摘要
选择90只无角道塞特(♂)与小尾寒羊(♀)的杂交一代羔羊(30日龄)随机分为3组,每组10只羔羊,公母各半。采用单因子设计,研究19%,17%,15%蛋白水平日粮补饲羔羊的效果。试验结果表明:三组羔羊日增重分别为291g/d、319g/d、258g/d,第2组、第3组间日增重差异显著(P<0.05),第2组日采食量显著高于第3组(P<0.05),第1组料肉比优于第3组(P<0.05)。19%和17%蛋白水平日粮适于羔羊补饲,其中以17%水平最好。
<Abstrcat> Ninety crossed lambs (1 month) of Dorset(♂)×Small Tail Han sheep (♀)were divided into three treatments. Single factor design was used in the study with different nutritional level. The results showed that daily weight gain were 291?319?258 g in order of treatment, and efficiency of gain of the second treatment was significant higher(P<0.05)than that of the third treatment. It was also proved that daily intake of third treatment was very significantly lower than that of second treatment(P<0.05), and efficiency of feed utilization of the third treatment lambs was very significantly lower than that of first treatment (P<0.05). In a word, the lamb will get much better performance with 17% protein nutritional level diet.
