饲料制粒对吉戎兔生长性能的影响

Effect of feed pelleting on the growth performance of Jirong rabbits

试验对颗粒饲料和粉状饲料饲喂吉戎兔效果生长性能的影响进行了初步探讨。试验选取胎次相同,初始体重无显著差异（P〉0.05）,60~66日龄健康吉戎幼兔100只,公母各半,随机分为2组,试验组饲喂颗粒饲料,对照组饲喂粉状饲料。试验期为30 d。试验结束测定2组平均日增重、平均日采食量以及料重比;测定日粮中的粗蛋白、粗脂肪、粗纤维表观消化率。结果表明：颗粒饲料组与粉状饲料组日增重差异显著（P〈0.05）,颗粒饲料组比粉状饲料组提高了9.57%;颗粒饲料组与粉状饲料组料重比差异显著（P〈0.05）,颗粒饲料组比粉状饲料组降低了13.13%;颗粒饲料组与粉状饲料组的粗蛋白、粗脂肪消化率差异显著（P〈0.05）,分别提高了9.01%、5.00%,粗纤维消化率的差异极显著（P〈0.01）,提高了31.87%。

It preliminary discussed about effect of pellet feed and powder feed on the growth performance of Jirong rabbit in the test.The 100 young Jirong rabbit who were healthy,60~66 day-old,had no significant difference in body weight（P0.05）,with same male and female were randomly divided into two groups.The experimental group was fed with pellet feed and the control group was fed with powder feed.The experimental period was 30 days.The average daily gain,average daily feed intake,feed gain ratio were measured between two groups at the end of the test.And the dietary crude protein,crude fat,crude fiber digestibility were measured.The results showed that： ADG（average daily gain） of the pellet feed group increased by 9.57% compared with the powder feed group（P0.05）.The feed gain ratio of the pellet feed group reduced by 13.13% compared with the powder feed group（P0.05）.Compared with the powder feed group,digestibility of crude protein and crude fat of the pellet feed group significantly increased by 9.01%,5.00% respectively（P0.05）,crude fiber digestibility was significantly increased by 31.87%（P0.01）.
