Influence of colostrum from safflower supplemented ewes on lamb cold tolerance and lamb growth: Author: Robinson, Brenda Lee; Date: 2008-12-15; Program: Animal and Range Sciences; Abstract: Five hundred, ninety-seven and 643 white face range ewes were used in a 2 year study, respectively, in a 3-way factorial arrangement to determine effect of supplemental linoleic oil on lamb serum metabolites, thermogenesis and lamb growth. During the last 45 ± 4 days of gestation ewes were group fed a daily supplement of either 0.23 kg•ewe-1•d-1 whole safflower seed (SS) or 0.34 kg•ewe-1•d-1 whole barley (C). Colostrum was collected from each supplement treatment and pooled according to treatment. At parturition, twin born lambs...; Download File | View full details

Thermogenesis, serum metabolites and hormones, and growth in lambs born to ewes supplemented with docosahexaenoic acid: Author: Keithly, Jennifer Irene; Date: 2010-05-15; Program: Animal and Range Sciences; Abstract: Neonatal lamb mortality is a major factor effecting profitability in the sheep industry. Lamb thermogenesis and immunocompetence are key elements in neonatal lamb survival. Research has shown an increase in lamb vigor, when ewes were supplemented during late gestation with algae-derived docosahexaenoic acid (DHA). However, the impact of DHA on lamb thermogenesis and immunocompetence has not been investigated. Eighty twin-bearing Targhee ewes were assigned randomly to 1 of 2 supplemental treatments to determine the effects of feeding (DHA) to ewes during late gestation and early lactation on la...; Download File | View full details
