加丽素红对海兰蛋鸡生长及产蛋性能的影响

Effect of carophyll red on growth and egg production performance of Hy-line chicken

试验探讨加丽素红对海兰蛋鸡生长及产蛋性能的影响,为加丽素红在畜牧养殖业中的合理使用提供依据。试验采用随机分组的方法,设立一个对照组、两个剂量组(分别添加80和8 000 mg/kg加丽素红)。每组海兰蛋鸡36只,分别饲喂基础饲料和添加不同剂量加丽素红的饲料。结果表明,通过对鸡的体重、平均日增重、平均日采食量、料重比等生长性能指标的统计分析,加丽素红对上述指标无显著影响;通过对开产蛋重、产蛋率、平均蛋重等产蛋性能的统计分析,加丽素红对上述指标无显著影响;但加丽素红可以使蛋鸡的开产日龄提前。

The aim of this study is to investigate the effects of carophyll red on growth and egg production performance of hy-line chicken.It would provide scientific evidences for the reasonably using of carophyll red in animal husbandry.The present study was divided into three groups at random.36 Hy-line chickens were selected as control group,fed basic feeds alone,while two treatment groups（36 Hy-line chickens per group）were fed basic feeds with 80 mg/kg and 8 000 mg/kg of carophyll red as low and high dose treatment groups respectively.There were no significant differences（P0.05） between two treatments groups and control group in growth performance,including body weight,average daily gain,average daily intake and feed gain ratio.Moreover,there were no significant differences（P0.05） between two treatments groups and control group in egg production performance,including weight of first egg,egg production ratio,average egg weight.However the age at first egg of the chicken was advanced by adding carophyll red.
