酵母培养物对安徽白山羊和波尔山羊生长发育的影响

Effects of Yeast Culture on the Growth and Development of Anhui White Goat and Boer Goat

以安徽白山羊和波尔山羊为试验动物,探讨酵母培养物对其生长发育的影响。结果表明,体重方面,在A组、B组和C组内,试验组比对照组的总增重分别多33.79%、11.76%和18.00%,且A组中试验组总增重和平均日增重极显著高于对照组(P<0.01);体尺方面,A组中试验组体斜长增长显著高于对照组(P<0.05),C组中试验组尻宽增长显著高于对照组(P<0.05),A组中试验组体高增长极显著高于对照组(P<0.01);经济效益方面,A组、B组和C组内的试验组比对照组平均每只羊分别多获利15.87、4.14和8.05元。

Anhui White Goat and Boer Goat were choosed in this study. Effects of yeast culture on the growth and development of them were discussed. The results showed that, in terms of body weight, the total weight gains in the experimental groups in- creased by 33.79%, 11.76% and 18.00% respectively than the control groups in group A, group B and group C. And in group A, there were significant differences （P〈0.01） between the experiment group and the control in total weight gain and average daily gain. For tile hody size, significant difference （P〈0.05） was observed between the experiment group and the control in group A about the growth of body length, and the same difference （P〈0.05） was found between the experiment group and the control in group C about the growth of rump width. Furthermore, the growth of body height got significant difference （P〈O.O1） between the experiment group and the control in group A. In A, B and C groups, the average profit of each goat in the experiment groups were higher than those in the control groups by 5.87, 4.14 and 8.05 yuan respectively.
