摘 要:试验通过在断乳仔猪饲料中加入不同浓度植物精油,研究不同浓度植物精油对断乳仔猪生长性能和免疫反应的影响。从猪群中挑选120头体重接近的健康断乳仔猪作为试验动物,采用随机分组的方法,将断乳仔猪随机分成4组,每组3个重复,每个重复10头断乳仔猪。Ⅰ组:空白组,饲喂基础日粮;Ⅱ组:在基础日粮中加入200 mg/kg植物精油;Ⅲ组:在基础日粮中加入400 mg/kg植物精油;Ⅳ组:在基础日粮中加入600 mg/kg植物精油。试验期21 d。结果表明:在生长方面,4个组的平均初重、平均日采食量和料重比进行比较时,无显著差异(P>0.05);与Ⅰ组相比,Ⅱ组、Ⅲ组、Ⅳ组的平均末重均超过Ⅰ组,但并未达到显著差异水平(P>0.05);Ⅱ组、Ⅲ组和Ⅳ组的平均日增重均显著高于I组(P<0.05),平均日增重分别提高了4.56%、5.67%、4.43%。在腹泻率方面,Ⅱ组、Ⅲ组和Ⅳ组的腹泻率均显著低于I组(P<0.05),分别降低了28.78%、28.36%、27.94%;Ⅱ组、Ⅲ组和Ⅳ组之间腹泻率差异不显著(P>0.05)。在免疫方面,4个组的血清IgA、IgM含量差异均不显著(P>0.05);Ⅱ组、Ⅲ组的IgG含量均显著高于I组(P<0.05),分别提高了16.17%、14.89%。由此可见,饲喂植物精油能够改善断乳仔猪的生长性能、有效降低断乳仔猪腹泻率,增强断乳仔猪机体体液免疫。The experiment investigates the effects of different concentrations of plant essential oils added to the feed of weaned piglets on the growth performance and immune response.A total of 120 healthy weaned piglets of similar weight were selected from the herd as test animals,using a random grouping method,the experimental animals were randomly divided into four treatment groups with 3 replicates in each group,and each replicate was 10 piglets.Ⅰgroup was blank control group,fed with a basic diet;II group was fed with a basic diet supplemented with 200 mg/kg of plant essential oils;III group was fed with a basic diet supplemented with 400 mg/kg of plant essential oils;IV group was fed with a basic diet supplemented with 600 mg/kg of plant essential oils.The experimental period was 21 days.The results showed that in terms of growth performance,when the average initial weight,average daily feed intake and feed to gain ratio of the four groups were compared,these differences were not significant(P>0.05).Compared withⅠgroup,the average final weight ofⅡgroup,Ⅲgroup andⅣgroup were higher than those of I group,but the differences were not significant(P>0.05),the average daily gain of II group,III group,and IV group were significantly higher than those of I group(P<0.05),and the average daily gain increased by 4.56%,5.67%,and 4.43%,respectively.In terms of diarrhea rate,the diarrhea rates of II group,III group,and IV group were all significantly lower than those of I group(P<0.05)by 28.78%,28.36%,and 27.94%,respectively;there were no significant differences in diarrhea rates among II group,III group,and IV group(P>0.05).In terms of immunity,there were no significant differences in the serum IgA and IgM levels among the weaned piglets of all groups(P>0.05);the IgG levels in II group and III group were significantly higher than those in I group(P<0.05)by 16.17%and 14.89%,respectively.It can be seen that feeding with plant essential oils can improve the growth performance of weaned piglets,effectively reduce the diarr
