五酸肽对生长保育猪生产性能及其饲料养分消化率的影响 张堂田1 孟秀丽2 吕锋3 程勐万里3 程茂基2 1、安徽宿州职业技术学院 2、安徽农业大学 2、安徽五粮泰生物工程股份有限公司 摘要：为研究五酸肽对生长保育猪生产性能及其饲料养分消化率的影响，选取18±0.5kg杜长大三元杂交健康生长保育猪300头，按体重、胎次相近，性别各半的原则随机分成5组，每组6个重复，每个重复10头猪。对照组不添加酸化剂，酸化剂组添加市售酸化剂3kg/吨，柠檬酸组添加柠檬酸5 kg/吨，乳酸组添加乳酸6 kg/吨，试验组添加五酸肽10 kg/吨。结果表明：日粮中添加酸化剂3kg/吨、乳酸6kg/吨、柠檬酸5kg/吨和五酸肽10kg/吨后，生长猪的日增重分别比对照组提高3.16%、4.32%、5.38%和13.08%（P0.05或P0.01），采食量分别比对照组提高1.73%、3.84%、3.43%和9.42%（P0.05或P0.01），料肉比分别比对照组降低1.39%、0.46%、1.85%和3.24%（P＞0.05）。干物质的表观消化率分别比对照组提高0.58%、1.71%、1.94%和6.12%（P0.05或P0.01），粗纤维的表观消化率分别比酸化剂组提高1.83%、2.52%、3.45%和6.91%（P0.05），粗蛋白的表观消化率分别比酸化剂组提高1.99%、2.13%、3.06%和6.42%（P0.05），钙的表观消化率分别比酸化剂组提高2.20%、3.19%、5.38%和10.59%（P0.05），磷的表观消化率分别比酸化剂组提高3.66%、4.10%、6.52%和8.94%（P0.05）。结果表明：五酸肽能够明显提高生长保育猪的生产性能，饲喂效果要好于市售酸化剂、柠檬酸和乳酸。 关键词：酸化酵解饲料；生长保育猪；生产性能；养分消化率 The Influences of Wusuantai on the Productivity and Digestibility of Feed Nutrition of Nursery Pigs 【Abstract】:In order to study the influences of Wutaisduan on the productivity and digestibility of feed nutrition of nursery pigs, 300 18±0.5kg healthy nursery duroc-landrace-yorkshire pigs were selected and randomly divided into five groups according to the principle of similar body weight and fetal times and fifty-fifty gender, each group was divided into 6 subgroups and each subgroup included 10 pigs. Control group was not fed with acidifier, acidifier group was fed with commercially available acidifier 3kg/ton, citric acid group was fed with citric acid 5kg/ton, lactic acid group was fed with lactic acid 6kg/ton and the experiment group was fed with Wusuantai 10kg/ton. The results show that when 3kg/ton acidifier, 6kg/ton lactic acid, 5kg/ton citric acid and 10 kg/ton Wusuantai were added to one ton of pig food, the daily gain of nursery pigs were respectively 3.16%, 4.32%, 5.38% and 13.08% (P0.05 or P0.01) higher than that of control group, the feed intake of nursery pigs were respectively 1.73%, 3.84%, 3.43% and 9.42% (P0.05 or P0.01) higher than that of control group and the feed
