五酸肽对哺乳母猪生产性能及其饲料养分消化率的影响 姚继明1 薛芹3 吕锋3 程勐万里3 程茂基2 1、广东旺大集团股份有限公司 2、安徽农业大学 3、安徽五粮泰生物工程股份有限公司 摘要：选取体况、胎次、体重和预产期相近的健康杜洛克哺乳母猪45头，随机分成3组，每组5个重复，1个重复3头母猪，即对照组、酸化剂组、五酸肽组，以探讨五酸肽对哺乳母猪生产性能及其饲料养分消化率的影响。结果发现：日粮中添加酸化剂3kg/吨和五酸肽10kg/吨后，哺乳母猪的采食量分别比对照组提高2.38%和21.60%（P0.05），仔猪日增重分别比对照组提高5.07%和14.08%（P0.05），仔猪死亡率分别比对照组降低9.65%和78.70%（P0.05）。哺乳母猪的采食量、仔猪日增重分别比市售酸化剂组提高18.77%、8.57%（P0.05），仔猪死亡率比市售酸化剂组降低76.43%（P0.05）。哺乳母猪的粗脂肪、粗蛋白、钙和磷的表观消化率分别比对照组提高4.02%、6.93%、10.04%和5.78%（P0.05或P0.01），分别比酸化剂组提高3.90%、4.96%、7.86%和4.16%（P0.05）。酸化剂与对照组的粗蛋白、粗脂肪、钙和磷的表观消化率差异不显著（P＞0.05）。结果表明：五酸肽能够明显提高哺乳母猪的繁殖性能和饲料养分消化率。 关键词：哺乳母猪；酸化酵解饲料；仔猪日增重；养分消化率 The Influences of Wusuantai on the Productivity and Digestibility of Feed Nutrition of Lactating Sows 【Abstract】In order to study the influences of Wusuantai on the productivity and digestibility of feed nutrition of lactating sows, 45 healthy lactating Duroc sows, which had similar body conditions, fetal times, body weight and expected date of confinement, were randomly divided into three groups, namely control group, acidifier group and wusuantai group, each group was divided into five subgroups and each subgroup included 3 lactating sows. The results show that when 3kg/ton acidifier and 10kg/ton Wusuantai were added to pig food, the feed intake of lactating sows of acidifier group and Wusuantai group were respectively 2.38% and 21.60% (P0.05) higher than that of control group, their daily gains of piglets were respectively 5.07% and 14.08% (P0.05) higher than that of control group and their death rates of piglets were respectively 9.65% and 78.70% (P0.05) lower than that of control group. Their feed intake of sows and daily gain of piglets were respectively 18.77% and 8.57% (P0.05) higher than that of commercially available acidifier group, and their death rates of piglets were 76.43% (P0.05) lower than that of commercially available acidifier group. Their apparent digestibility of crude fat, crude protein, calcium and phosphorus were respec
