摘要
将益生素和柠檬酸添加到28日龄艾维茵肉鸡的基础饲料中。益生素的添加量分别为0.0%、0.1%、0.5%三个水平;柠檬酸的添加量分别为0.0%、0.1%、0.5%三个水平。采用L9(34)正交表设计,通过28d的试验,结果表明,益生素、柠檬酸单独添加,对艾维茵肉鸡的料重比有非常显著的降低作用(P<0.01),大幅度提高了艾维茵肉鸡的生长性能。同时添加时,二者还有显著的交互作用(P<0.05),试验最优处理为益生素0.5%、柠檬酸0.5%。
Supplement the probiotic and citrate with the basal ration of the 28-day age Avine, broiler, both of them had 0.0%、0.1%、0.5%three levels. Adopted the orthogonal experimental method, passed on a 28 days on trial, and the result showed that: the probiotic, the citrate, While alone using, each of them can extrement significantly decreased the feed-weight ratio(P<0.01),the supplement of the probiotic and citrate was 0.5% and 0.5%, obviously improved Avine's groth coefficient; Whilc be in conjunction of the usage, there is a significant synergism between them(P<0.05),the best treatment is:the probiotic was 0.5% and the citrate was 0.1%.
