黄花菜茎叶青贮与全株玉米青贮不同比例混合对滩羊生长性能及屠宰性能影响的研究

Effects of Different Proportions Mixed of Daylily Stem and Leaf Silage andWhole Corn Silage on Growth Performance and Slaughter Performance of Tan Sheep

为探究黄花菜茎叶青贮与全株玉米青贮不同比例混合对滩羊生长性能及屠宰性能的影响,试验将黄花菜茎叶青贮与全株玉米青贮按不同比例(0.10、1.9、2.8、3.7)混合,对滩羊开展饲喂效果及屠宰性能评估试验。结果表明:黄花菜茎叶青贮与全株玉米青贮不同比例混合对滩羊生产性能无显著差异(P>0.05),但黄花菜茎叶青贮与全株玉米青贮混合比例为2.8时增重效果具有提高的趋势。黄花菜茎叶青贮与全株玉米青贮混合时滩羊宰前活重、胴体重、净肉重、胴体净肉率显著(P<0.05)或极显著(P<0.01)提高。综上所述,黄花菜茎叶青贮与全株玉米青贮混合比例为2.8时,滩羊的生长性能及屠宰性能效果最优。

In order to explore the effects of different ratios of daylily stem and leaf silage and the whole-plant corn silage on the growth performance and slaughter performance of Tan sheep, the experiment carried out different ratios of dayily stem and leaf silage to whole-plant corn silage(0.10, 1.9, 2.8, 3.7) mix, the feeding effects and slaughter performance evaluation test of Tan sheep were carried out. The results showed that the different ratios of daylily stem and leaf silage and the whole plant corn silage had no significant difference on the production performance of Tan sheep(P>0.05), but the weight gain when the mixed ratio of daylily stem and leaf silage and the whole plant corn silage was 2.8, the effect had an improved tendency. When daylily stem and leaf silage was mixed with the whole-plant corn silage, the live weight, carcass weight, net meat weight and net meat rate of Tan sheep were significantly increased(P<0.05) or extremely significantly(P<0.01). In summary, when the mixing ratio of daylily stem and leaf silage to the whole-plant corn silage was 2.8, the growth performance and slaughter performance of Tan sheep were the best.
