摘要
用有机酸、无机酸及中草药配成复合酸化剂 ,添加于哺乳仔猪补料中。结果 ,试验组仔猪2 1,35,4 2日龄个体平均重均极显著高于对照组 ,消除了 35日龄早期断奶应激现象。试验组比对照组哺乳期腹泻率降低 34 2 0个百分点 ,断奶后一周死亡率降低 18 18个百分点。进一步研究表明 ,仔猪采食添加复合酸化剂的补料和日粮 ,消化器官的发育和营养物质的消化率高于对照组 ;小肠粘膜形态结构得到改善 ;胰腺。
Multi-acidizing agent consisted of organic acid, inorganic acid and Chinese herb medicine was added to the supplemental feed of sucking piglets. The results showed that the average body weight of piglets at 21d, 35d, and 42d was significantly higher than CK. Weanling stress of piglets at 35d was dispelled. The rate of diarrhoea for the treatment group was 34.20% lower than CK and mortality rate at a week after weanling decreased by 18.18%. Further research indicated that the development of digestive organ and digestive rate of nutrition were higher than CK by feeding with supplemental feed and diet added with multi-acidizing agent, and the mucosa morphology of small intestine was improved. At the same time, some important digestive enzyme activities such as in pancreas and duodenum were raised.
