13. In-vitro screening of Kalahari browse species for rumen methane mitigation
The nutritional value of browse foliage from the Thorny Kalahari Dune Bush veld of South Africa is not characterized. Most of this browse species is rich in tannin, but still palatable, and is consumed by ruminants during the dry season, as well as having a role to play in mitigating enteric methane emission from ruminants. In this study, the rumen methane m

14. Oestrus ovis infection of grazing sheep during summer in southern Chile
Abstract: Oestrus ovis is a botfly whose larvae cause nasal myiasis, an environmental-dependent disease in small ruminants, generating acute and chronic injuries in the cranial cavities of sheep. Chile is a country of the southernmost worldwide distribution of this parasite, and there is few information about. Whence, the objective of this study was to appr

15. Models for estimating feed intake in small ruminants
This review deals with the most relevant limits and developments of the modeling of intake of sheep and goats reared intensively and extensively. Because small ruminants are normally fed ad libitum, voluntary feed intake is crucial in feeding tactics and strategies aimed at optimal animal production. The effects of genetic, neuroendocrine, hormonal, feed and

16. Histopathological and molecular characterization of encephalitic listeriosis in small ruminants from northern Paraná, Brazil
Listeriosis is a disease primarily of ruminants caused by the Gram-positive bacterium Listeria monocytogenes. Ruminants either demonstrate manifestations of the encephalitic, septicemic, or reproductive form of listeriosis. The pathological and molecular findings with encephalitic listeriosis in a 5.5-month-old, male, mixed-breed goat and a 3-year-old Texel-

17. Comparative analysis of agr groups and virulence genes among subclinical and clinical mastitis Staphylococcus aureus isolates from sheep flocks of the Northeast of Brazil
Staphylococcus aureus is one of the most frequent mastitis causative agents in small ruminants. The expression of most virulence genes of S. aureus is controlled by an accessory gene regulator (agr)locus. This study aimed to ascertain the prevalence of the different agr groups and to evaluate the occurrence of encoding genes for cytotoxin, adhesins and toxin

18. Colostro bovino liofilizado como substituto do colostro caprino e o desenvolvimento do epitélio intestinal de cabritos durante o período de aquisição de proteção passiva / Lyophilized bovine colostrum as a substitute of goat colostrum and the intestinal epithelium development of goat kids during the period of passive protection acquisition
O presente projeto teve como proposta estudar a utilização do colostro bovino liofilizado como manejo alternativo para caprinos recém-nascidos. Estudos relacionados com a aquisição de proteção passiva e o desenvolvimento do epitélio intestinal, como aspectos citológicos e histológicos, atividade celular e expressão do receptor específico para o I

19. AVALIAÇÃO DE COMPONENTES DA FIBRA COMO MARCADORES INTERNOS E DE ALCANOS PARA ESTIMAR O FLUXO DE DIGESTA NO DUODENO DE BOVINOS / EVALUATION OF FIBER COMPONENTS AS INTERNAL MARKERS AND ALKANES FOR DUODENAL DIGESTA FLOW ESTIMATION IN CATTLE
The use of ADF as internal Marker of duodenal digesta flow was evaluated, for this the intestinal degradability of fiber was studied. Four Holstein calves (156 33 kg), fitted with duodenal cannula T simple, and one calve fitted on the rumen, fed diet base with black oat and supplement, was used. Seven feeds were weighted on the polyester bags (7x5,5cm; 25

20. Morphometry and carcass characteristics of goats submitted to grazing in the Caatinga
The objective of this study was to evaluate morphometric measures, carcass yields, absolute weights and yields of commercial cuts of carcass of kids with no defined breed. Eighteen castrated male goats, with average weight of 15 kg were used. The experimental period lasted 105 days. The experimental design was completely randomized; animals were allocated to

21. Estudo molecular de pestivirus em amostras de cultura celular e soro de pequenos ruminantes. / Estudo molecular de pestivirus em amostras de cultura celular e soro de pequenos ruminantes.
The Ruminants Pestiviruses are often associated with temporary and subclinical or mild clinical signs, with the largest losses related to the infection of pregnant females that can cause fetal loss and birth of persistently infected (PI) animals. The Pestivirus are distributed in many countries, including Brazil, where studies in goats and sheep are scarce.

22. Estudo clínico-epidemiológico da urolitíase obstrutiva em caprinos e ovinos. / Clinical-epidemiological study of obstrutive urolithiasis in sheep and goats.
Considerando-se a importância clínica e econômica da urolitíase obstrutiva para a produção de pequenos ruminantes, objetivou-se desenvolver um estudo dessa enfermidade em caprinos e ovinos. Para tanto, utilizou-se dados dos prontuários de 62 animais atendidos no período de 2001 a 2011, considerando-se variáveis epidemiológicas, clínicas, urinális

23. Efeito da substituição do feno de capim Tifton (Cynodon ssp) por casca de mamona (Ricinus communis) em dietas a base de palma forrageira (Nopalea cochenilifera Salm Dick) sobre o perfil de metabólitos energético-protéicos e mineral em ovinos. / Effect of replacement tifton hay Cynodon spp) for castor beans hulls Ricinus communis) based diets of spineless cactus (Nopalea cochenilifera Salm Dick) metabolites on the profile of mineral and energy-protein in sheep.
Avaliou-se perfil metabólico de ovinos recebendo dietas a base de palma forrageira (Nopalea cochenilifera Salm Dick) com diferentes níveis de casca de mamona (Ricinus communis) em substituição ao feno de tifton. Foram utilizados 28 carneiros adultos, inteiros, sem padrão racial definido, com peso vivo médio inicial de 18 kg. Amostras de sangue foram co
