Subsequent to a growth experiment with intensively fattened lambs the value of the carcasses of 4 animals each from 7 groups was determined. The control groups with mixed fattening feed for lambs and the groups with wheat and barley mixtures containing urea showed higher carcass yields, net gains, fat percentage and padding, dry matter and fat content of the carcass and lower quotas of important cuts as well as a lower crude protein content in the carcass than groups with grain without urea and groups with straw. This is due to the higher weight gains of the first-mentioned groups. There were no significant differences in the carcass characteristics between the animals of the control group and the grain-urea groups. The carcass quality of the male lambs was better than that of the female ones.
在对育肥羔羊进行生长实验后，测定了7组中每组4只动物的胴体价值。用羔羊混合育肥饲料的对照组以及用含尿素的小麦和大麦混合物的组，其胴体产量、净增重、脂肪百分比和膘厚、胴体干物质和脂肪含量均高于用不含尿素谷物的组和用秸秆的组，而重要切块的比例以及胴体粗蛋白含量则低于上述两组。这是由于上述前几组的体重增加较多。对照组动物与谷物 - 尿素组动物的胴体特征无显著差异。雄性羔羊的胴体质量优于雌性羔羊。
