摘要:
本研究旨在验证放牧绵羊补饲复合预混料的应用效果，研究选取10月龄新疆细毛羊36只，按补饲情况将绵羊分为三个不同处理组，分为对照组、试验组1、试验组2，每日补饲量分别为0、500 g、500 g，补饲复合预混料为0%、0%、2%，分别于正饲期20天和40天进行称重，记录增重，于45天时进行采血，分离保留血清，测定血液指标，并选取绵羊进行屠宰，记录屠宰指标。实验结果表明，补饲复合预混料增重效果明显，试验组2比对照组增重13.41%，差异显著(P 0.05)；对照组与试验组2对比差异极显著(P 0.05)，对照组与试验组2相比较差异显著(P This study aimed to verify the effect of feeding premix application on grazing sheep so we selected 36 10-month-old Xinjiang fine-wool sheep. Through feeding situation the sheep were divided into three different treatment groups including the control group, the test group 1 and the test group 2. Daily feeding amount was 0 g, 500 g, 500 g and feeding premix was 0%, 0%, 2%. The sheep were weighed at regular feeding time, namely the 20th day and 40th day and weight gains were recorded. Blood samples were collected at the 45th day, serum was separated and retained and blood parameters were determined. And we selected the sheep to be slaughtered and recorded slaughter index. Experimental results showed that the effect of supplement premix on weight gain was obvious, the weight gain of test group 2 was 13.41% higher than of control group and this was sig-nificantly different (P 0.05). By a comparison of the content of hyperphosphatemia between test group 1 and control group the difference was not significant (P > 0.05). By a comparison of the content of hyperphosphatemia between test group 2 and control group the difference was significant (P 0.05). By a comparison of the content of IGg between test group 2 and control group, the difference was significant (P
