Abstract
This experiment was conducted to study the effects of adding β-hydroxy-β-methylbutyrate (HMB) to sow diets in late pregnancy and lactation period on sows reproductive performance and piglets performance and their immune function.A total of 24 pregnancy sows (Landrace × Yorkshire) with similar farrowing date and 3 ～ 6 births were selected and randomly divided into 2 groups according to parity,weight and body condition,resulting in 12 repetitions in each group.Control group was fed a basal diet and experimental group was fed the basal diet supplemented with 0.2％ HMB.The experiment was from day 84 of gestation to day 21 after parturition.The results showed that compared with the control group,the litter and average weight at birth of experimental group piglets were increased by 10.70％ and 3.95％,those at 7 days of age were increased by 6.12％ and 5.58％,those at 21 days of age were increased by 6.70％ and 5.45％,litter body weight gain and average daily gain from birth to 21 days of weaning age were increased by 8.08％ and 7.55％ (P＞0.05).The serum IgG of sows in experimental group was significant ly higher than the control group (P＜0.01).It is concluded that adding 0.2％ HMB to sow's diets from pregnant 84 days to lactation has the tendency to enhance body weight at birth and body weight gain during suckling periods of piglets,and to improve immune function of sows.关键词
