【摘要】：[目的]通过对放牧新疆褐牛进行针对性的补饲,为放牧状态的新疆褐牛提高其生产性能提供科学依据。[方法]选取12~14月龄新疆褐牛30头,随机分为3组,试验组补饲基础日粮和在基础日粮中添加营养调控剂,第3组为放牧对照组。测定其试验前后体重,在试验最后1d,采集血液样本。[结果]在放牧条件下,补饲显著提高了放牧新疆褐牛在饲喂第60d时的体重、日增重,与放牧组相比,试验组显著增加末重和绝对日增重(P0.05),营养添加剂组极显著增加日增重(P0.01),营养添加剂组相对于放牧组多增重54.55%,基础日粮组显著增加日增重(P0.05),基础日粮组相对于放牧组多增重44.32%,营养添加剂组相对基础日粮组多增重7.09%。试验组总蛋白、白蛋白与放牧组差异显著(P0.05),试验组甘油三酯与基础料组差异显著(P0.05);试验组和基础料组钙均与放牧组差异显著(P0.05),试验组磷与基础料组和放牧组均差异显著(P0.05)。其他指标差异不显著(P0.05)。[结论]补饲增加新疆褐牛日增重;可以提高血清中蛋白的水平;补饲明显增加新疆褐牛的育肥效果,可以推广应用。
[Abstract]:[Objective] to provide scientific basis for improving the production performance of the brown cattle of Xinjiang brown cattle by grazing Xinjiang brown cattle. [Methods] 30 12~14 months old Xinjiang brown cattle were selected and divided into 3 groups randomly. The experimental group was supplemented with basal diet and supplemented with control agents in basic diet, and third groups were grazing control groups. The weight of the pre - and post test was 1D, and the blood samples were collected at the end of the test. [results] under the grazing condition, the feeding of Xinjiang brown cattle raised the weight, the daily weight increased, and the test group significantly increased the final weight and the absolute daily weight gain (P0.05) compared with the grazing group, and the nutrition additive group increased the daily weight gain (P0.01) and the nutrition additive group. Compared with the grazing group, the weight gain of the basal diet group increased significantly (P0.05), the basal diet group increased by 44.32% more than that of the grazing group, and the total protein of the 7.09%. test group in the diet group was more significant (P0.05) than that in the grazing group (P0.05), and the difference between the triglyceride and the base group was significant (P0.05). The difference of calcium between the experimental group and the base group was significant (P0.05). The difference of phosphorus in the experimental group and the base material group and the grazing group was significant (P0.05). The difference of other indexes was not significant (P0.05). [Conclusion] the supplemental feeding increased the daily weight of Xinjiang brown cattle; it could improve the level of protein in the serum, and the feeding effect of Xinjiang brown cattle could be significantly increased.
