饲料中添加地黄多糖对母猪繁殖性能和育肥猪生长性能的影响
Effects of Rehmannia Polysaccharides on the Reproductive Performance of Sows and the Growth Performance of Fattening Pigs
摘要
Abstract
This study aimed to investigate the effects of adding Rehmannia polysaccharides to feed on the reproductive performance of sows and the growth performance of fattening pigs.(1)A total of 2 400"Landrace × Yorkshire"crossbred sows with similar body weight and good health were selected as the experimental group,and 2 360 crossbred sows were selected as the control group.(2)A total of 139"Duroc × Landrace × Yorkshire"crossbred fattening pigs were selected as the experimental group,and 138 crossbred fattening pigs with the same age and similar body weight were selected as the control group from a fattening pig farm.The control group was fed a basal diet,while the experimental group was fed the basal diet supplemented with 100 mg/kg of Rehmannia polysaccharides.The trial period lasted for 5 months.The results showed that,compared with the control group,the addition of Rehmannia polysaccharides to the feed significantly increased the 7-day farrowing rate and conception rate of sows,reduced the rate of non-viable piglets and the mor-tality rate of piglets during the lactation period,increased the weaning weight of piglets,and increased the number of piglets weaned per litter(P＜0.05).In fattening pigs,the addition of Rehmannia polysaccharides to the feed significantly increased the daily weight gain and reduced the feed-to-gain ratio(P＜0.05).The addition of Rehmannia polysaccharides to the feed could significantly improve the reproductive performance of sows and the growth performance of fattening pigs,reduce production costs,and increase the efficiency of pig production,with a view to reducing farm production costs and increasing productivity.关键词
