Malpura and Kheri ewes (76) in their late gestation, weighing 34.40±0.95 kg were randomly selected and divided into 4 groups of 19 each (G1, G2, G3 and G4). Ewes in all the groups were grazed on natural rangeland from 07.00 h to 18.00 h. Ewes in G1were maintained on sole grazing while ewes in G2, G3 and G4, in addition to grazing received concentrate mixture at the rate of 1% of their body weig...

The objective of this study is to prospectively evaluate the seroepidemiology maedi-visna (MV) infections in intensively reared dairy sheep. A total 407 purebred Chios and Lacaune ewes from four farms were surveyed for two consecutive years serologically tested semiannually with an indirect ELISA at pre-mating pre-lambing. farms’ structure management practices similar animal traits (age, breed,...

FOR FULL BIO CLICK HERE Welcome to the seventh issue of Sheep and Beef Research Review. The content in this issue is split evenly between the ovines and bovines. Ovine highlights include clinical and sub-clinical mastitis and the nutritional management of lactating ewes while bovine highlights include sustained internal parasite control in beef heifers and the importance of colostrum for neonat...

This study was conducted to determine whether exposure of ram lambs to estrual ewes during their first autumn and again as adults just before serving capacity tests (SCT) affected the outcome of the sexual performance tests. Treatments were either early exposure of Polypay ram lambs (i.e., 7-8-mo-old rams with ewes for 17 d [n=30] or no early exposure [n=30]), and late exposure (i.e., 16-19-mo-...

Two studies were performed to evaluate early pregnancy diagnosis by transrectal ultrasonography (TRUS), using a 7.5-MHz ransducer in ewes. In the first study, the objectives were to determine the earliest date that a reliable pregnancy diagnosis could be ade (percentage of ewes detected pregnant between days 15 and 20 after mating). In the second study, the objective was to confirm he findings ...

Melatonin in Silastic capsules was implanted subcutaneously to examine the effect on reproductive activities of anestrous ewes under natural photoperiods. The constant supply of melatonin from the capsules increased plasma melatonin levels in a dose dependent manner, and high concentrations exceeding the endogenous night peaks were maintained throughout the day in the ewes carrying two capsules...

The albumin/globulin (A/G) ratio can be an immunological indicator of sheep which influenced by reproductive status such as pregnant and lactation conditions. However, a study A/G during in thin-tailed is still lack. This aimed to determine the levels pregnancy lactation. used twelve ewes sheeps (seven sheeps, five lactating sheeps) rearing Berbah, Sleman, Yogyakarta. Blood samples were collect...

Abstract The aim of this study was to evaluate the effects diets with fatty acid profiles on lactation performance and milk composition ewes. Dorper vs. Santa Inês ewes (n=40; 54.9 ± 8.3 kg BW 14 days in milk) were penned individually used a randomized complete block design. Ewes fed basal diet (19.87 0.62% CP) containing 70% concentrate 30% coastcross hay, no added oil (CON). remaining 4.0% so...

In a recent study, we observed that starch-rich diets used in mid lactation induced lower milk production persistency and higher body fat accumulation dairy ewes compared with goats. Because these species differences could be linked to hormonal mechanisms drive energy partitioning, the same experiment, explored evolution of metabolic status during test this hypothesis. Twenty mature Sarda 20 Sa...
