1. Echotextural characteristics of the mammary gland during early lactation in two breeds of sheep varying in milk yields
Abstract The main goal of this preliminary study was to determine and compare ultrasonographic characteristics of the mammary gland in two genotypes of ewes varying in milk productivity at 2, 3 and 4 weeks after lambing. Ultrasonographic images of the udder were obtained using the 5.0- and 7.5-MHz transducers, in axial and coronal planes, in four low milk-yi

3. Performance and serum cortisol concentration in Santa Inês lambs under different suckling schemes
ABSTRACT The objective of this study was to examine the effects of suckling schemes (continued, controlled, and total separation) and the type of pregnancy on performance and serum cortisol concentration in lambs. A total of 29 Santa Inês ewes and 40 lambs were used, and the randomized block design was applied in a split-plot scheme with a 3 × 2 factorial

4. Early weaning and concentrate supplementation strategies for lamb production on Tifton-85 pasture
The influence of early weaning and concentrate supplementation strategies on sward characteristics, forage chemical composition and lamb productivity were evaluated in four production systems on Tifton-85 pasture: suckling lambs not supplemented until slaughter; suckling lambs supplemented with concentrate in creep feeding until slaughter; early-weaned lambs

5. Effect of breed (wool and hair) and sex on the carcass quality of suckling lambs under intensive management
Carcasses of twenty lambs (10 males and 10 females) from the Canaria Hair breed (CHB) and another twenty (10 males and 10 females) from the Canaria breed (CB) of 9.91±0.73 kg and 9.87±0.80 kg live weight, respectively, were studied. In the principal component (PC) analysis, the projection of carcass measurement data in the first PC allowed for clearly dist

9. Parâmetros produtivos e comportamentais de ovelhas e cordeiros submetidos à restrição energética
The objective of this work was to evaluate the influence of feeding energy levels during the last third of gestation and lactation on productive and behavioral parameters of ewes and its lambs. The experiment was carried out in the sheep raising sector at the Farm School of UEL from August to September of 2007. It was used 32 adult ewes with 105 days of gest

10. Relação entre os padrões de secreção central e periférica de ocitocina: implicações sobre produção de leite em ovelhas / Relation between central and peripheral oxytocin realese: implications on milk production in sheep
The aim of the present work was to study a possible relationship between central and peripheral oxytocin release and its consequences to milk production during milking in experimental ewes. Ten multiparous Santa Ines ewes (Ovis aries) were divided in 4 groups according to milk ejection stimuli: exclusive machine milking (OME), mixedmanagement of milking and

11. Retorno ao estro pós-parto em ovelhas da raça Santa Inês e desempenho ponderal dos cordeiros: influência do manejo da alimentação e da amamentação
The return to the estrus and the postpartum weight of 60 Santa Inês ewe, as well as the lambs weight, from June to November of 2004 and 2005, were studied in Campo Maior (4 46 S and 4207 W), PI, Northeastern Region of Brazil. Blood samples were taken for the analysis of P4 and PRL in the sanguine plasma, at 15, 30, 45, 60, 75 and 90 days after the partum. T
