包被植物精油对AA肉鸡生产性能的影响

The Effect of Plant Essential Oils on the Production Performance of AA+Broiler Chickens

该试验旨在探讨日粮中添加不同剂量的包被植物精油对肉鸡生产性能的影响。选取1350只健康0日龄AA肉鸡,随机分为3组,每组3个重复,每个重复150只。其中试验1组(基础日粮+50 g/t包被植物精油)、试验2组(基础日粮+100 g/t包被植物精油)、试验3组为对照组(饲喂基础日粮),试验期为56 d。在试验过程中,鸡发生腺胃炎和新城疫情况下,结果显示,与对照组相比,试验1组和试验2组在各阶段均显著提高了AA肉鸡的平均日增重及平均日采食量;整个试验周期中,试验1组和试验2组与对照组相比平均日增重分别提高了26.30%、35%(P<0.05);试验2组与对照组相比平均日采食量显著提高了8.14%;饲喂包被植物精油可以显著提高肉鸡的成活率3.91%(P<0.05),同时能够显著提高肉鸡出栏重968 g/只(P<0.05),而且试验2组平均每只鸡盈利0.42元;对照组平均每只鸡亏损7.3元,在饲料里添加植物精油,经济效益明显。

This experiment was conducted to investigate the effects of different doses of coated plant essential oil on the production performance of broilers.A total of 1350 healthy 0-day-old AA broilers were randomly divided into 3 groups with 3 replicates per group and 150 broilers per replicate.The test group 1(basal diet+50 g/t coated plant essential oil),the test group 2(basal diet+100 g/t coated plant essential oil),and the test group 3 were the control group(fed basal diet).The test period was 56 days.During the trial,broilers developed proventriculitis and Newcastle disease.The results showed that compared with the control group,the average daily gain and average daily feed intake of AA broilers in the experimental group 1 and the experimental group 2 were significantly increased at each stage.During the whole test period,the average daily gain of test group 1 and test group 2 increased by 26.30%and 35%respectively compared with the control group(P<0.05).The average daily feed intake of the experimental group 2 was significantly increased by 8.14%compared with the control group.The coated plant essential oil could significantly increase the survival rate of broilers by 3.91%(P<0.05),and could significantly increase the slaughter weight of broilers by 968 g(P<0.05),The average profit of each broilers in the experimental 2 groups was 0.42 yuan.In the control group,the average loss of each chicken was 7.3 yuan.To use the plant essential oil in the feed,the economic benefit is obvious.
