摘要
文章旨在研究大蒜素对小尾寒羊生长性能、养分表观消化率及屠宰性能的影响。选取体况良好、日龄相近、初重37.26±1.85 kg的小尾寒羊120只,随机按3组×4重复×10只进行分组。3组分别饲喂基础日粮+0 g/t、200 g/t、400 g/t的大蒜素。预饲期7 d,正试期60 d。结果表明:(1)与0 g/t大蒜素组相比,200 g/t大蒜素组平均日增重和干物质采食量均显著提高11.93%(P<0.05)、7.58%(P<0.05);400 g/t大蒜素组平均日增重和干物质采食量均显著提高16.94%(P<0.05)、7.72%(P<0.05),且饲料转化率显著降低7.89%(P<0.05)。(2)与0 g/t大蒜素组相比,400 g/t大蒜素组干物质、粗蛋白质、中性洗涤纤维表观消化率显著提高(P<0.05)。(3)与0 g/t大蒜素组相比,200~400 g/t大蒜素组小尾寒羊的胴体重、屠宰率均显著提高(P<0.05)。结论:基础日粮添加400 g/t大蒜素能提高小尾寒羊生长性能,改善养分表观消化率及屠宰性能。
The experiment aims to investigate the effects of allicin on the growth performance,nutrient apparent digestibility,and slaughter performance of small tailed Han sheep.120 small tailed Han sheep with good physical condition,similar age,and initial weight of(37.26±1.85)kg were selected and randomly divided into 3 groups,with 4 replicates in each group and 10 sheep in each replicate.Three groups of small tailed Han sheep were fed with a basic diet of+0 g/t,200 g/t,and 400 g/t of allicin.The pre trial period is 7 days,and the main trial period is 60 days.The results showed that:(1)Compared with the 0 g/t allicin group,the 200 g/t allicin group significantly increased the average daily weight gain and dry matterby 11.93%(P<0.05)and 7.58%(P<0.05);The average daily weight gain and dry matter in the 400 g/t allicin group significantly increased by 16.94%(P<0.05)and 7.72%(P<0.05),and the feed conversion ratio significantly decreased by 7.89%(P<0.05).(2)Compared with the 0 g/t allicin group,the apparent digestibility of dry matter,crude protein,and neutral detergent fiber in the 400 g/t allicin group of small tailed Han sheep was significantly increased(P<0.05).(3)Compared with the 0 g/t allicin group,the body weight and slaughter rate of small tailed Han sheep in the 200-400 g/t allicin group were significantly increased(P<0.05).Conclusion:Adding 400 g/t of allicin to the basic diet can improve the growth performance,apparent nutrient digestibility,and slaughter performance of small tailed Han sheep.
