13. Concentrate supplementation during pregnancy and lactation of ewes affects the growth rate of lambs from a variety of crosses
The objective of this study was to determine how concentrate supplementation during late third gestation and lactation affects ewe and offspring performance from birth to weaning. Thirty-six ewes and their offspring (n = 32) were used. Eighteen Morada Nova and 18 Santa Inês ewes were artificially inseminated with semen from Dorper ram and distributed in a c

14. 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-

15. Phenotypic and genotypic characterization of lactic acid bacteria isolated from cow, ewe and goat dairy artisanal farmhouses
Lactic acid bacteria collected from artisanal farmhouses were characterized using a polyphasic approach. Phenotypic methods including biochemical assays, ribosomal DNA restriction analysis and 16S rDNA sequence analysis were performed. This approach provides accuracy for identification, and helps to avoid the loss of natural biodiversity including potentiall

16. Produção, composição do leite e desempenho reprodutivo de ovelhas Santa Inês alimentadas com rações contendo óleo de canola ou linhaça / Milk yield, milk composition and reproductive performance of Santa Inês ewes fed diets containing canola or linseed oil
The objective in this study was to evaluate the effect of the addition of canola oil (CO) or linseed oil (LO) on milk production and composition and reproductive performance of Santa Inês ewes. In the experiment I, 33 Santa Inês ewes were fed diets containing 50% of roughage (Cynodon dactylon hay). Experimental diets included a control (no oil) and two rem

17. Effects of GnRH administration on ovulation and fertility in ewes subjected to estrous synchronization
The objective of this study was to verify the effects of GnRH on ovulation and pregnancy of ewes subjected to a short-term synchronization of estrus. Santa Inês and crossbred Santa Inês/Dorper ewes received 60 mg MAP sponges during 6 days plus 300 IU eCG and 30 µg d-cloprostenol 24 h prior to sponge withdrawal (SW). Ewes were assigned to receive 0.9% NaCl

18. Fungos aeróbios no intestino grosso de borregos e de ovelhas criados em pastagens tropicais
Fungi populations were evaluated in large intestine from sheep raised in the North of Minas Gerais, Brazil. The samples were from 39 Santa Inês crossbred ewes and 30 lambs raised on Tanzania grass (Panicum maximum cv. Tanzania), both supplemented with mineral mixtures. The clinical specimens were directly collected from rectal ampoule with sterile swabs. Th

19. Isolamento, enumeração, identificação molecular e avaliação de propriedades probióticas de bactérias ácido-lácticas isoladas de leite de ovelha
Sheep milk, obtained from one of the oldest domestic animals, is unique for its high solids ratio. Its cheese are more famous than the milk itself. Lactic acid bacteria, abundant in milk from several mammals, include most of the probiotic microorganisms, which bring benefits to their consumers when ingested in viable and adequate portions. Few data are avail

20. Selection objectives and criteria for sheep in Central Brazil
Three production systems for sheep (Low - L, Medium - M and High - H technology), with increasing technological levels, were studied under conditions in the Center-west of Brazil, to determine economic weights and selection indices of important traits. Receipts and costs were simulated using an economic simulator to calculate the structure of the operational

21. Age at First Mating on Lifetime productivity of Corriedale Ewes in Southern Brazil.
A total of five different Corriedale flocks (respectively initiated in years 1976--1980), totalling 2,561 breeding ewes, were first mated at 19-20 or 30-31 months of age. Lifetime production data on: a) fleece weight and its components (as measured by greasy fleece weight, washing yield, clean fleece weight, fibre diameter and staple length), b) reproductive

22. Potencial probiótico de bactérias lácticas e atividades biológicas de leite e queijos de ovelha / Probiotic potential of lactic bacteria and biological activities of ewe´s milk and cheeses
Bactérias lácticas probióticas e peptídeos bioativos são importantes componentes de alimentos funcionais. Neste trabalho, bactérias lácticas isoladas de leite ovino cru e de queijo de ovelha foram identificadas por 16S rDNA como pertencentes ao gênero Lactobacillus e avaliadas quanto ao potencial probiótico. Todas as linhagens demonstraram adequada

23. Pattern of Change in Wool Production From Corriedale Breeding Ewes Varying in Age Composition in Rio Grande do Sul, Brazil.
The effects of age and reproductive status on the main wool production components of 1256 Corriedale breeding ewes, ageing 21/4 to 81/4 years old, were investigated in southern Brazil, and used to predict the mean production of flocks of differing age structure. The results showed that wool production varies considerably with age and reproductive status and

24. Efeito da presença de um coespecifico no alojamento de ovelhas em novo ambiente, após estresse agudo causado pelo transporte / Effect of the presence of a conspecific in the housing of sheep in the new environment, following acute stress caused by transportation
Background: Sheep are social and gregarious animals. They feel at ease when free and clustered rather than isolated. In some situations, as in experimental procedures, they need to be separated from the flock and kept without social company. Both instances, separation from the flock and isolation are considered stressful and may impact their well being. As s
