Resumen

I prepared a “model farm” producing fattening pigs in order to examine the main risk of production and market factors affecting the profitability of fattening pig production. Values of body weight (at the beginning of fattening and at the end of fattening), mortality rate, feed conversion ratio (FCR) of fattening pig as well as the main cost and price data were recorded as the input data of the model. Production value per unit, production cost per unit and income per unit were used as output. The Monte-Carlo simulation was used in the model for risk assessment. Based on the results of the analysis, it was concluded that the production value per unit was most affected by the selling price of fattening pig (ß=0.972), the production cost per unit were most influenced by the body weight at the beginning of fattening (ß=0.567) and the feed conversion ratio (ß=0.537), in addition, the change of the income per unit was most determined by the previously factors.

Resumen

The aim of this study was to establish the total fungal (mould) count in 79 commercial pig farm feed samples (42 samples for piglets, 29 samples for fattening pigs and 8 samples for sows) collected from the Serbian feed producers during the three-year period (2017-2019), as well as to evaluate the percentage of contamination samples by fungi, especially species from Aspergillus, Fusarium and Penicillium genera. Using standard mycological methods, the total count and identification of fungi were determined. Total fungal count was ranging from 1 ? 102 to 1.41 ? 105 cfu g-1 in the feed samples for piglets. Furthermore, in the feed samples for fattening pigs it ranged from1 ? 102 to 2.54 ? 105 cfu g-1, and from 1 ? 102 to 1.93 ? 105 cfu g-1 in the feed samples for sows. It has established the impermissible limit of total fungal count in 3.45% and 4.76% of a feed for fattening pigs and feed for piglets, respectively. Statistical analysis of the total number of fungi did not establish significant differences between the examined feed groups. Fusarium species were present in the most feed samples for fattening pigs (65.52%), followed by the feed for sows (62.50%) and piglets (47.62%). Aspergillus species were determined in 59.52, 58.62 and 37.50% feed samples for piglets, fattening pigs and sows, respectively. Penicillium species contaminated the lowest percentage of feed samples for fattening pigs (27.59%) and the highest percentage of feed samples for sows (37.50%). In a small number of samples Alternaria, Mucor, and Rhizopus species were identified. Based on these results, it can be concluded that the investigation of fungal contamination is an important indicator of a hygienic condition of feed intended for the nutrition of farm pigs. In addition, the percentage of fungal contamination of the examined samples indicates a potentially high risk to animal health. Due to that, a regular mycological evaluation is necessary to assess nutritional quality as one of the fundamental criteria for feed safety.

Resumen

Early detection of emerging carbapenem-resistant Enterobacteriaceae (CPE) in food-producing animals is essential to control the spread of CPE. We assessed the risk of CPE introduction from imported livestock, livestock feed, companion animals, hospital patients, and returning travelers into livestock farms in The Netherlands, including (1) broiler, (2) broiler breeder, (3) fattening pig, (4) breeding pig, (5) farrow-to-finish pig, and (6) veal calf farms. The expected annual number of introductions was calculated from the number of farms exposed to each CPE source and the probability that at least one animal in an exposed farm is colonized. The total number of farms with CPE colonization was estimated to be the highest for fattening pig farms, whereas the probability of introduction for an individual farm was the highest for broiler farms. Livestock feed and imported livestock are the most likely sources of CPE introduction into Dutch livestock farms. Sensitivity analysis indicated that the number of fattening pig farms determined the number of high introductions in fattening pigs from feed, and that uncertainty on CPE prevalence impacted the absolute risk estimate for all farm types. The results of this study can be used to inform risk-based surveillance for CPE in livestock farms.

Resumen

At present, two types of fattening are carried out in Iberian traditional pig production. The montanera is the fattening system where fatteners are fed on acorns and pasture in the dehesa, and cebo de campo is the fattening where the pigs are fed on compound feed and natural resources, mainly pasture. The aim of this paper is to analyze Iberian fattening production from an economic and environmental approach in order to identify fattening strategies to increase the sustainability of this traditional livestock activity. Based on technical-economic and environmental variables, the differences between Iberian farms according to the types of fattening were determined using discriminant analysis techniques. The model based on environmental variables showed a greater predictive ability than that found in the model based on technical-economic variables. Consequently, environmental variables can be used as reference points to classify the Iberian farms according to the type of fattening. Furthermore, canonical correlation analysis allowed to study the relationships between both sets of variables, showing that environmental values had a strong correlation with technical-economic variables. The results of this study show that it is possible to improve the sustainability of Iberian traditional pig production through fattening strategies in both types of fattening.

Resumen

The introduction of the euro is one of the great achievements of the European integration process. We ask whether the creation of the euro led to a significant increase in pig meat trade in the eurozone. The pig meat industry is the most important in the European meat sector, and the EU is the world's second-biggest producer of pork and the leading supplier of pig meat to the global market. No study has yet been conducted in this respect for this sector. Our results suggest that pig meat trade was encouraged between countries sharing the euro, although the impact of EU single market was still greater. Trade creation was also observed, increasing pig meat exports from eurozone to non-eurozone countries. Also, non-eurozone EU exporters suffer from a diversion effect that benefits eurozone exporters.

Resumen

The main aims of research were: to measure the surface tension (ST) values of hybrid pig blood; to establish the relationships between these ST-values and obtained biochemical parameters of the same blood samples. All studied animals (n=43) were healthy and grown at the feeding stations (Russia). The ST-values (measured using PAT-device) of the pig blood were obtained at initial (n=30) and final (n=13) points of animal fattening. The following correlations between eST at final (or initial) point of pig fattening and the biochemical parameters were obtained: +0.80 (+0.19) with the ratio of albumins to globulins (A/G), -0.39 with globulins (-0.38) with phospholipids, +0.32 (+0.40) with the “de Ritis” coefficient, -0.52 (+0.35) with Cl. The correlations between eTA at same fattening points and the biochemical parameters were obtained: +0.32 with A/G ratio, +0.18 with globulins, +0.36 with phospholipids, +0.28 (+0.17) with the “de Ritis” coefficient, -0.32 (+0.21) with Mg, +0.35 with Fe, +0.30 with Cl, +0.31 (+0.34) with the ratio of calcium to phosphorus (Ca/P). Such tendency indicated the stabilization of pig physiological-biochemical status during their fattening. The authors recommended the following eST (42-46 mN/m) and eTA (10-30 mN·m-1·s-½) blood parameters as reference values for further applications in husbandry.

Resumen

HighlightsUnder the same conditions of cast-iron usage, increasing the width of the gap and slat width within a certain range can enhance the bearing capacity of the slatted floors.Variations in the gap and slat width do not significantly affect pig growth performance.The recommended gap width of a cast-iron slatted floor in a fattening pig house is 15 mm.Abstract.Slatted flooring is an important part of the structure of pig houses and can aid in the removal of pig manure to underground ditches via gravity and locomotion. In this study, four different cast-iron slatted floor configurations with different gap widths (10, 15, and 20 mm) and slat widths (10 and 15 mm) were set up in 11 partially slatted-floor pig pens of the same size, each housing 10 fattening pigs with body weights of approximately 63 kg. The residual manure on the solid concrete floor area and a cast-iron slatted floor area were collected at different time intervals (24, 48, and 72 h) and weighed. According to previous studies on total manure and total urine production of pigs, the manure drainage capacity of four types of slatted floor was calculated. The growth performance of all of the pigs was monitored throughout the experiment. The ultimate bearing capacity of the four types of slatted floors was measured by a third-party professional testing organization. The results showed that the gap width and slat width of the cast-iron slatted floor had significant effects on its ultimate bearing capacity and manure drainage capacity (P<0.05) but had no significant effect on pig growth performance (P>0.05). The recommended gap width of a cast-iron slatted floor in a fattening pigs house is 15 mm. These findings can be used to optimize the design of cast-iron slatted flooring for fattening pigs, which must also be safe, economical, and efficient. Keywords: Cast iron, Dimensions, Fattening pig, Manure drainage, Slatted floor.

Resumen

Noch vor 50 Jahren stand Roggen an erster Stelle im Getreideanbau, erst mit Abstand folgte der Weizen . Gerste wurde meist nur als Sommerfrucht angebaut und der Mais war noch ein Exot. Die Pflanzenzüchtung bewirkte eine grundlegende Änderung der Anbaugewohnheiten. Roggen erwies sich bei der züchterischen Verbesserung als schwieriger und sein langes Stroh störte bei der Ernte mit dem Mähdrescher. Roggen wurde deshalb auf die geringerwertigeren Böden mit hohem Sandanteil abgedrängt. Durch eine neue Methode der Pflanzenzüchtung, die Hybridzüchtung, kann Roggen heute im Ertrag auf vielen Standorten wieder mit dem Weizen konkurrieren. Mit der vorliegenden Veröffentlichung wird erläutert, ob höhere Roggenanteile in der Ferkel- und Mastschweinefütterung vertretbar sind.

Resumen

Hos grisar finner man flera stereotypiska beteenden, som rörbitning och svansbitning. Dessa beteenden är relativt vanliga hos grisar. En miljöberikning definieras som förbättring av ett djurs välfärd, både psykologisk och fysiologiskt, genom förändringar hos djurets omgivning. Denna studie har undersökt om miljöberikningar kan minska stereotypiska beteenden hos grisar. De två olika miljöberikningar som har använts är en jutesäck fylld med halm och en Jolly Ball™. De tre stereotypiska beteendena som studerades var rörbitning, svansbitning och bukmassage. Studien utfördes på 107st grisar uppdelade på 12 boxar, under totalt tre veckor. Alla tre stereotypiska beteenden minskade statistiskt signifikant . Detta visar att båda miljöberikningarna hade en positiv effekt på grisarna då de minskade deras stereotypiska beteenden. De interagerade mer med jutesäcken fylld med halm än vad det gjorde med Jolly Ball™. Grisarna föredrog den miljöberikningen som var omformbar, förstörbar, ätbar, tuggbar, vilket går i linje med liknande studier.
Among fattening pigs you find several stereotypical behaviours, such as bar-biting and tail-biting. These behaviours are quite common among domestic pigs. Environmental enrichments are often used to reduce stereotypical behaviours in animals. An environmental enrichment is defined as an improvement of an animal’s welfare, both psychologically and physiologically, through changes in the environment of the animal. With this study, different environmental enrichments were studied to see if they can reduce stereotypical behaviour among fattening pigs. The two different environmental enrichments used were a jute sack filled with straw and a Jolly Ball™. The stereotypical behaviours that were looked at were bar-biting, tail-biting and belly-nosing. The study was carried out on 107 pigs divided into 12 pig boxes, during 3 weeks in total. All three stereotypical behaviours decreased significantly. This shows that the environmental enrichments had a positive effect on the pigs, since they reduced their stereotypical behaviour. The pigs interacted more with the jute sack than they did with the Jolly Ball™. The pigs preferred the environmental enrichment that was destructible, edible, deformable and chewable, which fits well into similar studies that have been executed.

Resumen

Aquest treball de tesis doctoral tracta de la Optimització de la fase d'engreix. L'objectiu és determinar les condicions d'enviament a sacrifici d'un lot d'animals des d'un punt de vista operatiu. En primer lloc es fa una anàlisi de la cadena de producció de carn porcina, resaltant-ne els canvis del sector que han influit en la fase d'engreixament. La conclusió d'aquesta anàlisi és el plantejament d'un model per prendre decisions degut al canvi de paradigma que s'evidencia: els productors de porcs en la fase d'engreix cal que orientin la gestió del paràmetres operatius i els productes finals a les exigències i gustos dels seus clients. Seguidament, es presenta el sistema d'ajut a la decisió basat en un model biològic que explica l'evolució de les variables productives (pes i consum de pinso). A més també prediu les variables associades a característiques de la canal, com són el percentatge de magre, la proporció de peces, el rendiment i el greix intramuscular. El sistema té en compte tres mercats de carn porcina alternatius: 1) basat en pes viu, 2) basat en mèrits de la canal (percentatge de magre) y 3) basat en el valor de les peces nobles resultants de l'especejament de l'animal. L'objetiu del sistema és determinar la millor estratègia d'enviament per a cadascun dels genotips que s'han estudiat (alternatives de producció) depenent del mercat on seran enviats els animals. A més, també ha estat estudiat l'efecte de la variabilitat biològica dels animals dins del lot sobre els valors econòmics. També s'ha considerat l'opció d'enviar els animals en diverses etapes per tal d'homogeneitzar el pes dels animals enviats. Aquest problema ha estat estudiat seguint l'enfocament de programació dinàmica. En els darrers capítols es presenten quatre aplicacions del model que s'han desenvolupat al llarg del treball. En un futur els mercats de carn porcina tindran la tendència a ser més definits, per tant la producció en la fase d'engreixament porcí hauria d'integrar i tenir en compte les demandes i les exigències del consumidor.
This PhD Thesis is related to optimisation of pig fattening phase under an operative point of view. Firstly it has been an analysis of the Pork Chain in order to establish a framework. The objective is to highlight the changes in the sector which have influenced on fattening phase. The result was the necessity of satisfying the consumer demands. In the following chapters a Decision Support was developed based on the consumers requirements. Based on a biological model, a managerial model has been developed to analyse the fattening phase. The decision support system takes into account three alternative pig meat markets: Live body weight pricing, carcass merit pricing, and components or cuts pricing system. Apart from the alternatives markets, its objective is to determine the best marketing strategy for each different genotypes (production alternatives) depending on the market where they will be sent. In addition, the effect of animal variability on economic figures has been studied. Also it has been considered the option of marketing the animals in different stages in order to homogenise the weight of animal sent. This problem has been treated under dynamic programming framework. In near future pig meat markets are going to be more defined, therefore the fattening phase of pork production must take consumer demands into account.

Resumen

From quinua crop residue it is possible to obtain byproducts that can be used to feed small animals, especially guinea pigs. These byproducts can become an alternative feed to ameliorate food deficiencies generally present in the Altiplano. This study compared the effect of consumed quinua meal rations on guinea pig body weight increase and food and economic conversion. This project was developed in two phases: pre-experimental and experimental. In the first phase, genetic material appropriate for the project and the initial rations for consumption was acquired. The second phase included the experimental design where the treatments were developed. The study concluded that a diet of 30% of dry quinua residue completely substituted a diet of wheat meal. This study also presented information on a bactericidal effect of consumed quinua in the digestive tract, resulting in improved weight increase and feed conversion.

Resumen

Dissertação de Mestrado Integrado em Medicina Veterinária
A implementação de programas de monitorização de lesões detetadas durante a inspeção post mortem é uma realidade cada vez mais presente nos países da União Europeia. Com estes é possível auxiliar o produtor a conseguir lotes de animais mais saudáveis, promovendo a saúde animal, o seu bem-estar e um melhor desempenho produtivo. Neste trabalho procurou-se estudar a incidência e gravidade de diversos processos patológicos detetados na linha de abate que se encontram normalmente associados a diminuição do desempenho produtivo dos animais ou que podem ser indicadores de problemas de bem-estar animal. Complementarmente, realizou-se uma comunicação mensal dos resultados da inspeção ao médico veterinário das respetivas explorações de origem dos animais. O estudo foi desenvolvido numa amostra de 15894 suínos de engorda, pertencentes a 118 lotes. Cada animal era avaliado quanto à presença de lesões sugestivas de pneumonia enzoótica, pneumonia vírica, pleuropneumonia, abcessos pulmonares, pioémia, pleurisia, pericardite, peritonite, lesões focais de hepatite intersticial crónica (“manchas leitosas”), cicatrizes hepáticas, dermatite papular e lesões na cauda. Os resultados obtidos revelaram que as lesões com localização no sistema respiratório, nomeadamente as lesões sugestivas de pneumonia enzoótica e pleurisia, foram as mais frequentes nas explorações em estudo, tendo sido identificadas praticamente na totalidade dos lotes. No entanto, outras lesões também foram identificadas nos lotes estudados tendo sido bastante elevada a sua frequência, o que confirma o grande impacto negativo que têm tanto no bem-estar animal como na economia das suiniculturas.
ABSTRACT - ANIMAL WELFARE AND POST MORTEM LESIONS IN PIGS - The implementation of lesions recording systems on slaughterhouses is becoming an increasingly common practice in the countries of the European Union. These help the producer to achieve healthier batches, promoting animal health, their welfare and improvements in productivity. The aim of this study was to investigate the incidence and severity of various pathologies detected in slaughtered pigs. These pathologies are usually associated with a reduction in performance traits or are potential indicators of the presence of welfare problems in the herds. In addition, a monthly report with the monitoring results was sent to the herd’s veterinarian. A sample of 15894 fattening pigs belonging to 118 batches was studied. For each animal was recorded the presence of enzootic pneumonia-like lesions, viral-like pneumonia, pleuropneumonia, pulmonary abscesses, pyaemia, pleurisy, pericarditis, peritonitis, chronic focal interstitial hepatitis ("milk spots"), hepatic scarring, papular dermatitis and tail damage. The results obtained suggest that respiratory lesions, such as enzootic pneumonia-like lesions and pleurisy, are the ones that are most present in the farms under study, both of which have been identified in almost every batches. However, other lesions were also frequently identified in batches and showing high prevalence, confirming the great impact that these have on animal welfare as well as on economic level.

The experiment was performed on a total of 90 hybrid pigs divided into experimental groups based on their origin (litter), sex and initial body weight. The pigs were assigned to six experimental groups (15 animals per group): group 1 – animals fed a complete diet and kept freerange, group 2 – animals fed a complete diet and kept indoors in pens with litter bedding, group 3 - animals fed a complete diet and kept indoors in pens without litter bedding, group 4 – animals fed a complete diet and alfalfa forage, kept free-range, group 5 - animals fed a complete diet and alfalfa forage, kept indoors in pens with litter bedding, group 6 - animals fed a complete diet and alfalfa forage, kept indoors in pens without litter bedding. All management systems were animal welfare-friendly. Both at the first and second stage of fattening (approx. 50 kg and 100 kg BW, respectively), the experimental factors had a significant effect on the majority of behavior patterns in pigs. An increase in rest periods and a reduction in locomotor activity and other types of behavior were observed in older animals.

Resumen

Hintergrund und Zielstellung: Im Zuge der Intensivierung der Schweinemast kommen Atemwegsinfektionen und deren klinische Auswirkungen auf die Tiere, in Verbindung mit möglichen Wechselwirkungen zu den Umgebungsfaktoren, eine entscheidende Bedeutung für die Tiergesundheit und Wirtschaftlichkeit der Betriebe zu. Daher war es Ziel dieser Arbeit, unter Feldbedingungen festzustellen, inwieweit Korrelationen zwischen Parametern des Stallklimas, dem Nachweis potentiell pathogener Infektionserreger des Respirationstraktes, klinischem Befund der Tiere, dem Lungenbefund am Schlachtband und den Leistungsfaktoren bestehen. Material und Methoden: Über den Zeitraum von einem Jahr wurden fünf Schweinemastbetriebe in Thüringen, mit Betriebsgrößen im Bereich von 2480 bis 22 000 Mastplätzen hinsichtlich Tiergesundheit, insbesondere der Atemwegsgesundheit und Stallklima untersucht. Betriebskenndaten über Stallbau, Belegungsdichte, Lüftungs- und Heiztechnik sowie Fütterungs, -Tränke- und Impfregime wurden aufgenommen. Für die Untersuchungen wurden pro Betrieb zwei Abteile ausgewählt. Dabei lagen die betriebsabhängigen Abteilgrößen zwischen 159 bis 751 Tieren. In diesen Abteilen wurden bei einer Stichprobengröße von zehn Tieren in zwei Mastperioden, Sommer und Winter, zu jeweils drei Zeitpunkten (Vormast, Mittelmast und Endmast) 840 Blutproben entnommen und bezüglich der lungenpathogenen Erreger PRRSV, PCV 2, SIV sowie APP untersucht. PRRSV und PCV 2 betreffend, wurde sowohl auf Virus mittels in house-PCR-Untersuchungen gepoolter Proben, als auch serologisch auf Antikörper mittels ELISA untersucht. Für den Erreger SIV erfolgte eine serologische Untersuchung auf Antikörper mittels HAH sowie für APP mittels ELISA. Des Weiteren kam es in den entsprechenden Abteilen zur Durchführung stallklimatischer Messungen, wobei die Stallklimaparameter Lufttemperatur, Relative Luftfeuchte, Luftgeschwindigkeit sowie die Beleuchtungsstärke mithilfe von Geräten der Firma Testo sowie die Konzentrationen von CO2, O2, NH3und H2S mithilfe eines Multiwarn-Mehrgasmessgeräts der Firma Dräger ermittelt wurden. Gleichzeitig erfolgte eine klinische Befunderhebung in den Gruppen, mit der Bildung eines Klinikscores mit Schwerpunkt Lungengesundheit, sowie die Aufnahme der Leistungsparameter: durchschnittliche tägliche Zunahme, Mortalität der Gruppe und dem Tierbehandlungsindex, aus denen ein Leistungsscore ermittelt wurde. Im Zuge der Schlachtung wurden 9921 Schlachtkörper, insbesondere das Geschlinge und die Lungen, makroskopisch beurteilt und daraus ein modifizierter Organboniturscore, auf Grundlage des Organbefundindex nach Blaha gebildet. Alle Score-Bewertungen erfolgten nach Punkten und gaben somit eine Aussage zum Tiergesundheitsstatus der Betriebe. Höhere Punktzahlen entsprachen einem schlechterem Gesundheits- bzw. Leistungsstatus. Somit konnten Wechselwirkungen zwischen den Ergebnissen der Blutuntersuchungen, den Stallklimaparametern, dem Klinik- und Leistungsscore sowie dem Organboniturscore mittels statistischer Auswertung hergestellt werden, wobei die einzelnen Bestände sowohl betriebsübergreifend als auch auf Bestandsebene untersucht wurden. Aufgrund durchgeführter Umbaumaßnahmen in drei Beständen wurde ein Vergleich alter und neuer Betriebsteile in die Betrachtungen mit einbezogen. Ergebnisse: Keiner der Betriebe wies eine vollständige Erregerfreiheit auf, was für die endemische Verbreitung der Infektionserreger, insbesondere PRRSV, PCV 2 sowie APP spricht. SIV wurde lediglich in einem Bestand nachgewiesen. Serokonversionen hinsichtlich PRRSV gingen signifikant mit vermehrtem Husten der Tiere (p = 0,027) und einer höheren klinischen Gesamtpunktzahl (p = 0,016) einher. Bei Virusnachweis zeigte sich mit p = 0,047 eine signifikant schlechtere Lungengesundheit. Hinsichtlich des Stallklimas bestand für die Parameter Temperatur, Relative Luftfeuchte, CO2 Gehalt sowie den Schadgasgehalten der Stallluft ein starker Bezug zu den unterschiedlichen Mastperioden Sommer und Winter, mit vorrangig schlechteren Werten in der Winterperiode. Diese Klimaparameter lagen oftmals über den Grenz- bzw. Regelwertbereichen, mit Auswirkungen auf die Atemwegsgesundheit. Mit Ausnahme des Parameters NH3 ergaben sich bestandsübergreifend mit p ≤ 0,01 signifikante Zusammenhänge zu den klinischen Befunden (höhere Teilpunkzahlen Lungengesundheit korrelieren mit ρ = 0,250 zum CO2-sowie mit ρ = 0,222 zum H2S-Gehalt der Stallluft, negativ mit ρ = −0,396 zur Temperatur) sowie NH3 inbegriffen (mit einer Korrelation von ρ = 0,401) zu den Pneumoniebefunden. Ebenfalls bestandsübergreifend zeigte sich ein signifikanter Zusammenhang zwischen der Infektion von APP (p = 0,038) sowie PRRSV (p = 0,001) und einer erhöhten Anzahl an Pleuritiden. Des Weiteren zeigten sich mit einer Signifikanz von p ≤ 0,01 in Verbindung mit verstärkten klinischen Symptomen auch signifikant mehr makroskopisch sichtbare Pneumonien bei der Schlachtung (Korrelation der Gesamtpunktzahl Klinik mit ρ = 0,297). Bestandsabhängig wurden beim Vorhandensein multipler Erregerspektren im Betrieb erhöhte Lungenbefunde ermittelt. Beziehungen der Klima- und Klinikparameter sowie der Lungenbefunde zu den Leistungsparametern, konnten nur in geringem Maße festgestellt werden. So wurden beispielsweise keine Korrelationen zwischen den Schadgasparametern und der durchschnittlichen Masttagszunahme festgestellt. Hier scheint der genetische Aspekt einen starken Einfluss zu besitzen. Schlussfolgerungen: Anhand der Untersuchungen konnten sowohl einzelbetrieblich als auch betriebsübergreifend Signifikanzen zwischen den einzelnen Parametern festgestellt werden. Die gegenseitige Beeinflussung und Abhängigkeit aller Faktoren ist jedoch immer herdenabhängig und variiert, je nach Bestandsdynamik.

Resumen

Pigs are susceptible to a wide range of diseases that can affect health, welfare and productivity. The implementation of biosecurity measures along the production chain is one of the major solutions to minimize the risk of introduction of diseases into a farm (external biosecurity), as well as their spread within the farm (internal biosecurity). In this chapter, we discuss the five principles of farm-level biosecurity and illustrate the application of these principles both for external biosecurity (purchasing and quarantine policy, the transport of animals and removal of manure and carcasses, the supply of feed, water, and equipment, the access of persons, vermin and bird control, environmental risks) and for internal biosecurity (compartmentalization, working lines, and equipment, disease management, farrowing and suckling period, weaning and fattening period, and cleaning and disinfection). Finally, ways to measure and quantify the biosecurity status of a pig farm are discussed.
