3. The effect of organic selenium in feeding of ewes in late pregnancy on selenium transfer to progeny
ABSTRACT The objective of this study was to determine the effect of supplemented organic selenium at different levels to concentrate feed of Norduz ewes in late pregnancy on maternal serum, placenta, colostrum, and offspring serum concentrations. This study was conducted using two-year-old 35 Norduz ewes. Ewes were randomly assigned to one of three dietary t

4. 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

5. 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

6. 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

7. 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

8. 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

12. Effects of growing rates in prepubertal period on performance, age at puberty and milk yield of Santa Ines sheep / Efeitos de diferentes taxas de crescimento na recria sobre o desempenho, idade a puberdade e produção leiteira em fêmeas da raça Santa Inês
Trial I: Sixty Santa Ines ewe lambs were used to evaluate the effects of three growing rates until 7 months of age. Treatments were defined to achieve high (HGR), moderate (MGR) and low (LGR) growing rates. The dry matter intake and average daily gain (ADG) were evaluated, well as serum levels of progesterone in order to detect the age of puberty. Linear eff
