摘要

摘要: 在基础日粮中分别添加0.1%(试验Ⅰ组)和0.2%(试验Ⅱ组)的功能性卵黄粉,观察其对断奶仔猪生长性能、肠道菌群、肠绒毛形态的影响。结果表明:试验Ⅰ组和Ⅱ组仔猪的腹泻率分别极显著低于只喂基础日粮对照组的54.8%(P0.01)和84.3%(P0.01);试验第28 d,试验Ⅰ组粪便中致病性大肠杆菌数和细菌总数极显著低于对照组(P0.01);试验期间,试验Ⅱ组粪便中致病性大肠杆菌数和细菌总数均极显著低于对照组(P0.01);试验Ⅰ组、试验Ⅱ组仔猪的十二指肠的绒毛高度和V/C比值与对照组的差异极显著(P0.01)。试验Ⅰ组和Ⅱ组仔猪的日均增重分别显著高于对照组14.4%(P0.05)和15.3%(P0.05);日均采食量分别提高11.70%(P0.05)和6.86%(P0.05);料重比分别下降5.55%(P0.05)和6.50%(P0.05);结果表明功能性卵黄粉能有效地预防致病性大肠杆菌引起仔猪腹泻,能有效地提高仔猪生长性能。

Abstract: A 28 day-feeding experiment was conducted to determine the effects of the functional egg yolk powder as a feed ingredient on the growth performance,diarrhea occurrence,fecal microbe and the morphology of intestinal villi of the piglets.The results showed that(a) the diarrhea occurrence rates among the piglets in GroupⅠand Ⅱdecreased by 54.8%(P0.01) and 84.3%(P0.01),respectively,as compared to the control;and,(b) the fecal Escherichia coli at the 28th days decreased in GroupⅠ(P0.01),while decreased during the entire testing period in GroupⅡ(P0.01).The heights of the duodenum villi of piglets in GroupⅠand Ⅱwere greater than those in the control group(P0.01).The average daily piglet weight gain was significantly higher in both Group I and II than that of Control Group(P0.05),increased by 14.4% and 15.3%,respectively.The average daily feed intakes of the piglets in GroupⅠand Ⅱwere higher than that of the control(P0.05) by 11.70% and 6.86%,respectively.The feed conversion efficiencies for GroupⅠand Ⅱwere lower than that of the control(P0.05) by 5.55% and 6.50%,respectively.The results indicated that addition of the functional egg yolk powder in the feed could effectively inhibit the growth of the enterotoxigenic E.coli preventing piglets from diarrhea and improve their growth performances.
