摘要
试验主要研究在保育猪基础饲粮中添加葡萄糖氧化酶/水解单宁酸对保育猪生长性能、腹泻情况的影响。选取精神活泼健康的21日龄断奶仔猪3000头,随机分为对照组(饲喂基础饲粮)、试验组一(饲喂在基础饲粮中添加300 mg/kg葡萄糖氧化酶的试验饲粮)、试验组二(饲喂在基础饲粮中添加1000 mg/kg水解单宁酸的试验饲粮),每组设置25个重复,每个重复40头猪(母猪和阉割公猪各半)。葡萄糖氧化酶组和水解单宁酸组保育阶段腹泻率与对照组相比分别降低3.76、4.67个百分点(P<0.05);死淘率与对照组相比分别降低5.47、6.49个百分点(P<0.05);70日龄转群重与对照组相比分别增加2.79、7.46 kg(P<0.05);头均日采食量与对照组相比分别增加101、183 g(P<0.05);料重比3组差异不显著(P>0.05),葡萄糖氧化酶组料重比略有升高,水解单宁酸组略有下降。在饲粮中添加300 mg/kg的葡萄糖氧化酶或添加1000 mg/kg的水解单宁酸均可有效改善保育猪肠道健康状况,降低腹泻率和死淘率,提高转群重,具有一定的推广应用价值。
The experiment was conducted to study the effects of glucose oxidase/hydrolyzed tannic acid on growth performance and diarrhea of nursery pigs.Methods:three thousand 21 day old weaned piglets were randomly divided into control group(fed with basal diet)and experimental group 1(fed with basal diet supplemented with 300 mg/kg glucose oxidase)and experimental group 2(fed with basal diet supplemented with 1000 mg/kg hydrolysized tannic acid).There were 25 replicates in each group,40 pigs in each replicate(half sows and half castrated boars).Compared with the control group,the diarrhea rate in the glucose oxidase group and the hydrolyzed tannic acid group decreased by 3.76 and 4.67 percentage points respectively(P<0.05);the mortality rate decreased by 5.47 and 6.49 percentage points respectively(P<0.05);the group weight at 70 days of age increased by 2.79 kg and 7.46 kg compared with the control group(P<0.05);the first average daily feed intake increased by 101 g and 183 g respectively compared with the control group.There was no significant difference in feed/weight ratio(P>0.05).Adding 300 mg/kg glucose oxidase or 1000 mg/kg hydrolyzed tannic acid in the diet can effectively improve the intestinal health status of nursing pigs,reduce the diarrhea rate,reduce the mortality rate,and increase the weight of transferred pigs,which has certain application value.
