摘要
为了研究两种禾本科牧草(玉淇淋58号和桂牧1号杂交象草,分别简称YQL58和GM1)饲喂川南黑山羊效果,试验对两种牧草的适口性、川南黑山羊的生产性能和经济效益进行了比较分析。结果表明:(1)自由采食情况下川南黑山羊会优先采食YQL58。(2)在预饲期结束体重、试验期结束体重方面,2个组差异不显著(P>0.05);在试验期增重和试验期日增重方面,2个组差异不显著(P>0.05),但YQL58组有大于GM1组的趋势;在料肉比方面,YQL58组小于GM1组;在精饲料采食量和青饲料采食量方面,两个组基本无差异。(3)YQL58组和GM1组川南黑山羊在试验期经济效益分别为173.5元/只和155.5元/只。综上,YQL58比GM1饲喂川南黑山羊有更好的适口性、更优的生长性能和更大的经济效益。
In order to study the effects of two kinds of gramineae forage grass( YQL58 and GM1) to feed the south sichuan black goat,the test of the palatability of YQL58 and GM1,the production performance and the profit of the south sichuan black goat of a comparative analysis. The results showed that:(1)the south sichuan black goat give priority to eat YQL58 in the case of free feed.(2)the weight of the end of pre-feeding and the weight of the end of the trial had no significant difference between YQL58 group and GM1 group( P > 0. 05); the weight gain of the trial and the average daily weight gain had no significant difference between YQL58 group and GM1 group( P > 0. 05),but the weight gain of the trial and the average daily weight gain of YQL58 group had higher than that of GM1 group; the meat ratio of YQL58 group had smaller than GM1 group. there was no difference between the two groups in terms of feed intake and green feed intake.(3)the profit of YQL58 group and GM1 group were 173. 5 yuan per and 155. 5 yuan per. The results showed that the palatability and the growth performance and the profit of using YQL58 to feed the south sichuan black goat had better than that of GM1.
