Prepartum fatty acid supplementation in sheep I. Eicosapentaenoic and docosahexaenoic acid supplementation do not modify ewe and lamb metabolic status and performance through weaning.

摘要: Fatty acids are involved in the regulation of many physiological pathways, including those gene expression and energy metabolism. Through effects on these fatty may have lifelong impacts offspring development metabolism via maternal supplementation. Therefore, our objective was to investigate impact supplementing a source omega-3 eicosapentaenoic acid (EPA) docosahexaenoic (DHA) during late gestation productive metabolic responses ewes their offspring. Eighty-four gestating (28 pens) were blocked randomly assigned diet with 0.39% added fat last 50 d (d -0). The sources Ca salts palmitic distillate (PFAD) or EPA + DHA. After lambing 1), all lambs placed same pasture. weighed BCS measured -50, -20, 30, 60 (weaning) experiment. Blood samples taken from 1 (lambing), 60. Milk yield composition at 30 postpartum. Lambs bled 1, 60, ADG calculated. All plasma analyzed for glucose NEFA. Ghrelin, prostaglandin E metabolites (PGEM), D2 metabolite 11β-PGF2α -20 ewe samples.
