Seventy-two pregnant ewes were al lot ted to three ration t reatment groups: 1) Control: corn silage and alfalfa pellets; 2) Tallow: corn silage, alfalfa pellets and protected tallow; 3) Polyunsaturated (P/S): corn silage and protected soybean and sunflower seeds. Diet influenced plasma glucose and linoleic acid content of esterified, but not of non-esterified, fat ty acids in ewe plasma. Propo...
Copper (Cu) plays an essential role in the human and animal body system. One of the most important sources of Cu is milk. The purpose of this study was to determine the effect of different doses of injection of inorganic Cu and organic Cu as Cu-arginine and Cu-lysine on Cu concentrations of milk in the lactating Zandi’s ewes. This experimental research involved 54 lactating Zandi’s ewes collect...
St. Croix White and Barbados Blackbelly hair sheep ewes were used to evaluate the effect of supplemental nutrition around lambing on ewe and lamb performance during the wet season on St. Croix. Beginning 14 d prior to expected day of lambing (day 0) and for 21 d postpartum, 11 ewes were fed a pelleted complete ration (17% crude protein) at a level to provide 150% of the nutrient requirements, i...
Since prion infectivity had never been reported in milk, dairy products originating from transmissible spongiform encephalopathy (TSE)-affected ruminant flocks currently enter unrestricted into the animal and human food chain. However, a recently published study brought the first evidence of the presence of prions in mammary secretions from scrapie-affected ewes. Here we report the detection of...
Soon after parturition a lasting and mutual ewe–lamb bond is established. However, in an increasing number of intensive sheep farms, lambs are separated from the dam at an early age. When artificial rearing is applied lambs are often kept with mothers for 2 days to allow the ingestion of maternal colostrum and then abruptly removed from their dams. Thus, lambs experience a marked emotional stre...
Ewe productivity is synonymous with annual litter-weight weaned (LWW) per ewe exposed to rams for breeding, and LWW is largely a function of number of lambs born (NLB) and weaned (NLW). Selecting for LWW should increase litter size and numbers of ewe-ram co-twins. Thus, we used historical records to determine whether sex of co-twin affected lifetime productivity of twinborn ewes. United States ...
Abstract The study was conducted in the animal barn of Agricultural Research Department/ Nineveh Department / Ministry Agriculture during period 1/3-15/4/ 2022, using 18 Awassi ewes last stage milk production (after weaning). ages ranged between 3-4 years and their average weight (46.80 ± 1.33 kg) were divided into three groups. first group considered control (T1) fed on standard ration without...
In this study 71 head of conceiving ewe and their progeny (91 head) from the flock of Lori-Bakhtiari sheep (360 head), in Sholi Station were randomly selected to determine the relationship between the immunoglobulin (IgG) concentration in the ewe's serum and colostrum, and lamb's serum. Ewe blood sample, colostrum of ewe and blood of the lamb was taken 2 weeks before parturition, 1 to 8 hours a...
