Full textThe aim of this experiment was evaluate of the effect of the supplementation of adult bulls with calcium soaps of polyunsaturated fatty acids (PUFA) on the qualitative characteristics of the semen subjected to cryopreservation and thawing. Twenty adult bulls Angus, Hereford, Brangus and Braford were randomly assigned into two groups; they were subjected to two types of treatment: (SF) calcium soap; (SE) and energy source. The bulls were kept in individual pens and, during 77 days, they were fed on isoenergetic diets prepared with green grass, commercial concentrate, mineral salt, and calcium soaps of PUFA or energy supplement. The treatment supplemented with calcium soaps of PUFA received 200 g/d of Megalac-E®; and the treatment supplemented with other energy source received 750 g/d from cassava meal (Manihot esculenta, Crantz). During the period of the experiment, five collections of semen were performed with artificial vagina; the semen samples were evaluated considering the following variables: seminal volume, sperm concentration, sperm motility, morphology, evaluation of acrosome intact and differentiation of live and dead spermatozoa by staining tripan blue/giemsa, evaluation of the integrity membrane sperm through hypoosmotic swelling test (HO) and evaluation of longevity of sperm using the heat resistance tests (TTR). Two blood samplings were performed for assessing the concentration of blood testosterone. The results regarding the volume, sperm concentration and blood testosterone concentrations did not differ significantly between treatments during the experimental period. The group supplemented with calcium soaps of PUFA presented improvements in the percentages of sperm motility (83.3% vs. 75.3%). The percentages of live sperm (94,8% vs. 91,8%) and those with intact acrosome (98,0% vs. 96,6%) were higher compared with the group that received energy supplement. No significant differences were found between treatments in the percentages of the post-freezing motility and the motility of sperm subjected to TTR after 30 minutes and after 60 minutes showed no significant differences between treatments. The results of HO were not different between the groups with functional and energy supplement. During the supplementation period, the group with functional supplement presented higher percentages of live sperm (51,5% vs. 42,2%) and sperms with intact acrosome (48,0% vs. 39,2%) when compared with the group that received energy supplement. Supplementation with calcium soaps of PUFA can provide better features and higher resistance to sperm when submitted to the process of cryopreservation and thawing.

Full textThe objective was to evaluate the effects of addition of different concentrations of the isomers cis-9, trans-11 and trans-10, cis-12 conjugated linoleic acid (CLA) to the freezing medium on sperm motility, the plasma membrane integrity, acrosomal and mitochondrial of bovine sperm. In the experiment, four Jersey bulls were used, and the ejaculates processed as "pool" (experiment 1) and individually (experiment 2). The diluent medium was based on tris (Dilutris®-SEMENCOM, Brazil) + 20% egg yolk (MB). The treatments with CLA (CLA-Luta®-BASF, Brazil), which had oily presentation, were prepared from MB with addition of 1% sodium lauryl sulfate (MBL). The treatments were: positive control (CP) = MB, negative control (CN) = MBL; treatment 50 (T50) = MBL+50μM CLA; treatment 100 (T100) = MBL+100μM CLA and treatment 150 (T150) = MBL+150μM CLA. After thawing the semen, the characteristics were analyzed by CASA, and the integrity of plasma and acrosomal membranes and mitochondrial function of sperm by association probes PI, FITC-PSA, JC-1 and H-342. In both experiments there were no differences between treatments and the conjugated linoleic acid (CLA), at the concentrations used, had no effect on the integrity and superior functionality of spermatozoa that underwent cryopreservation. However, but in experiment 2, there were differences between individuals.

Full textMost irish monasteries of the middle ages have a round tower up to more than thirty metres high. The history of the monasteries at the beginning of christianity enables us to understand the context in which these towers (mentioned in irish annals as early as the middle of the tenth century) were built. The physical geography of ireland which to a large extent determines the history of the country, allows us to see how the round tower monasteries are distributed as well as the nature of the building materials which were required to erect the towers. Annals gibe the towers the name "cloigtheach", that is "the house of the bells". The tower thus had the function of a belfry, but could also be used as a shelter in the event of an attack as well as a place where the monks stored precious objects. The irish origin of the round tower, set in an ancient tradition of circular stone monuments, is undeniable. Nevertheless, the numerous exchange visits with the world of rome and byzantium via ravenna in particular, lead us to think that the round tower idea originates in italy. Whatever the truth of the matter, the "cloigtheach", from the nineteenth century onwards, has become one of the main symbols of ireland, inspiring as it does such a great variety of artists

Full textDue to climate change, the adaptation of bull breeds to environmental conditions becomes an important aspect for the expression of genetic potential. The objective of this study was to evaluate the reproductive performance of Braford bulls, through the Temperature and Humidity Index (THI) and its relationships with the seminal characteristics of bulls sustained in different climates of Brazil. Seventy-six Braford bulls (5/8 Hereford x 3/8 Nellore) were used, of six farms located in the cities of Rondonópolis (MT), Porto Nacional (TO) and Rio Verde (GO); Uruguaiana (RS), São Gabriel (RS) and Lages (SC). The seminal evaluation was performed four times at each location. Temperature and air humidity data were collected every hour from the automatic weather station at the National Institute of Meteorology. The THI was analyzed in the period of 30, 18 (spermiogenesis) and 12 days (epididymal transit) before seminal collection. The highest THI were observed in the summer of Uruguaiana (83.69) and in the rainy season of Rondonópolis (80.15) The lowest values of THI were observed in the autumn and winter of Lages (51.66 and 50.03), and in the rainy season of Rio Verde (72.05). In sperm quality, mass motion (MM), motility (M) and vigor (V) are lower in the winter of São Gabriel (2.87 ± 0.61; 60.60 ± 10.80 and 2.87 ± 0.51). The total defects were higher in Uruguaiana (21.42 ± 1.26). In Rio Verde, MM, M and V were lower (2.69 ± 0.17; 63.79 ± 4.01 and 2.69 ± 0.17) and higher percentages of major and minor defects (29.01 ± 3.24 and 16.02 ± 1.80). Motility showed a negative correlation with THI of 30 and 18 days (-0.121 e -0.163; P<0.01), while the total defects are positively correlated with all periods of THI (0.234; 0.207 and 0.198; P<0.01). Despite the high THI indexes, the sperm quality has not changed significantly to reject a bull during BBSE exam during all seasons, showing that Braford bulls are able of field service under different hot climates, as demonstrated by the THI.

A fertilidade dos reprodutores é de suma importância para a maximização das taxas de prenhez e melhoramento genético. O exame andrológico é uma importante ferramenta para a identificação de reprodutores sub férteis e para o monitoramento da qualidade seminal. Porém, poucas características do exame estão correlacionadas com a fertilidade in vivo. Assim, é fundamental a identificação de métodos que possam auxiliar na seleção mais precisa dos futuros reprodutores. Os objetivos do primeiro trabalho foram avaliar as acurácias e o viés das predições genômicas, utilizando diferentes métodos, para a característica perímetro escrotal ajustado à idade e ajustado à idade e peso em touros das raças Hereford e Braford. Os valores estimados para a herdabilidade apresentaram magnitude moderada a alta (0,39 a 0,48), demonstrando que é possível a obtenção de ganhos genéticos a partir da seleção. A predição de valores genéticos utilizando informações genômicas pelos métodos índice de seleção e single-step possibilitou o aumento de acurácia (em torno de 30%) para as características estudadas. Os ganhos de acurácia obtidos com os métodos, combinando as informações tradicionais com a genômica em relação ao método BLUP tradicional indicam que as predições genômicas podem ser usadas como ferramenta para melhorar os ganhos genéticos e reduzir o intervalo de gerações. Já o segundo artigo teve como objetivos: determinar a expressão de RNAm das paraoxonases (PON) 1, 2 e 3 no parênquima testicular, vesículas seminais e epidídimo de touros, avaliar a atividade de PON1 na circulação sanguínea e no plasma seminal; e correlacionar esta atividade com características avaliadas durante o exame andrológico. A caracterização da expressão dos genes foi realizada por qRT-PCR e a determinação da atividade de PON1 foi realizada em amostras de soro e plasma seminal provenientes de 110 touros. As PON 1, 2 e 3 foram expressas no parênquima testicular dos animais analisados. Observou-se uma correlação positiva entre a atividade sérica e seminal de PON1 com diversos indicadores de fertilidade.
Male fertility is important to optimize pregnancy rates and genetic improvement. Breeding soundness evaluations are key tools to identify sub fertile males and to survey characteristics of sperm quality. However, few sperm quality traits are correlated with fertility in vivo. Thus, it is essential to identify methods that can assist in more precise selection of future bulls. The goals of the first study were to evaluate the accuracy and the bias of the genomic predictions, using different methods, for the characteristic scrotal perimeter adjusted to age and adjusted to age and weight in Hereford and Braford bulls. The estimates for the heritability showed moderate to high magnitude (0.39 to 0.48), demonstrating that it is possible to obtain genetic gains from selection. The prediction of genetic values using genomic information by methods of selection index and single-step made possible the increase of accuracy (around 30%) for the characteristics studied. The gains in accuracy obtained with the methods, combining the traditional with the genomic information compared to traditional BLUP method indicate that the genomic predictions can be used as a tool to improve the genetic gains and reduce the range of generations. The second article had as its objectives: to determine the mRNA expression of paraoxonases (PON) 1, 2 and 3 in the testicular parenchyma, seminal vesicles, and epididymis of bulls, to evaluate the activity of PON1 in the bloodstream and in seminal plasma; and to correlate that activity with characteristics of breeding soundness. Characterization of gene expression by qRT-PCR and the determination of PON1 activity were performed in serum and seminal plasma from bulls 110. The PON 1, 2 and 3 were expressed in testicular parenchyma of the animals examined. There was a positive correlation between activity and serum PON1 seminal with different breeding soundness estimators.

The purpose of this experiment was to study the testicular morphologic parameters of the Crioula Lageana breed bulls, a breed that was threatened by extinction and, nowadays it is in recovery process through an association of creators. The experiment has developed with flocks of genetic preservation of the breed, linked to the Associação Brasileira de Criadores de Bovinos da Raça Crioula Lageana, located in Lages, Santa Catarina/Brazil. Sixty animals were evaluated with age between 18 and 144 months. The animals were divided in four treatments according to age: Treatment I, animals with 18 months of age; Treatment II, animals between 24 and 36 months of age; Treatment III, animals between 48 and 60 months of age; and Treatment IV, animals with 72 months or more. The researched parameters were: a) scrotal circumference (SC); b) length and testicular width; c) testicular volum and d) testicular form. Averages for the researched parameters were of 29,50 + 2,94; 33,68 + 2,52; 35,16 + 2,83 and 36,62 + 3,19cm for SC; 9,49 + 0,85; 10,79 + 1,00; 11,70 + 1,58 and 12,13 + 1,91cm for testicular length; 5,80 + 0,70; 6,47 + 0,58; 7,12 + 0,74 and 7,15 + 0,68cm for testicular width and 510,05 + 147,86; 720,96 + 181,82; 957,43 + 315,45 and 992,09 + 262,64cm³ for testicular volum, for groups I, II, III and IV, respectively. In relation to the format the moderate long way prevailed, followed by the moderate-oval, long and ovalspherical way, respectively with 60,83%; 30%; 7,5% and 1,67%. The largest increase in SC was observed in animals with age between 18 and 24 months. The testicles presented volume increase until five-years of age. The Crioula Lageana breed bulls showed dominance of testicles in the moderate long way, in all age groups. The appraised morphologic parameters indicate that the testicles of the studied bulls resemble each other to the described in zebuine animals and for synthetic breeds of crossings between taurine and zebuine
O projeto teve por objetivo estudar os parâmetros morfológicos testiculares de touros da raça bovina Crioula Lageana, uma raça que esteve ameaçada de extinção e hoje encontra-se em processo de recuperação através de uma associação de criadores. O experimento foi realizado nos rebanhos de preservação genética da raça, vinculados à Associação Brasileira de Criadores de Bovinos da Raça Crioula Lageana, localizados na região dos Campos de Lages, Estado de Santa Catarina, onde foram examinados 60 animais com idade entre 18 e 144 meses. Os animais foram agrupados em quatro tratamentos de acordo com a idade, sendo o Tratamento I formado por animais de 18 meses de idade, o Tratamento II por animais de idade entre 24 e 36 meses, o Tratamento III por animais com idade entre 48 e 60 meses e o Tratamento IV por animais com idade de 72 meses ou mais. Os parâmetros estudados foram: a) circunferência escrotal (CE); b) comprimento e largura testicular; c) volume testicular e d) formato testicular. As médias para os parâmetros estudados foram de 29,50 + 2,94; 33,68 + 2,52; 35,16 + 2,83 e 36,62 + 3,19cm para a CE; 9,49 + 0,85; 10,79 + 1,00; 11,70 + 1,58 e 12,13 + 1,91cm para comprimento testicular; 5,80 + 0,70; 6,47 + 0,58; 7,12 + 0,74 e 7,15 + 0,68cm para largura testicular e 510,05 + 147,86; 720,96 + 181,82; 957,43 + 315,45 e 992,09 + 262,64cm³ para volume testicular, respectivamente para os grupos I, II, III e IV. Quanto ao formato prevaleceu o longo-moderado, seguido do formato moderado-oval, longo e oval-esférico, respectivamente com 60,83%; 30%; 7,5% e 1,67%. O maior aumento na CE foi observado em animais com idade entre 18 e 24 meses. Os testículos apresentaram aumento de volume até os cinco anos de idade. O formato testicular mais freqüente em touros da raça Crioula Lageana é o longo-moderado em todas as faixas etárias avaliadas. Os parâmetros morfológicos avaliados indicam que os testículos dos touros da raça estudada assemelham-se aos descritos em zebuínos e raças sintéticas obtidas de cruzamentos de zebuínos e taurinos

Full textPerformance testing of young bulls are instruments of great utility in breeding programs and is aimed to evaluate the ability of individual animals regarding weight gain,, earliness, yield and carcass finishing, providing support for selection based on individual information of each animal. The objective of this study was to understand and define the relationships between genetic and quantitative genetic merit of Nellore bulls evaluated and their progenies in Performance Testing of Young Bulls(PTYB). In the present study, we analyzed the characteristics of weight calculated at 210 (W210), 365 (W365) and 450 days of age (W450), pre-weaning and post-weaning average daily gain (PREDG and POSTDG), scrotal circumference at 365 and 450 days of age (SC365 and SC450), ribeye area (REA) and carcass finishing (FIN) that were measured during the Weight Gain Tests (WET). The analyzed data set came from the Nellore participants in the Performance Testing of Young Bulls, which includes weight gain on pasture tests, from integrated crop and livestock production, coordinated by Embrapa Rice and Beans and Embrapa Cerrados. For data statistical analysis, we used statistical procedures available on the Statistical Analysis System (SAS) application and for obtaining (co)variance estimates, we used the Derivative-Free Restricted Maximum Likelihood method (DFREML), using univariate animal models and the Multiple Trait Derivative Free Restricted Maximum Likelihood (MTDFREML) application. Estimates of heritability for all traits showed moderate to high magnitudes. For direct and maternal additive effects, the heritability estimates were 0.37 ± 0.13 and 0.32 ± 0.15 and 0.35 ± 0.12 and 0.36 ± 0.16, for W210 and PREDG, respectively. As for W365, W450, POSTDG, SC365, SC450, REA and FIN, the additive heritability estimates were 0.33 ± 0.12, 0.53 ± 0.14, 0.54 ± 0.13, 0.36 ± 0.12, 0.54 ± 0.13, 0.26 ± 0.13 and 0.28 ± 0.14, respectively. Therefore, these results indicate the possibility of improving these characteristics by the use of breeding animals with superior genotype. Over the years there has been a significant entry of new bulls in evidence of weight gain on pasture, resulting in marked variation in predictions of genetic breeding values. However, there was positive and growing relationship between genetic value of bulls and their progeny. Thus, the results show that the selection of the best bulls based on genetic evaluations was efficient in terms of genetic progress.
Os testes de desempenho de touros jovens são instrumentos de grande utilidade em programas de melhoramento e tem como finalidade avaliar a capacidade individual dos animais para ganho em peso, precocidade, rendimento e acabamento de carcaça, fornecendo subsídios para seleção com base na informação individual de cada animal. Objetivou-se com esse estudo, conhecer e definir as relações genéticoquantitativas entre o mérito genético dos touros da raça Nelore avaliados e de suas respectivas progênies em Teste de Desempenho de Touros Jovens (TDTJ). No presente trabalho, foram estudadas as características de peso calculado aos 210 dias (P210), aos 365 dias (P365) e aos 450 dias de idade (P450), ganho médio diário pré desmame e pós desmame (GPPRE e GPPOS), perímetro escrotal aos 365 dias e 450 dias de idade (PE365 e PE450), área de olho de lombo (AOL) e acabamento de carcaça (ACAB) que foram mensuradas durante as Provas de Ganho em Peso (PGP). O conjunto de dados analisados foi proveniente dos animais da raça Nelore participantes do Teste de Desempenho de Touros Jovens que engloba as prova de ganho em peso a pasto, oriundos de sistemas de integração lavoura e pecuária, coordenado, pela Embrapa Arroz e Feijão e Embrapa Cerrados. Para analise estatística dos dados foram utilizados os procedimentos estatísticos disponibilizados no aplicativo Statistical Analysis System (SAS) e na obtenção das estimativas de (co)variâncias, empregou-se a metodologia da Máxima Verossimilhança Restrita Livre de Derivada (DFREML), por meio de modelos animal unicaráter, usando o aplicativo Multiple Trait Derivative Free Restricted Maximum Likelihood (MTDFREML). As estimativas de herdabilidade para todas as características apresentaram magnitudes moderada a alta. Para os efeitos aditivos diretos e maternais, as estimativas de herdabilidade foram 0,37±0,13 e 0,32±0,15 e 0,35±0,12 e 0,36±0,16, para P210 e GPPRE, respectivamente. Já para P365, P450, GPPOS, PE365, PE450, AOL e ACAB, as estimativas de herdabilidade aditiva foram 0,33±0,12, 0,53±0,14, 0,54±0,13, 0,36±0,12, 0,54±0,13, 0,26±0,13 e 0,28±0,14, respectivamente. Portanto, estes resultados indicam a possibilidade de melhoramento destas características por meio da utilização de reprodutores com genótipo superior. Ao longo dos anos houve expressiva entrada de novos touros em provas de ganho em peso a pasto, resultando na marcante variação das predições dos valores genéticos dos animais. Entretanto, houve relação positiva e crescente entre valor genético dos touros e de suas respectivas progênies. Sendo assim, os resultados demonstram que a seleção dos melhores touros baseados nas avaliações genéticas, tem sido eficiente em termos de progresso genético.

Full textEl turismo a nivel mundial ha crecido de manera exponencial en los últimos años, abriendo espacios para que se creen una serie de servicios para ayudar a satisfacer las necesidades dinámicas de los consumidores. Tomando en cuenta esta tendencia y la falta de actividades que existen para y lograr una visión global y fomentar la integración entre los alumnos chilenos y de intercambio de la Universidad de Chile se creó un proyecto que satisfaga ambas necesidades. Walk Up Santiago, consiste en realizar Free Walking Tours en el centro de Santiago, exclusivo para estudiantes chilenos y de intercambio de la Universidad de Chile, el cual en un comienzo tendrá una ubicación virtual. Los tours se realizarán en base a propinas, las cuales serán voluntariamente entregadas por los participantes de la actividad. Cabe mencionar que dentro de los objetivos específicos de la empresa, se encuentra desarrollar un proyecto sin fines de lucro que pueda autofinanciarse. Para el desarrollo del trabajo se utilizaron diversas herramientas dentro de las que podemos mencionar entrevistas, encuestas, participación en tours existentes, lecturas y análisis de distintas fuentes de información, estudio de tendencias, noticias de actualidad y una prueba piloto. Como resultado de las encuestas, se concluyó que alrededor del 77% de los alumnos, ya sean chilenos o extranjeros, están interesados en participar en este tipo de actividades. En segundo lugar, que al 35% de los estudiantes chilenos les gustaría participar como guía de esta actividad. Con el objetivo de evaluar el funcionamiento del tour y ver las observaciones de potenciales clientes, se realizó una prueba piloto. Esta actividad tuvo una duración de 2 horas aproximadamente y posibilitó testear: la ruta preseleccionada, las distintas actividades de interacción y los medios de difusión que se utilizaron. Al finalizar la prueba piloto se realizó una encuesta de satisfacción a los asistentes para recopilar sus opiniones acerca de los distintos ítems. Actualmente, existen 3 empresas en Santiago que se dedican a realizar free walking tours; Spicy Chile, Free Tour Santiago y Tour 4 tips. Estas empresas también funcionan en base a Walk Up Santiago: Free Walking Tour 2012 propinas. Los tours ofrecidos tienen una duración promedio de 4 horas y apuntan principalmente a extranjeros que visitan Santiago por poco tiempo. Se determinó que durante los tours y con el objetivo de lograr la integración entre los alumnos chilenos y extranjeros se idearon distintas actividades para que interactúen más entre ellos. Por ejemplo, se utilizarán stickers con los nombres de los asistentes, trivias, presentaciones personales (acerca de su lugar de origen, etc.), se creará un grupo en Facebook para que los integrantes puedan mantenerse en contacto entre ellos y con la empresa. La estrategia comunicacional se basará en la realización de un sitio web, flyers, tarjetas de presentación y alianzas estratégicas con diferentes empresas, como la Universidad de Chile y diferentes cafés del centro de Santiago, entre otras. Todo esto permitirá al público objetivo obtener información sobre las rutas, lugar de partida, los guías, horarios y fechas de los tours. Tomando en consideración los tours existentes y la investigación realizada sobre la competencia, se determinó que los guías a cargo de realizar los tours de Walk Up Santiago, serán alumnos de la Universidad de Chile, que se caractericen por ser extrovertidos, con capacidad de liderazgo de grupos y buen manejo del idioma inglés. Las postulaciones al cargo de guía se podrán realizar a través de distintos portales de búsqueda y el sitio web de la empresa. A su vez la empresa realizará charlas informativas en las distintas facultades para reclutar y motivar a los alumnos a ser parte de esta. Luego de ser seleccionados serán parte de una capacitación. Los tours realizados por Walk Up Santiago, tendrán una duración cercana a las 2 horas. Estos, podrán ser realizados en inglés o español según la preferencia de los asistentes y a partir del segundo año de funcionamiento, se llevarán a cabo todos los sábados en la mañana. Por otro lado, se determinó la importancia de la evidencia física en este negocio, el método de medición de calidad del servicio, la conducta esperada del cliente durante el tour, la forma en que se administrarán los empleados, las esperas, las contingencias, los errores y las quejas. Por último se hizo un análisis financiero en el que se determinó la rentabilidad del proyecto y la viabilidad de llevarlo a cabo. En este se obtuvo un valor actual neto (VAN) de $406.567 y una tasa interna de retorno (TIR) de 35%.

Full textA Campilobacteriose Genital Bovina (CGB) é considerada mundialmente como uma das principais causas responsáveis pela infertilidade de bovinos de carne criados sob regime extensivo. O agente etiológico é o Campylobacter fetus subespécie venerealis (Cfv), uma bactéria altamente adaptada ao aparelho genital bovino, transmitida durante a cobrição por touros portadores (hospedeiro reservatório da doença), e que provoca sucessivas mortes embrionárias na fêmea bovina, redução das taxas de gestação e aumento dos dias de intervalo entre partos. A aplicação dos novos métodos moleculares disponíveis para a pesquisa do agente Cfv, permitiu determinar a prevalência da CGB em amostras prepuciais de touros presentes na região do Alentejo. Recolheram-se amostras prepuciais de 29 touros, e a prevalência de touros infetados por Cfv foi de 20,7% (IC 95%: 0,098 – 0,384). Ao nível da prevalência por exploração, 4 em 10 explorações detiveram pelo menos um touro positivo (40%; IC 95%: 0,168 – 0,687). Assim, podemos concluir que a CGB pode certamente contribuir para a redução dos índices de produtividade das explorações de bovinos de carne no nosso país, sendo necessário estudar a dinâmica epidemiológica desta doença, elaborar medidas de prevenção e controlo, e aferir o impacto económico que representa para a rentabilidade e viabilidade da bovinicultura de carne nacional.
ABSTRACT - GENITAL CAMPYLOBACTERIOSIS IN BULLS UNDER EXTENSIVE FARMING CONDITIONS IN ALENTEJO - Bovine Genital Campylobacteriosis (BGC) is regarded worldwide as one of the main causes responsible for infertility in beef cattle raised under extensive farming conditions. The aetiological agent is Campylobacter fetus subspecies venerealis (Cfv), a bacteria highly adapted to the bovine genital tract, transmitted during service by carrier bulls (reservoir host), which causes successive embryonic deaths in females, reducing pregnancy rates and increasing the calving interval. The application of the new molecular methods available for identification of Cfv, allowed to determine the prevalence of BGC in preputial samples from bulls present in the Alentejo region. Preputial samples were collected from 29 bulls, and the prevalence of infected bulls with Cfv was 20.7% (95% CI: 0.098 – 0.384). Of the 10 farms analysed, 4 had at least one infected bull (40%; 95% CI: 0.168 – 0.687). Therefore, we can conclude that the BGC can certainly help to promote low levels of animal productivity in beef cattle farms in our country. It is necessary to study the epidemiological dynamics of this disease, develop prevention and control measures, and assess to the economic impact on profitability and viability of the national beef herds.

Full textThis work had the following aims: 1) to determine the bioeconomic impact of breeding soundness examination (BSE) in cow-calf systems in order to check its importance as management practice that can help improve a herd’s reproductive efficiency, 2) to quantify the variation in scrotal circumference, the effects of age and breeds and to investigate the relationships between testicular weight (TW), scrotal circumference (SC) and live weight (LW) in bulls. The results suggest that SC in young bulls is the best way to estimate TW and, therefore, a useful tool for the selection of bulls, 3) to quantify the reasons for the culling of beef bulls in the state of Rio Grande do Sul, Brazil, based on the BSE. A total of 30,700 bulls were assessed by the Bull Evaluation Program (BEP) between 2001 and 2004. Of this total, 17.12% were culled, and among the culled bulls, the general clinical examination, semen analysis and behavioral assessment showed similar culling rates (4.59, 4.54 and 4.29% respectively), contrasting with the results obtained by the special clinical examination (6.80%). The work consisted of three articles: 1) Bioeconomic impact of bull breeding soundness examination in cow-calf systems, 2) Measurement of scrotal circumference in beef bulls in Rio Grande do Sul, Brazil and 3) Reasons for the culling of beef bulls in breeding soundness examination in the state of Rio Grande do Sul, Brazil. The first article concluded that BSE is a low-cost management practice and an important technological alternative that aids in increasing the profitability of cow-calf production In the second article, the conclusion is that the results obtained in the two experiments show the importance of measuring SC in bulls, as this measurement can be made as soon as a bull enters puberty. The last article concluded that aging increases the probability of bull culling, and examinations lacking any stage of the breeding soundness assessment cause inapt bulls to remain in cow-calf herds.

O objetivo do presente experimento foi estudar os efeitos da heterose sobre a idade e peso corporal à puberdade e à maturidade sexual, os parâmetros reprodutivos durante as fases pré-puberal, puberal e maturidade sexual, bem como a interferência de diversas composições genéticas na caracterização dos estádios de maturação sexual em animais compostos Montana Tropical. Utilizou-se 140 touros, sendo 12 adaptados e 128 Montana Tropical que formavam 8 grupos de diferentes composições genéticas. Os animais foram criados em condições de pastagens com suplementação no período de maio até julho de 1999, posteriormente os mesmos foram confinados durante o período de 02/08 a 07/12/99, quando então passaram a ser manejados somente em regime de pastagem. O período experimental compreendeu a idade média de 11,5 a 17,5 meses. A puberdade e a maturidade sexual foram determinadas por meio de características ponderais e características físicas e morfológicas do sêmen. A puberdade foi alcançada em média aos 12,70±1,62 mês de idade, quando os animais pesavam 349,24±49,40 kg. Neste período os animais apresentaram perímetro escrotal (pe) de 28,71±2,60 cm, volume do ejaculado (vol) de 9,31±3,37 ml, turbilhonamento (turb) de 0,18±0,48 (0-5), motilidade espermática progressiva (mot) de 52,52±15,20 %, vigor (vig) de 2,41±0,74 concentração espermática no ejaculado (cejac) de 489±898,10, (0-5), defeitos espermáticos maiores (dm) de 54,12±28,42 %, defeitos espermáticos menores (dmen) de 27,67±17,60 % e defeitos espermáticos totais (dt) de 81,80±28,04 %. Não houve diferença (P<0,05) entre os animais dos diferentes grupamentos genéticos. A maturidade sexual foi alcançada em média com 13,83 ± 1,58 mês de idade, quando os animais apresentavam peso de 369,91 ± 45,74 kg, pe de 30,12±2,63 cm, vol de 9,39±4,20 ml, turb de 0,86±1,12 (0-5), mot de 62,16±13,98 %, vig de 3,10±0,84 (0-5), cejac de 1582,01±1726,91, dm de 9,95±4,84 %, dmen de 8,90±4,10 % e dt de 18,85±7,04 %. Estes resultados demonstram efeito positivo da heterose sobre a precocidade sexual e desenvolvimento ponderal dos animais e a homogeneidade do grupo, apesar das diferentes composições genéticas. Não houve diferença de médias registradas para características estudadas entre os animais dos diferentes grupamentos genéticos (P>0,05), com exceção das médias para defeitos espermáticos maiores, que diferiram (P<0,05) na ocasião da maturidade sexual.
The aim of this study was to verify heterosis effects on age and weight at puberty and sexual maturity, catacterize reprodutive aspects during pre puberal, puberal and sexual maturity phases and verify different genetic compositions effects on sexual maturity phases in Montana Tropical composite cattle. This experiment was realized with 140 bulls, being 12 adapted and 128 Montana Tropical ones, distributed in 8 groups of different genetic composition. Animals were raised under pasture and supplementation during May, 1999 to July 1999. After that, they were confined from 02/08 to 07/12/1999. After that they were raised only under pasture. The experimental period was comprehended between 11,5 to 17,5 months of age. Puberty and sexual maturity were determined by growth traits and phisical and morphological semen traits. Puberty was reached around 12,7+1,62 months of age, when animals weight was 349,24+49,40 Kg. In this period, animals’ scrotal perimeter (pe) was 28,71+2,60 cm, semen volume (vol): 9,31+3,37 ml, turbilhonamento (turb): 0,18+0,48 (0-5), sperm progressive motility (mot): 52,52+15,20%, vigor (vig): 2,41+0,74 (0-5), sperm concentration per ejaculates (cejac): 489+898,10, major sperm deffects (dm): 54,12+28,42, minor sperm deffects (dmen): 27,67+17,60 and total sperm deffects (dt):81,80+28,04%. There was no difference (P<0,05) among genetic groups. Sexual maturity was reached around 13,83+-1,58 months of age, when body weight was 369,91+45,74 kg, pe: 30,12+2,63 cm, vol: 9,39+4,2 ml, turb: 0,86+1,12 (0-5), mot: 62,16+12,98%, vig: 3,10+0,84 (0 -5), cejac: 1582,01+1726,92, dm: 9,95+4,84%, dmen: 8,90+4,10% and dt: 18,85+7,04%. These results show the positive effects of heterosis on sexual precocity and growth on these animals and on homogeneity of the group , instead of the different genetic compositions. There was no differences on the averages for the traits analysed among the genetic groups (P>0,05), except for the averages for major sperm deffects, that were different (P<0,05) at sexual maturity.

Apresenta um olhar propondo o uso do Walking Tour (WT) como forma de preservação da história e do patrimônio de uma cidade, inserindo-o como uma ferramenta de motivação, consciência e conhecimento, em escolas, associações e grupos organizados, podendo dessa maneira estimular a identidade entre cidadão e cidade. O uso do WT como instrumento pedagógico aparece no trabalho como um eficaz recurso educacional do professor para despertar no aluno a curiosidade necessária acerca de sua cultura e sua cidade. O trabalho propõe ao mesmo tempo a utilização do WT no turismo cultural como argumento ao guia de turismo e como forma de gerar trabalho, divisas e melhorias para a economia local.

As dietas enriquecidas com fontes de ácidos graxos poliinsaturados (AGPs) para touros jovens no período da puberdade a maturidade sexual podem exercer efeito positivo no desempenho reprodutivo. Além disso, selecionar animais jovens de melhor eficiência alimentar (baixo consumo alimentar residual - CAR) é muito importante para os programas de melhoramento genético. Dentro desse contexto, o objetivo do presente estudo foi avaliar os parametros reprodutivos de machos jovens da raça Nelore de baixa e alta eficiência alimentar suplementados com ácidos graxos (AGs) protegidos em regime de pastagem. Foram utilizados 48 machos jovens com média de 14,3±0,13 meses de idade e peso de 389,5±5,43 kg. O delineamento experimental foi inteiramente casualisado em arranjo fatorial 2 x 2 (CAR x suplementação) sendo, 24 animais baixo ou negativo CAR com ou sem suplementação com AGs e 24 alto ou positivo CAR com ou sem suplementação com AGs. As dietas experimentais foram isoproteicas. O período de suplementação foi de dezembro à outubro. Os animais foram mantidos em pastagem de capim-marandu, em lotação contínua e taxa de lotação fixa. As mensurações de características de crescimento, de consumo alimentar, concentrações plasmáticas de metabólitos e hormônios, avaliação andrológica e ultrassonografia testicular foram realizadas a cada 28 dias, dos 14 aos 24 meses de idade. A criopreservação espermática foi realizada na última colheita, momento em que os animais apresentavam 24 meses de idade. Após descongelação foram realizados avaliações computadorizadas da cinética espermática (CASA), teste de termorresistência rápido (TTR), integridade da membrana plasmática e acrossomal e produção in vitro de embriões (PIVE). Os dados foram analisados pelo procedimento PROC MIXED do SAS. Os touros de baixo CAR apresentaram peso corporal inicial maior (398,0±5,4) do que os de alto CAR (380,9±5,4) e mantiveram a diferença durante todo o experimento (P<0,05). Os animais que receberam suplementação com AGs protegido apresentaram maiores concentrações plasmática de colesterol, lipoproteína de alta densidade (HDL) e testosterona (161,5±3,2 ng/dL, 67,2±1,6 ng/dL e 12,2±0,6 ng/mL, respectivamente) em relação aos tratamentos sem AGs (124,5±3,2 ng/dL, 57,9±1,6 ng/dL e 10,5±0,6 ng/mL, respectivamente) (P<0,05). Não foram observadas diferenças entre os tratamentos para consumo alimentar, ecotextura testicular, análise do sêmen fresco e PIVE (P>0,05). No entanto, para a avaliação do sêmen pós-descongelação, as velocidade espermáticas (VAP - de trajeto, VSL - em linha reta e VCL - curvilinear; µm/s) analisadas pelo CASA foram maiores para os touros suplementados com AGs protegido (82,6±1,6, 68,6±1,2 e 132,0±3,2 para VAP, VSL e VCL, respectivamente) em relação aos que receberem suplementação sem AGs (76,2±1,6, 64,2±1,2 e 122,3±3,2; VAP, VSL e VCL, respectivamente) (P<0,05). Apesar dessas diferenças de velocidade espermática, coleterol e testosterona sanguínea são necessários avaliações em conjunto com outros testes reprodutivos para determinar a real influência dos AGs na qualidade espermática.
Diets enriched with sources of polyunsaturated fatty acids (PUFAs) for young bulls from puberty to sexual maturity may have a positive effect on reproductive performance. In addition, selecting young animals with better feed intake (low residual feed intake - RFI) is very important for breeding programs. Thus, the aim of this study was to evaluate the reproductive parameters of young Nelore bulls of low and high feed intake supplemented with PUFA in the pasture. The total of 48 young males were used with a 14.3±0.13 months of age and a weight of 389.5±5.43 kg. The experimental design were completely randomized in a factorial 2 x 2 (RFI x supplementation) being 24 animals high RFI with or without supplementation with PUFA and 24 animals low RFI with or without supplementation with PUFA. The diets were isoproteic. The supplementation period was from December to October and the animals were kept in Brachiaria brizantha cv. Marandu pasture in continuous stocking during the experimental period. The measurements of growth characteristics, feed intake, plasma concentrations of metabolites and hormones, andrological evaluation and testicular ultrasonography were performed every 28 days, from 14 to 24 months of age. Sperm cryopreservation was performed it the last collections, at which time the animals were 24 months old. After thawing, computer aided semen analysis (CASA), rapid thermoresistance sperm tests (TTR), integrity of the plasma membrane and acrosomal and in vitro embryo production (IVEP) were performed. The data were analyzed by the SAS procedure PROC MIXED. The low CAR bulls have had higher initial body weight (398.0±5.4) than high CAR (380.9±5.4) and maintained the difference throughout the experiment (P<0.05). The animals that received supplementation with PUFA had higher plasma concentrations of cholesterol, high density lipoprotein (HDL) and testosterone (161.5±3.2 ng/dL, 67.2±1.6 ng/dL e 12.2±0.6 ng/mL, respectively) in relation to treatments without PUFA (124.5±3.2 ng/dL, 57.9±1.6 ng/dL e 10.5±0.6 ng/mL, respectively) (P<0.05). No differences were observed between treatments for feed intake, testicular ecotexture, analysis of fresh semen and IVEP (P>0.05). However, sperm evaluation after thawing, the spermatic velocities (VAP - average path velocity, VSL - straight linear velocity and VCL - curvilinear velocity; μ / s) analyzed y CASA were hi her for bulls supplemented with PUFA (82.6±1.6, 68.6±1.2 e 132.0±3.2 para VAP, VSL e VCL, respectively) in relation for bulls without PUFA (76.2±1.6, 64.2±1.2 e 122.3±3.2; VAP, VSL e VCL, respectively) (P<0,05). Despite these differences in sperm velocity, coleterol and testosterone evaluations are needed in conjunction with other reproductive tests to determine the actual influence of PUFA on sperm quality.

Full textAt the end of Antiquity, the site of Tournus is occupied by a small fortified settlement along the Saône, traversed by the Via Agrippa. After 875, its centre of gravity shifts ca. 500 m to the site of an oratory dedicated to the martyr-saint Valerian, becoming the centre of a Benedictine abbey dedicated to Saint Philibert. Protected from the powerful and richly endowed, the monastery acquires jurisdiction over the surrounding territory and its inhabitants. In its shadow a borough gradually develops that absorbs the former castrum. Assembling the written sources but above all the archaelogical evidence, this study begins by assessing the remains of the Antique castrum and the evolution of the site during the Early Middle Ages. There follows an analysis of the abbey site and the Medieval town, tracing their development form the 11th to the 14th century thanks to the remarkable remains of religious and civil architecture preserved in elevation and observed in occasional excavations. These two elements are presented together by successive major phases -more fully for the abbey, owing to the greater density of information relating to this site. Dating is based on intersecting criteria, particularly the development of construction techniques, and the function of the different spaces is examined for each phase. On the whole, this joint development of abbey and town at first reveals a strong monastic impetus, provoked by an identifiable reforming zeal in the 11th century and later by the power of the abbey in the 12th and 13th centuries. However, from the second half of the 13th century, a different dynamic affirms itself, more properly secular and urban

Full textThe manufacture de la soierie (silk fabrics) in tours was created by the will of king louis the eleventh in fourteen seventy. Its early stages were difficult. But it became prosperous and knew till fifteen forty a real golden age. Lyon as the gate to the italian market of silk fabrics had obtained letters patent in fifteen thirty five for its manufacture. Its situation and the obligation to go through it for the foreign silks entering in france ensured lyon a powerful precedence on tours. The latter then knew an implacable competition aggravated by a conjuncture of religious wars, civil wars, epidemics and financial crises. The war against holland, disappointing and expensive for the king of france also caused bankruptcies in the industry and the trade for the manufacture of tours. The home and foreign policy of the sun king completed the ruin of the vital forces of the country and more particularly those of the manufacture of tours. Unemployment and poverty had serious and dramatic consequences on the firm which however thanks to its tradition of more than two hundred years did not disappear in the seventeenth century
Hardy, Seguin Mireille. "Paul Auster : tours et détours du fictif." Paris 3, 1996. http://www.theses.fr/1996PA030186.
Full textThis study aims at exploring the different tours and detours that suffuse paul auster's fiction, hinging on the polysemy of the french word "tours" : towers, surrounding walls, tricks, twists. Detours or diversions lead to a final turn of the screw, looping the loop, forcing the text back to its beginning and questioning what has just been asserted. Both key figures - the tower of babel and the labyrinth - build the text on images of confusion and urge it to an impossible logic of (no)-return. The tower, both landmark and origin of disorder, holds a central and ambiguous position, and so does the grid-pattern that fences space in, turning it now into a prison, then into a place of redemption and rebirth (the room). Since they are denied stability, the landmarks that appear successively as new york skyscrapers, a grotesque wall, the statue of liberty, or the moon are alternately being built and unbuilt. Likewise, the quest for pre-babelian language, which is felt as essential, turns out to be impossible. The text constantly winds about, as palimpsestuous detours, labyrinths, diversions, or even perversions of time and space and mirror images drag it out of its tracks, lead it astray, destabilize it. The traditional narrative is repeatedly questioned, weighed down with doubts and double tropisms that condemn it to an impassable ambiguity keep it locked inside itself. Fluctuations, shifts in meaning, absence of the author, secrets and lies all build up to paradoxes that make the reader feelgiddy and deprive him of all certainties. Entropy and the constant obliteration of tracks seem to drag the text towards an inflexible conclusion which never comes: the voice of the text gets lost somewhere between the end and the new beginning

A raça Nelore é a principal raça utilizada na pecuária brasileira, sendo a de maior rebanho comercial do mundo. Com a utilização das técnicas reprodutivas, principalmente a inseminação artificial, torna-se importante estimar parâmetros genéticos para as características reprodutivas de touros, a fim de elucidar mais as características e vislumbrar a possibilidade de sua inclusão como critério de seleção. Ao todo 17 características divididas em características biométricas do testículo, características físicas e morfológicas do sêmen e características vesiculares tiveram seus parâmetros genéticos estimados neste trabalho para uma população de touros Nelore com idade de 18 a 36 meses. Utilizou-se o modelo animal uni e bi característico para a estimação dos componentes de (co)variância. O grupo de contemporâneos foi considerado como efeito fixo e a idade como co-variável. Dentre as estimativas de herdabilidade, é importante ressaltar que perímetro escrotal, característica biométrica mais avaliada em touros, apresentou herdabilidade de 0,47, sendo esse valor similar ao encontrado para todas as outras características biométricas (0,34 a 0,48). Já dentre as características físicas e morfológicas, houve maior discrepância entre as estimativas de herdabilidade encontradas (0,05 a 0,49) e, dentre elas, é pertinente destacar a motilidade espermática (0,07) que afeta diretamente a fertilidade do touro e as características morfológicas, defeitos espermáticos maiores, menores e totais (0,49, 0,17 e 0,39). Em relação as correlações genéticas estimadas, nota-se correlação alta e favorável entre as características biométricas do testículo, sugerindo que apenas uma delas pode ser usada como critério de seleção. Entre todas as características, pode-se observar correlações variando de baixas a altas, porém sempre favoráveis. Assim, os resultados evidenciam que a escolha do perímetro escrotal como critério de seleção para fertilidade de machos é bastante acertada, por provocar mudanças favoráveis nas características de qualidade do sêmen.
Nelore is the main breed used in Brazilian cattle production, being the largest commercial herd in the world. The use of reproductive techniques, especially artificial insemination, increase the importance of genetic parameters estimation for bull’s reproductive traits. Genetic parameters increase the knowledge about the trait and provides information about their use as selection criteria. Seventeen traits divided into testis biometry, physical and morphological semen traits and vesicular traits had their genetic parameters estimated in this study for a Nelore bulls population aged 18 to 36 months. Single and multi-trait animal models were used to estimate (co)variance components. Contemporary group was used as fixed effect and age as a co-variable. Among the estimates of heritabilities, it is important to emphasize that the scrotal circumference, which is the most frequently biometric trait evaluated in bulls, had heritability of 0.47. This value was similar to the findings for all other biometric traits (0.34 to 0.48). Among the physical and morphological traits, there was high variability between heritability estimates (0.05 to 0.49). Among them, it can be highlighted the sperm motility heritability (0.07), which is a trait that directly affects the bull fertility. Across semen morphological traits, the major, minor and total sperm defects exhibited heritability 0.49, 0.17 and 0.39, respectively. The genetic correlations were high and favorable between biometric testis traits. This result, suggest that only one trait can be used as a selection criterion. The genetic correlations between all traits varied from low to high, but they were favorable. Thus, the results show that the scrotal circumference is an appropriate selection criteria for male fertility, since it can cause favorable changes in semen quality traits.

Full textThe high retention capacity of peat can be used to purify wastewaters before their release into the environment. Industrially, this capacity is used in a process called "Jardin Filtrant{\text{TM}, developed by the Phytorestore company. In this process, wastewaters are filtered through pots, filled with carex (CP) and sphagnum (SP) peat and vegetated with wetland plants, such as Phragmites australis (P. A. ). The purpose of this research project was to improve the efficiency of the process through understanding the mechanisms of retention of copper on peat particles and the interface peat / root. These interactions are known to influence the mobility and bioavailability of ET. Three approaches have been implemented. The chemical approach (titrations and adsorption isotherms) showed that SP has a higher reactivity CP in terms of proton exchange (QH,tot= 3. 88 vs. 3. 64 mmol/g) than the affinity for copper (log KCu,COOH}= 1. 71 vs. 1. 30). The approach spectroscopic (EXAFS and XANES) showed that for levels between 100 and 300 ppm Cu form a predominantly double chelate five atoms of the type Cu (malate) 2 with mixed groupings-OH R-COOH. At higher levels, it is complexed by the dicarboxylic groups R-COOH and-COOH form a chelate six atoms of the type Cu (malonate). The micro-spectroscopy (μ-EXAFS and μ-XANES) showed that the two previous complexes predominate in the locker peat. Rhizosphere criminal also contains grains of brass and organo-mineral aggregates of nanocrystalline copper metal. The former are of anthropogenic origin and biological seconds
