日粮中EM添加水平及方式对幼龄獭兔生长性能的影响

试验旨在研究EM添加水平及方式对幼龄獭兔生长性能的影响。将108只50日龄断奶仔獭兔随机分成9组(A-I),每组4个重复,每个重复3只兔子,并置于同笼内饲养。其中,A组为对照组,饲喂基础日粮;B组在基础日粮中添加抗生素;C组则向饮水中添加2‰EM;D、E、F组分别饲喂在基础饲料制粒前添加1‰、2‰、3‰EM的基础日粮;G、H、I组分别饲喂在基础饲料制粒后添加1‰、2‰、3‰EM的基础日粮。试验预饲期5 d,正饲期30 d,每天早晚各饲喂一次。结果表明:制粒前添加2‰EM组(E组)与A、B、C组比较,能极显著提高獭兔生长性能,制粒后添加1‰EM组与制粒前添加2‰EM组差异不显著。建议饲料中EM添加量为:制粒前添加2‰,或制粒后添加1‰。

Influence of the supplementation levels and ways of EM on growth performance in rex rabbits

The purpose of this study was to evaluate the effect of EM on growth performance in rex rabbits.108 fifty-day-old rabbits were randomly divided into nine treatments(A-I) with four replicates of three rabbits raised in the same cage.Group A was the control group fed with the basal diet.Group B was fed with the basal diet supplemented with antibiotic.Drinking water was supplemented with 2‰EM in group C.Group D,E,F,G,H,I were fed basal diet supplemented with 1‰,2‰,3‰ EM adding before and after granulation,respectively.Rabbits were fed twice one day in the morning and evening respectively.The previous trial period was 5 days and the formal trial was 30 days.The results showed that: the dietary EM supplemented with 2‰ EM adding before granulation and 1‰EM adding after granulation improved the growth performance significantly than the other groups.The suggested optimal supplement level of EM was 2‰ adding before granulation and 1‰ EM adding after granulation.
