Co-operation in Respect of Intercountry Adoption of 1993 and, nationally, the Children’s Act 38 of 2005. These findings will then be relayed back to the ‘best interests of the child’ principle to determine whether inter-country adoption is in the best interests of the child, or not.Thesis (LLM (Comparative Child Law))--North-West University, Potchefstroom Campus, 2013.

Testo completoAbstract (sommario):
La ligne de Petite Ceinture de Paris est un ancien chemin de fer à double voie de 32 kilomètres de longueur (hors raccordements) qui faisait le tour de Paris à l’intérieur des boulevards des Maréchaux. Ouverte par tronçons de 1852 à 1869, elle est d’abord exclusivement consacrée au trafic de marchandises avant d’être ouverte au trafic de voyageurs, à l’exception de la ligne d’Auteuil, à l’inverse directement ouverte aux voyageurs en 1854 et seulement en 1867 pour les marchandises. Désertée par les Parisiens en raison de la concurrence croissante du métropolitain à partir de 1900, la ligne est, pour l’essentiel de son parcours, fermée au trafic de voyageurs le dimanche 22 juillet 1934, hormis la ligne d’Auteuil, restée ouverte jusqu’en 1985. Le trafic de marchandises a également disparu depuis le début des années 1990, et la ligne est aujourd’hui en grande partie abandonnée et amputée d’une partie de sa longueur. Une portion de la ligne d’Auteuil a toutefois été intégrée en 1988 à la ligne C du RER. De nombreuses gares ont été détruites dont Montsouris. La gare de Passy a été conservée en étant transformée en restaurant. Des gares ont été converties comme la gare de Charonne. Restée à l’abandon depuis 1993, la Petite Ceinture a fait l’objet d’une première phase de concertation en 2013 afin d’en esquisser l’avenir. Notre travail de recherche s’inscrit au coeur de ce débat du devenir de la Petite Ceinture de Paris. Il vise à démontrer l’importance de cette emprise ferroviaire depuis sa création en 1852 jusqu’à sa fermeture en 1934 pour le service de voyageurs. Nous proposons une analyse comparative de la situation de la gestion comptable et financière depuis 1854 à 1934 pour déterminer les différents résultats d’exploitation réalisés afin d’évaluer la performance financière de la ligne. Notre démarche consiste à comprendre pourquoi des hommes intelligents, en possession de tous leurs moyens, ont-ils pu prendre la décision d’interrompre volontairement l’activité de la ligne Petite Ceinture. Quels sont les conséquences de la mise en jachère de très long terme de cette plate-forme ferroviaire ? Quels sont les manques à gagner de cette mise en sommeil ? Peu de recherches se sont basées sur cette démarche, et notre travail de recherche était d’étudier les différentes approches de la décision fondées sur les théories de la décision rationnelle de Simon, de Cyert et de March et sur les théories de la décision absurde de Christian Morel. Après confrontation de ces différentes approches, nous avons tiré comme résultat pour échapper à la non décision, l’application de la théorie de la métarègle de la fiabilitéThe Line Little Belt is a former Paris railway line double track 32 kilometers in length (excluding connections) who went around Paris within the boulevards of the Marshals. Opened by sections 1852 to 1869, it is first devoted exclusively to freight traffic before being opened for passenger traffic, with the exception of the Auteuil line, unlike directly open to travelers in 1854 and only in 1867 for goods. Deserted by Parisians because of growing competition from the Metropolitan in 1900, the line is, for most of his career, closed to passenger traffic Sunday, July 22, 1934, except the Auteuil line remained open until in 1985. Freight traffic has disappeared since the early 1990s, and the line is now largely abandoned and missing a portion of its length. A portion of the Auteuil line, however, was built in 1988 to the RER C line. Many stations were destroyed including Montsouris. Passy Station has been preserved by being converted into a restaurant. Stations were converted as station Charonne. Remained abandoned since 1993, the Little Belt has been the subject of a first phase of consultation in 2013 in order to sketch the future. Our research is at the heart of the debate about the future of the Little Belt Paris. It aims to demonstrate the importance of the railway line since its inception in 1852 until it closed in 1934 for passenger service. We provide a comparative analysis of the situation of the accounting and financial management from 1854 to 1934 to determine the different results of operations conducted to evaluate the financial performance of the line. Our approach is to understand why intelligent men, in possession of all their resources, they have taken the decision to voluntarily stop the activity of theLittle Belt line. What are the consequences of setting aside of the very long term of this railway platform? What are theshortfalls of this Sleep? Little research has been based on this approach, and our research was to study the differentapproaches to the decision based on the theories of rational decision of Simon of Cyert and March and the absurd theories of decision Christian More l . After comparison of these different approaches, we have learned as a result to escape the non-decision, applying the theory of meta-rule of the reliability

En la presente Tesis Doctoral se utilizaron cebada y remolacha como fuentes alternativas de carbohidratos en dietas para trucha arcoíris con el objetivo de evaluar su efecto sobre parámetros productivos, histología hepática e intestinal, estrés y calidad de la carne.
Los marcadores estudiados fueron los mismo tanto para los experimentos de cebada como de remolacha. En las pruebas de la cebada se utilizaron concentraciones crecientes de este ingrediente (0-32%) en la dieta, se inició con un peso medio de 127.72 ± 5.65 g y se finalizó cuando alcanzaron el peso comercial al cabo de 84 días. En las pruebas de remolacha se utilizaron dos niveles de remolacha (14% y 28%) y dos de betaína (0.9% y 1.63%), se inició con un peso medio de 69 ± 2.2 g y se finalizó cuando los peces alcanzaron el peso comercial al cabo de 105 días.
La inclusión de cebada en dietas de trucha arcoíris no mostró diferencias significativas en los parámetros de crecimiento ni biométricos. La inclusión de 14% remolacha y 0.9% betaína no afectó al crecimiento, parámetros nutritivos, biométricos y retenciones de nutrientes en comparación con el control, concentraciones mayores de remolacha y betaína tuvieron un efecto negativo.
Cuando se estudiaron los parámetros histológicos y morfométricos en hígado e intestino, los resultados mostraron que los peces alimentados con concentraciones crecientes de cebada mostraron hepatocitos más pequeños, mientras que los peces alimentados con remolacha y betaína presentaban hepatocitos más grandes, en ambos casos el hígado mostró un menor nivel de vacuolización. La concentración de cebada de un 8% produjo un efecto negativo a nivel morfológico del intestino, sin embargo, la inclusión de remolacha no produjo ningún efecto.
Los peces fueron sometidos a estrés por ausencia de oxígeno y aumento de densidad durante 10 minutos. Cuando el estrés fue analizado a nivel bioquímico los resultados mostraron que a niveles basales, la inclusión de cebada y remolacha no causó ningún cambio en los niveles de cortisol, glucosa y MDA, aunque los valores basales de lactato fueron significativamente más bajos en los peces alimentados con remolacha y betaína. Treinta minutos después del estrés la concentración de cortisol, glucosa y lactato aumentó significativamente en los peces de todos los grupos y la concentración de MDA disminuyó. La inclusión de cebada mostró valores más bajos de cortisol, glucosa y lactato que la dieta control.
Cuando los peces alcanzaron el peso comercial se analizó la calidad de los filetes y las propiedades antioxidantes. En ambas pruebas los peces alimentados con los ingredientes objeto de estudio mostraron valores de actividad de agua más bajos y una mejora en la textura y el color de los filetes comparado con los peces alimentados con la dieta control. La inclusión de remolacha y betaína no tuvo ningún efecto sobre los parámetros oxidativos del filete, mientras que la inclusión de cebada inhibió su oxidación lipídica. Concentraciones de cebada por encima del 8% mejoraron la actividad antioxidante de los filetes y aumentaron el contenido en alpha-tocoferol, sin embargo, los peces alimentados con remolacha y betaína mostraron un mayor contenido en flavonoides y fenólico pero no se observó ningún efecto sobre las propiedades antioxidantes del filete.
Por último, cuando se llevó a cabo el análisis sensorial se observó que los peces alimentados con dietas con más de un 8% de cebada mostraron unas agallas más rojas y mejor textura, además de un color rojo del filete más intenso, parámetros que se correlacionan con una mejora de la frescura del pescado. Sin embargo, la inclusión de cebada o remolacha en dietas de trucha arco iris no tuvo ningún efecto sobre la aceptabilidad de los filetes.The current Doctoral Thesis used barley and red beet as alternative carbohydrate sources in rainbow trout diets. The aim was to evaluate their effect on productive, histological and morphometric parameters, their effect on biochemical indexes after an acute stress and their effect on the quality of rainbow trout (Oncorhynchus mykiss). The different markers studied were the same in the barley and red beet experiments. In the barley experiment, increasing concentrations of barley (0-32%) were used in the diet, starting with an average weight of 127.72 ± 5.65 g and ending when they reached commercial weight after 84 days. In the red beet experiment, two red beet levels (14% and 28%) and two betaine levels (0.9% and 1.63%) were used, starting with an average weight of 69 ± 2.2 g and finishing when they reached commercial weight at the end of 105 days. The inclusion of barley in rainbow trout diets did not show significant differences in growth and biometric parameters. While the inclusion of 14% of red beet and 0.9% betaine did not affect growth, nutritive or biometric parameters and nutrient retentions compared to control, higher red beet and betaine concentrations showed a negative effect. When the histological and morphometric parameters were studied in liver and intestine, the results showed that fish fed at high barley concentrations showed smaller hepatocytes than control, while hepatocytes were larger in fish fed with red beet and betaine than control, however, in both cases, the liver had a lower level of vacuolization. Barley inclusion at 8% produced a negative effect at intestine morphological level; however, no effects were observed with the inclusion of red beet. Fish were submitted to stress, a lack of oxygen and increased of fish density, during 10 minutes. The results showed that at basal levels, the inclusion of barley and red beet did not cause any change in cortisol, glucose and MDA levels, although basal lactate values were significantly lower in the fish fed with red beet and betaine. Thirty minutes after stress the concentration of cortisol, glucose and lactate increased significantly in the fish of all groups and the concentration of MDA decreased. The inclusion of barley showed lower cortisol, glucose and lactate values than control. When fish reached commercial weight, the quality of the fillets and antioxidant properties were analysed. In both trials, fish fed with the experimental ingredients showed lower water activity values and textural and colour properties were enhanced. Red beet and betaine inclusion did not show any effect on the oxidative parameters of the fillets, while the inclusion of barley showed an inhibitory effect on fillets lipid oxidation. Concentrations of barley above 8% improved the antioxidant activity of the fillets and increased the content of alpha-tocopherol, however, fish fed with red beet and betaine showed a higher content of flavonoids and phenolics but no effect on the antioxidant properties of the fillet. Finally, when the sensory analysis was carried out, it was observed that fish fed diets with more than 8% barley showed redder gills and better texture than control, in addition to a more intense red colour of the fillet, these characteristics are correlated with an improvement of fish freshness. However, the inclusion of barley or red beet in rainbow trout diets had no effect on the acceptability of fillets.

La inclusió d'ordi en dietes de truita no va mostrar diferències significatives en els paràmetres de creixement i biomètrics. La inclusió de 14% remolatxa i 0,9% betaïna no va afectar el creixement, paràmetres nutritius, biomètrics i retencions de nutrients en comparació amb el control, concentracions majors de remolatxa i betaïna van tenir un efecte negatiu. Quan es van estudiar els paràmetres histològics i morfomètrics en fetge i intestí, els resultats van mostrar que els peixos alimentats amb concentracions creixents d'ordi tenien hepatòcits més petits, mentres que els peixos alimentats amb remolatxa i betaïna presentaven hepatòcits més grans, i en ambdós casos el fetge va mostrar un menor nivell de vacuolització. La concentracion d'ordi d'un 8% va produir un efecte negatiu a nivell morfològic de l'intestí, mentres que la inclusió de remolatxa no va produir cap efecte a nivell d'intestí. Els peixos van ser sotmesos a estrès per absència d'oxigen i augment de densitat durant 10 minuts. Quan l'estrès va ser analitzat a nivell bioquímic els resultats van mostrar que a nivells basals, la inclusió d'ordi i remolatxa no va causar cap canvi en els nivells de cortisol, glucosa i MDA, encara que els valors basals de lactat van ser significativament més baixos en els peixos alimentats amb remolatxa i betaïna. 30 minuts després de l'estrès la concentració de cortisol, glucosa i lactat va augmentar significativament en els peixos de tots els grups i la concentració de MDA va disminuir. La inclusió d`ordi va mostrar valors més baixos de cortisol, glucosa i lactat que la dieta control. Quan els peixos van aconseguir el pes comercial es va analitzar la qualitat dels filets i propietats antioxidants. En ambdues proves els peixos alimentats amb els ingredients objecte d'estudi van mostrar valors d'activitat d'aigua més baixos i una millora en la textura i el color dels filets comparat amb els peixos alimentats amb la dieta control. La inclusió de remolatxa i betaïna no va tenir cap efecte sobre els paràmetres oxidatius del filet, mentre que la inclusió d'ordi va inhibir l'oxidació lipídica dels filets. Concentracions d'ordi per sobre del 8% van millorar l'activitat antioxidant dels filets i van augmentar el contingut en alpha-tocoferol, però, els peixos alimentats amb remolatxa i betaïna van mostrar un major contingut en flavonoides i fenòlic però no es va observar cap efecte sobre les propietats antioxidants del filet. Finalment, quan es va dur a terme l'anàlisi sensorial es va observar que els peixos alimentats amb dietes amb més d'un 8% d'ordi van mostrar unes ganyes més vermelles i millor textura, a més d'un color vermell del filet més intens, paràmetres que es correlacionen amb una millora de la frescor del peix. No obstant això, la inclusió d'ordi o remolatxa en dietes de truita no va tenir cap efecte sobre l'acceptabilitat dels filets.

AbstractThis chapter explains how and why economics is useful for studying agriculture and food systems. All human populations have profound similarities in our nutritional needs, but people everywhere live under vastly different conditions. The economics of agriculture, food and nutrition offers powerful insights into how and why people respond to their unique circumstances in different ways. Economics offers a toolkit of methods and data developed over centuries of studying how people escaped hunger and undernutrition, and now need to address climate change, the global rise of diet-related diseases and other obstacles to further progress. This book is intended to be a core text for students in courses taking an economics perspective on food policy, agricultural development, food systems, or nutrition and health. No previous training is needed beyond secondary school algebra and geometry. Some students will come at this topic from the humanities and social sciences, while others will have studied agriculture or the health sciences, but everyone can use economics to understand how individual decisions and societal interactions drive the outcomes we observe, and how evidence-based policies and interventions can best improve agriculture, food and health.

Dave Schläpfer befasst sich in diesem Beitrag mit dem Phänomen, dass mit dem Aufkommen von Covid-19 die Reaktivierung alter Wissensbestände einhergeht - so war länderübergreifend plötzlich wieder markant häufiger von »Typhoid Mary« die Rede. Auch die Stunde alternativer Bands schlug: Zeitnah entstanden Erzeugnisse, die auf den historischen Fall der »Typhoid Mary« - der Übername für eine selbst immune Typhus-Überträgerin im New York des frühen 20. Jahrhunderts - oder andere damit stärker oder schwächer zusammenhängende Kontexte referieren und diese Elemente teils konkret mit Corona verknüpfen. Mit der Materialisation als Songs werden die Erzählungen im Feld von Pandemie und Ansteckung körperlich unmittelbar fühl- und erfahrbar.

Testo completoAbstract (sommario):
Beyond meeting nutritional requirements for growth and maintenance, select dietary ingredients can have additional effects, intended or not, on animal physiology and immune function. Diets can be enriched to benefit the animal, and a dual benefit can be achieved in the case of enriching animal products for the downstream human consumer. Many immune-altering nutrients are fat-soluble, including Vitamin E and D. Importantly, dietary lipids themselves can impact immune function; therefore, a focused and intentional selection of specific dietary fats, specifically omega-3 polyunsaturated fatty acids (PUFA), is one method to alter inflammatory cascades in animals consuming the diet. Examples of other related ingredients to which the immune system is responsive include zinc and probiotics. While work in human, livestock, and companion animal models is working to identify therapeutic inclusion rates for these nutrients and ingredients, it should be noted that physiological alterations are seen in both over and under-inclusion and are nutrient-specific. For example, inclusion above currently recommended levels may optimize immune function and reduce inflammation in the case of vitamin D or omega-3 PUFA, while for zinc, additional pharmacological supplementation above requirements may inhibit immune function. Importantly, when a diet is formulated to reduce overall systemic inflammation, it must be considered that important “background†functions of the immune system, including monitoring for and clearing pathogenic microbial populations, may be down-regulated due to a general reduction in immune reactivity. Continued work to understand how diet and nutrition impact immunity, and how to balance inflammation through nutrition, is an area of active research and will inform downstream users how to best use data to impact consumers of that feed in desirable ways.

Testo completoAbstract (sommario):
Introduction: Multiple sclerosis (MS) is a neurodegenerative autoimmune disease of the central nervous system with a chronic, progressive and inflammatory character. In addition, it presents itself in a heterogeneous way, and can be as an isolated syndrome or as a recurrent remitter, in the first stage, or as progressive, in the second stage. The present work was developed with the objective of determining which is the best form of diagnosis and therapy for multiple sclerosis in Brazil. Methods: The review was performed in PubMed platform, with the descriptors: “multiple sclerosis”, “diagnosis”, “therapy” and “research”. Results: The research result in 148 articles. After a criterious reading and the application of the used criteria, was selected 20 articles. Conclusion: For the diagnosis of this chronic neurological disease, magnetic resonance imaging is used to assess myelination of the different regions of the central nervous system, which is the most suitable for the diagnosis of MS. Μoreover, as a complement, cerebrospinal fluid extraction and blood tests are performed in order to ascertain the concentration of B cells. Regarding therapeutics, this is diversified, including drugs, diets and therapies that stimulate cognition and motor action, such as the use of virtual reality programs and motor images. In relation to drugs, it is of importance that SUS makes natalizumab and ocrelizumab available because they are more efficient and enable users to have a better quality of life. Finally, nutritional monitoring is also suggested to establish a ketogenic or fasting diet in a balanced way

Testo completoAbstract (sommario):
High blood pressure is a leading cause of premature death. Healthy lifestyle choices (of diet, exercise, sleep and stress) could offer significant results. However, health literacy and - competence are lacking in most people, compared to best practice health choices, so there is room for improvement in creating hypertension self-management results. We tested an intensive two-week Self-Management Support (SMS) pilot, using daily feedback and microlearning cycles. Participants (n=8) reduced their blood pressure from 145/92 to 126/86 mmHg on average. User evaluation on effectiveness of the health support elements highlighted the importance of key SMS components like: information transfer, daily monitoring, enhancing problem solving/decision making, self-treatment using a tailored action plan, coping skills and ongoing follow-up with skilled coaches. Moreover, several aspects from microlearning, peer coaching, results-achievement and feeling better (=intrinsic motivation) were useful and hold promise for future intervention updates.

Testo completoAbstract (sommario):
Diverticulosis occurs when small, bulging pouches (diverticula) develop in your digestive tract. When one or more of these pouches become inflamed or infected, the condition is called diverticulitis. Diverticula are small, bulging pouches that can form in the lining of your digestive system, although it was rare before the 20th century, diverticular disease is now one of the most common health problems in the western world. It’s a group of conditions that can affect your digestive tract. The most serious type of diverticular disease is diverticulitis. It can cause uncomfortable symptoms and, in some cases, serious complications. If left untreated, these complications can cause long-term health problems. Read on to learn more about diverticulitis, including its causes, symptoms, treatment options, and how your diet might affect your risk of developing it. Objective: In this paper, our main focus was on diverticulitis and surgical intervention, and only relevant studies were discussed. Methodology: PubMed database was used for articles selection, and papers on diverticulitis were obtained and reviewed. Conclusion: Colonoscopy is best avoided in acute and uncomplicated diverticulitis. Classically, it is a surgical disease but uncomplicated cases can often be managed conservatively. Follow up of treated diverticulitis occurs after four weeks via colonoscopy, in selected cases assessing the risk of developing colonic cancer. Novel therapies are under-studied and are probable replacements for surgical intervention.

Testo completoAbstract (sommario):
In Deutschland und Europa versuchen Verkehrsunternehmen und -verbünde bereits seit längerer Zeit gegen das Fahren ohne (gültigen) Fahrschein vorzugehen, ihre Fahrgeldeinnahmen zu sichern und zu steigern sowie die Quote der Personen, die den ÖPNV ohne (gültiges) Ticket nutzen, zu minimieren. Auf Grundlage des ersten Arbeitspaketes (Literaturanalyse zum Stand der Forschung: Schwerdtfeger et al. 2016) wurden Maßnahmen untersucht, die zum Erreichen der genannten Ziele beitragen. Der Fokus liegt dabei auf Best Practice Beispielen, also Maßnahmen, die in der Praxis als erfolgreich hinsichtlich der Reduzierung des Fahrens ohne (gültigen) Fahrschein sowie hinsichtlich der Einnahmesicherung und -steigerung angesehen werden. Das Ergebnis der Untersuchung ist eine umfangreiche Auseinandersetzung mit Best Practice Beispielen in Bezug auf das Fahren ohne (gültigen) Fahrschein. Außerdem wurden aktuell diskutierte Ansätze alternativer Finanzierungsinstrumente hinsichtlich ihrer Eignung zur Finanzierung des ÖPNV untersucht. Zwar können alternative Finanzierungsinstrumente derzeit noch nicht als Best Practice eingestuft werden, allerdings stehen sie in direkter Beziehung zur Einnahmesicherung im ÖPNV-Sektor.

Testo completoAbstract (sommario):
Menschenzentrierte Arbeitsprozessmodellierung - Kommunikationsmedium für Veränderungen von Mensch-Maschine-Interaktionen im Zuge der Implementierung von KI Im Rahmen dieses Working Papers wird eine Modellierungstechnik für Mensch-Maschine-Interaktionen vorgestellt, welche eine menschenzentrierte Arbeitsprozessgestaltung erlaubt. Diese Form der Modellierung basiert auf der semantischen Objektmodellierung nach Ferstl & Sinz und ermöglicht eine Prozessdarstellung mit Fokus auf den Interaktionen zwischen menschlichen und maschinellen Aufgabenträgern. Die Interaktionen werden dabei durch Informationen wie dem Automatisierungsgrad und der Art der Aufgabendurchführung spezifiziert, um das Verständnis über die Ausprägung der Interaktionen zu fördern. Mit Hilfe der Darstellung auf unterschiedlichen Abstraktionsebenen (Drill-Down-Prinzip) können sowohl sehr allgemeine Interaktionen zwischen Funktionsbereichen und Planungssystemen, aber auch sehr spezifische technische Prozesse auf unterster Tool-Ebene abgebildet werden. Insbesondere für komplexe Projekte, wie beispielsweise die Implementierung von Algorithmen der künstlichen Intelligenz bzw. des maschinellen Lernens in bestehende Unternehmensprozesse, bietet sich eine derartige Modellierung an, da sie für Transparenz und Verständnis der jeweiligen Prozessgegebenheiten sorgt. Daher kann die Interaktionsmodellierung als zentrales Kommunikationsmedium für unterschiedliche Stakeholder herangezogen werden und ist durch die Darstellung auf verschiedenen Abstraktionsstufen für unterschiedliche Kompetenzniveaus geeignet. In einem Anwendungsbeispiel wird die vorgestellte Modellierungstechnik für den Prozess der Absatzplanung eines Unternehmens eingesetzt. Dieser Prozess ist ein gutes Beispiel, da er bislang von vielen manuellen Interaktionen zwischen verschiedenen am Planungsprozess beteiligten Personen sowie mehreren maschinellen Anwendungssystemen geprägt war. Für das Anwendungsbeispiel ist die Modellierung neben der Dimension des Abstraktionsniveaus durch eine zusätzliche Perspektive, der Abbildung von IST- und SOLL-Prozess, angereichert worden. Auf diese Weise lassen sich durch das Heranziehen repräsentativer Kennzahlen, wie der Planungsgüte, wirkungsorientierte Veränderungen in der Mensch-Technik-Organisation quantitativ erfassen und sichtbar machen. So sollen insbesondere Veränderungen am Prozess verdeutlicht werden, um gegebenenfalls für künftige Entwicklungen der Rollen und Kompetenzen der beteiligten Planer zu sensibilisieren. Basierend auf diesen Erkenntnissen können Organisationen notwendige proaktive Maßnahmen, wie der Schulung bzw. Fortbildung von involvierten Personen ableiten. Dies wiederum führt zu einer grundsätzlichen Steigerung der Transparenz im Bereich der Konzeption, Umsetzung und Durchführung von entsprechenden komplexen Projektvorhaben, wie in diesem Anwendungsfall verdeutlicht wird. Das bisherige Fazit ist, dass die Modellierung im Unternehmen für die nötige Transparenz bei der KI-Implementierung im Prozess sorgt und als zentrales Kommunikationsmedium für diverse Abstimmungsrunden verschiedener Stakeholder herangezogen wurde. Basierend auf diesen Erkenntnissen liegt der Fokus im weiteren Projektverlauf auf den kommenden Wechselwirkungen und Effekten, die der Einsatz der entwickelten Algorithmen auf das Prozessökosystem im Bereich Mensch-Maschinen- Orchestrierungen erzielen und welche Handlungsempfehlungen im Sinne eines Best Practices sich hieraus ergeben werden.

Testo completoAbstract (sommario):
Die Förderung von Fahrradmobilität und öffentlichem Verkehr ist ein wesentlicher Baustein zur Gestaltung einer ökologisch nachhaltigeren, sozial verträglicheren und ökonomisch tragfähigen Verkehrs- und Siedlungsentwicklung in Deutschland. Mit einer verbesserten intermodalen Verknüpfung werden beide Verkehrsträger attraktiver und somit häufiger genutzt. Öffentliche Verkehrsunternehmen gewinnen dadurch vergrößerte Einzugsbereiche von Haltestellen, können Spitzenbelastungen abfedern und verbessern ihr Image. Fahrradfahrenden ermöglicht die Kombination mit öffentlichen Verkehrsmitteln größere Reichweiten, was gerade auch in randstädtischen, suburbanen oder ländlichen Regionen bedeutsam werden kann. Letztlich leistet die Verknüpfung der beiden Verkehrsträger einen Beitrag zur Daseinsvorsorge und für den Klimaschutz. Der Handlungsleitfaden wurde innerhalb des Forschungsprojektes „Verbesserte Integration des Fahrrads in den öffentlichen Verkehr – Systematische Erschließung von Handlungsoptionen und Bewertung von Best-Practices“ erarbeitet. Das Projekt wurde vom Bundesministerium für Verkehr und digitale Infrastruktur (BMVI) aus Mitteln zur Umsetzung des Nationalen Radverkehrsplans gefördert.

Die Verknüpfung des Fahrrades mit dem Öffentlichen Verkehr (ÖV) kann den Umweltverbund stärken, den Übergang von einem Verkehrssystem auf das andere erleichtern und eine attraktive Alternative zum motorisierten Individualverkehr schaffen. Die vorliegende Arbeit repräsentiert den ersten umfassenden Projektbericht innerhalb des Forschungsprojektes „Verbesserte Integration des Fahrrads in den öffentlichen Verkehr – Systematische Erschließung von Handlungsoptionen und Bewertung von Best-Practices“. Ziel dieser Publikation ist eine aktuelle Aufarbeitung des Standes der Forschung und der Praxis zu diesem Thema. Nach einer systematischen Darstellung wichtiger Forschungsstränge, werden zunächst Ergebnisse aus dem „Mobilität in Deutschland“-Datensatz hinsichtlich intermodaler Rad‐ÖV‐Nutzungsmuster präsentiert. Aufbauend darauf werden Datengrundlagen und generelle Erfordernisse an Erhebungsmethoden diskutiert, um die inter- und multimodale Verkehrsmittelnutzung tatsächlich beurteilen zu können. Die Darstellung des aktuellen Standes in der Praxis wird anhand von drei Schwerpunkt-Feldern vorgenommen: Bike and Ride Abstellanlagen an Haltestellen des ÖV, Radmitnahme in den Fahrzeugen des ÖV und Fahrradverleihsysteme. Dabei werden sowohl infrastrukturelle Maßnahmen als auch Betreiberkonzepte und Marketingaspekte behandelt. Ein weiteres Kapitel beschäftigt sich mit den Chancen und Herausforderungen im Zuge der fortschreitenden Digitalisierung und der Verbreitung von mobilen Endgeräten.

Die Verknüpfung des Fahrrades mit dem Öffentlichen Verkehr (ÖV) kann den Umweltverbund stärken, den Übergang von einem Verkehrssystem auf das andere erleichtern und eine attraktive Alternative zum motorisierten Individualverkehr schaffen. Die vorliegende Arbeit repräsentiert den zweiten umfassenden Projektbericht innerhalb des Forschungsprojektes „Verbesserte Integration des Fahrrads in den öffentlichen Verkehr – Systematische Erschließung von Handlungsoptionen und Bewertung von Best-Practices“. Im ersten Projektbericht (ebenfalls in dieser Arbeitspapierreihe erschienen – Nr. 15) wurden die Entwicklungen der letzten Jahre in den infrastrukturellen Themenfeldern Fahrradmitnahme, Fahrradverleihsysteme und Fahrradabstellanlagen aufgearbeitet und Fragen zu Kommunikation und Marketing der Angebote sowie zu Möglichkeiten der fortschreitenden Digitalisierung zur verbesserten Integration von Fahrrad und Öffentlichem Verkehr diskutiert. Darauf aufbauend werden im vorliegenden Bericht die Ergebnisse vertiefender Fallstudien dargestellt, mit dem Ziel, Erfolgsfaktoren und Hemmnisse für die Integration von Fahrrad mit Öffentlichem Verkehr aufzuzeigen und in einem späteren Schritt daraus Handlungsempfehlungen zur Stärkung dieser Integration für Kommunen und Verkehrsanbieter geben zu können. Für die Fallstudien wurden solche Beispiele ausgewählt, die einen Vorbildcharakter haben und als nachahmenswert für andere Städte und Regionen gelten können bzw. aus denen sich Erkenntnisse für die Stärkung der Integration von Fahrradverkehr mit dem ÖV ziehen lassen. Zudem sollten die verschiedenen infrastrukturellen Themenfelder abgedeckt sein.

The major bottlenecks in rearing the highly priced gastropod abalone (Haliotis spp.) are the slow growth rate and the high mortality during the first 8 to 12 weeks following metamorphosis and settling. The most likely reason flor these problems is related to nutritional deficiencies in the diatom diet on which the post larvae (PL) feed almost exclusively in captivity. Higher survival and improved growth rate will reduce the considerable expense of hatchery-nursery resisdence time and thereflore the production costs. BARD supported our research for one year only and the support was given to us in order to prove that "(1) Abalone PL feed on encapsulated diatoms, and (2) heterotrophic diatoms can be mass produced." In the course of this year we have developed a novel nutrient delivery system specifically designed to enhance growth and survival of post-larval abalone. This approach is based on the sodium-alginate encapsulation of heterotrophically grown diatoms or diatom extracts, including appetite-stimulating factors. Diatom species that attract the PL and promote the highest growth and survival have been identified. These were also tested by incorporating them (either intact cells or as cell extracts) into a sodium-alginate matrix while comparing the growth to that achieved when using diatoms (singel sp. or as a mixture). A number of potential chemoattractants to act as appetite-stimulating factors for abalone PL have been tested. Preliminary results show that the incorporation of the amino acid methionine at a level of 10-3M to the sodim alginate matrix leads to a marked enhancement of growth. The results ol these studies provided basic knowledge on the growth of abalone and showed that it is possible to obtain, on a regular basis, survival rates exceeding 10% for this stage. Prior to this study the survival rates ranged between 2-4%, less than half of the values achieved today. Several diatom species originated from the National Center for Mariculture (Nitzchia laevis, Navicula lenzi, Amphora T3, and Navicula tennerima) and Cylindrotheca fusiformis (2083, 2084, 2085, 2086 and 2087 UTEX strains, Austin TX) were tested for heterotrophic growth. Axenic colonies were initially obtained and following intensive selection cycles and mutagenesis treatments, Amphora T3, Navicula tennerima and Cylindrotheca fusiformis (2083 UTEX strain) were capable of growing under heterotrophic conditions and to sustain highly enriched mediums. A highly efficient selection procedure as well as cost effective matrix of media components were developed and optimized. Glucose was identified as the best carbon source for all diatom strains. Doubling times ranging from 20-40 h were observed, and stable heterotroph cultures at a densities range of 103-104 were achieved. Although current growth rates are not yet sufficient for full economical fermentation, we estimate that further selections and mutagenesis treatments cycles should result in much faster growing colonies suitable for a fermentor scale-up. As rightfully pointed out by one of the reviewers, "There would be no point in assessing the optimum levels of dietary inclusions into micro-capsules, if the post-larvae cannot be induced to consume those capsules in the first place." We believe that the results of the first year of research provide a foundationfor the continuation of this research following the objectives put forth in the original proposal. Future work should concentrate on the optimization of incorporation of intact cells and cell extracts of the developed heterotrophic strains in the alginate matrix, as well as improving this delivery system by including liposomes and chemoattractants to ensure food consumption and enhanced growth.

Testo completoAbstract (sommario):
The objective of this project is to provide information about a problem material found in gas pipelines called "black powder". It is a mixture or a chemical compound of iron sulfides, iron oxides, dirt, sand, salts, chlorides, water, glycols, hydrocarbons and compressor oils, mill scale, or other materials. The most common constituents, iron compounds of sulfur or oxygen, are corrosion products. In addition to chemical formation, black powder can be formed by microbes normally found in gas pipelines. This material causes machinery, measurement, and pipeline maintenance problems. This research investigates the forms of iron sulfides, their characteristics, and methods of formation and whether the molecular form can be an indicator of the source of the material. A sampling protocol was developed for proper collection of materials for analysis. Seventeen corrosion samples were collected and analyzed for material constituents and microbial content. The results of this testing were anonymously tabulated in a database. Other tasks in this project include guidelines for removal, handling, and disposal of the material. It discusses symptomatic versus root cause treatments for the prevention and control of black powder, and the corporate culture necessary to manage the problem. It presents recently developed technologies for cleaning or treating a pipeline containing black powder, such as cleaning and anti-microbial agents containing THPS which dissolve iron sulfides, and the use of magnetic filtration. The final task describes concepts for identifying the location of black powder in an operating pipeline and places to look and methods to use to best determine the distribution of the material.

Testo completoAbstract (sommario):
Research objectives were: 1) To study the effect of diet energy density, level of exercise, thermal conditions and reproductive state on cardiovascular function as it relates to oxygen (O2) mobilization. 2) To validate the use of heart rate (HR) to predict energy expenditure (EE) of ruminants, by measuring and calculating the energy balance components at different productive and reproductive states. 3) To validate the use of HR to identify changes in the metabolizable energy (ME) and ME intake (MEI) of grazing ruminants. Background: The development of an effective method for the measurement of EE is essential for understanding the management of both grazing and confined feedlot animals. The use of HR as a method of estimating EE in free-ranging large ruminants has been limited by the availability of suitable field monitoring equipment and by the absence of empirical understanding of the relationship between cardiac function and metabolic rate. Recent developments in microelectronics provide a good opportunity to use small HR devices to monitor free-range animals. The estimation of O2 uptake (VO2) of animals from their HR has to be based upon a consistent relationship between HR and VO2. The question as to whether, or to what extent, feeding level, environmental conditions and reproductive state affect such a relationship is still unanswered. Studies on the basic physiology of O2 mobilization (in USA) and field and feedlot-based investigations (in Israel) covered a , variety of conditions in order to investigate the possibilities of using HR to estimate EE. In USA the physiological studies conducted using animals with implanted flow probes, show that: I) although stroke volume decreases during intense exercise, VO2 per one heart beat per kgBW0.75 (O2 Pulse, O2P) actually increases and measurement of EE by HR and constant O2P may underestimate VO2unless the slope of the regression relating to heart rate and VO2 is also determined, 2) alterations in VO2 associated with the level of feeding and the effects of feeding itself have no effect on O2P, 3) both pregnancy and lactation may increase blood volume, especially lactation; but they have no effect on O2P, 4) ambient temperature in the range of 15 to 25°C in the resting animal has no effect on O2P, and 5) severe heat stress, induced by exercise, elevates body temperature to a sufficient extent that 14% of cardiac output may be required to dissipate the heat generated by exercise rather than for O2 transport. However, this is an unusual situation and its affect on EE estimation in a freely grazing animal, especially when heart rate is monitored over several days, is minor. In Israel three experiments were carried out in the hot summer to define changes in O2P attributable to changes in the time of day or In the heat load. The animals used were lambs and young calves in the growing phase and highly yielding dairy cows. In the growing animals the time of day, or the heat load, affected HR and VO2, but had no effect on O2P. On the other hand, the O2P measured in lactating cows was affected by the heat load; this is similar to the finding in the USA study of sheep. Energy balance trials were conducted to compare MEI recovery by the retained energy (RE) and by EE as measured by HR and O2P. The trial hypothesis was that if HR reliably estimated EE, the MEI proportion to (EE+RE) would not be significantly different from 1.0. Beef cows along a year of their reproductive cycle and growing lambs were used. The MEI recoveries of both trials were not significantly different from 1.0, 1.062+0.026 and 0.957+0.024 respectively. The cows' reproductive state did not affect the O2P, which is similar to the finding in the USA study. Pasture ME content and animal variables such as HR, VO2, O2P and EE of cows on grazing and in confinement were measured throughout three years under twenty-nine combinations of herbage quality and cows' reproductive state. In twelve grazing states, individual faecal output (FO) was measured and MEI was calculated. Regression analyses of the EE and RE dependent on MEI were highly significant (P<0.001). The predicted values of EE at zero intake (78 kcal/kgBW0.75), were similar to those estimated by NRC (1984). The EE at maintenance condition of the grazing cows (EE=MEI, 125 kcal/kgBW0.75) which are in the range of 96.1 to 125.5 as presented by NRC (1996 pp 6-7) for beef cows. Average daily HR and EE were significantly increased by lactation, P<0.001 and P<0.02 respectively. Grazing ME significantly increased HR and EE, P<0.001 and P<0.00l respectively. In contradiction to the finding in confined ewes and cows, the O2P of the grazing cows was significantly affected by the combined treatments (P<0.00l ); this effect was significantly related to the diet ME (P<0.00l ) and consequently to the MEI (P<0.03). Grazing significantly increased O2P compared to confinement. So, when EE of grazing animals during a certain season of the year is estimated using the HR method, the O2P must be re measured whenever grazing ME changes. A high correlation (R2>0.96) of group average EE and of HR dependency on MEI was also found in confined cows, which were fed six different diets and in growing lambs on three diets. In conclusion, the studies conducted in USA and in Israel investigated in depth the physiological mechanisms of cardiovascular and O2 mobilization, and went on to investigate a wide variety of ruminant species, ages, reproductive states, diets ME, time of intake and time of day, and compared these variables under grazing and confinement conditions. From these combined studies we can conclude that EE can be determined from HR measurements during several days, multiplied by O2P measured over a short period of time (10-15 min). The study showed that RE could be determined during the growing phase without slaughtering. In the near future the development microelectronic devices will enable wide use of the HR method to determine EE and energy balance. It will open new scopes of physiological and agricultural research with minimizes strain on animals. The method also has a high potential as a tool for herd management.
