【摘要】：杜仲叶是优质的粗饲料兼具药物活性物质,本试验旨在研究杜仲叶对绵羊营养物质消化利用、生长性能及屠宰性能的影响。选择30只体质健康、年龄和体重相近的绵羊(湖羊),随机分为3组,每组10只羊,分别为对照组(饲喂无杜仲叶的基础饲粮,CTL组)、低水平杜仲叶组(饲粮中含10%的杜仲叶,EUL1组)和高水平杜仲叶组(饲粮中含20%的杜仲叶,EUL2组),进行饲养试验和消化代谢试验。结果表明:饲粮中添加不同水平的杜仲叶对绵羊的末重、增重、采食量、日增重有显著影响(P0.05),对能量和氮的消化率、沉积率有显著影响(P0.05),对钙、磷的消化率和沉积率无显著影响(P0.05),对屠宰率和胴体净肉率有显著影响(P0.05),对胴体重、净肉重、骨重、骨肉比无显著影响(P0.05)。由此可见,杜仲叶对绵羊营养物质消化率、利用率及生长性能和屠宰性能等有明显的影响,影响程度与杜仲叶的用量有关。
[Abstract]:Eucommia ulmoides leaf is a kind of high quality crude feed with high drug activity. The purpose of this study was to study the effects of Eucommia ulmoides leaves on nutrient digestibility, growth performance and slaughtering performance of sheep. Thirty healthy sheep (Hu sheep) with similar age and weight were randomly divided into 3 groups with 10 sheep in each group. The control group (fed CTL without Eucommia ulmoides leaves), the low level Eucommia ulmoides leaves group (10% eucommia ulmoides leaf EUL1 diet) and the high level Eucommia ulmoides leaf group (20% eucommia ulmoides EuL2 diet) were fed for feeding and digestion and metabolism tests. The results showed that the addition of different levels of Eucommia ulmoides leaves in diet had significant effects on the end weight, weight gain, feed intake, daily gain of sheep (P0.05), on the digestibility of energy and nitrogen, deposition rate (P0.05), calcium and calcium. Phosphorus digestibility and deposition rate had no significant effect (P0.05), but had no significant effect on carcass weight, net meat weight and bone / meat ratio (P0.05). It can be seen that Eucommia ulmoides leaves have obvious influence on the digestibility, utilization ratio, growth performance and slaughter performance of sheep, and the influence degree is related to the amount of Eucommia ulmoides leaves.
