艾维茵肉鸡饲料配方对比试验

Comparative Test of Feed Formula of Avian Broiler

重庆梁平饲料科学研究所用 40 0羽艾维茵出壳鸡做饲养试验 ,将其新近研究生产的改进型饲料与其目前在市面上出售的两种饲料 (分别称配方甲和配方乙 ,作为对照 )及改进型饲料 3个处理间的前期料和中期料分别进行比较。结果表明 ,改进型饲料 3个处理共 6个重复中 ,有 3个重复增重速度比配方甲分别高出 5 .1%、5 .7%和 6.8% ,经统计分析差异显著 (P <0 .0 5 ) ,其余 3个重复增重也超过配方甲。 6个重复中有 4个重复超过配方乙 ,但差异不显著 (P >0 .0 5 )。在饲料转化率方面 ,前期料 ( 1～ 3周 )仅 2个重复高于配方甲 ,全部高于配方乙。中期料明显优于配方甲和配方乙。

Avian broilers were used to conduct the feeding trial by Liangping feeds research institute of Chongging.The feeding trial was the comparative tests among a new improved diet group and the groups of to original diets sold in market(feed formula A and B,resp.)and among three treatment groups of the improved diet in earlier stage and in mid stage.The results showed that the liveweight gain in three repeat groups among six repeat groups of three treatment of the improved diet was 5.1%,5.7% and 6.8% more than that in the feed formula A group resp.(P<0.05).The liveweight gain of other three repeat groups also was more than that in the feed formula A group(P>0.05).The liveweight gain in four repeat groups was more than that in the feed formula B group(P>0.05).The feed efficiency in six repeat groups of the improved diet of earlier stage (1～3 weeks) was more than that in the feed formula B group and one in two repeat groups was more than that in the feed formula A group.The feed efficiency in all the repeat groups of the improved diet of mid stage(4～6 weeks)was significantly more than that in the feed formula A and B groups.
