Energy metabolism and lactation performance of primiparous sows as affected by dietary fat and vitamin E

摘要: In this thesis different levels of dietary fat (37, 43, 75 and 125 g/kg DM, respectively) vitamin E (from 14 to 151 mg α-tocopherol/kg diet) in the lactation diet, were studied for their effect on energy metabolism, performance primiparous sows. The effects (13, 48 136 types (50 sunflower oil or animal fat) gestation diets, some immunological parameters sows piglets also investigated. It was found that a high level diet decreased daily heat production As consequence energetic efficiency milk improved. A increased output. quantity from not influenced by fat, nor diet. pregnancy diets had no consistent measured cell-mediated humoral immunity lactating results present studies indicate sows' can improve variables piglets. sources tested
