新疆褐牛犊牛放牧补饲试验效果分析

Analysis on Grazing and Supplementary Feeding Effect of Xinjiang Brow Calf

[目的]为了研究新疆褐牛犊牛放牧补饲增重效果。[方法]选择4~6月龄新疆褐牛80头作为研究对象,随机分为试验组和对照组,在不同饲养条件下进行日增重效果对比试验。[结果]表明：放牧加补饲的日增重效果明显优于纯放牧的饲养方式（P〈0.01）;新疆褐牛公犊和母犊的日增重效果差异不显著;放牧加补饲的新疆褐牛犊牛在第1个月和第2个月（8月、9月）的日增重明显高于第3个月（10月）,而纯放牧条件下则差异不显著。[结论]说明放牧加补饲育肥新疆褐牛犊牛具有较好的日增重效果,可在全疆推广。

【Objective】 The effect on grazing and supplementary feeding in Xinjiang brown calf was studied.【Method】80 individuals of 4~6 months old Xinjiang brown calf were selected and randomly divided into experimental and control groups.They were fed under different conditions to compare the effect on daily weight gain.【Result】 The results showed that the daily weight gain in grazing and supplementary feeding group was superior to that only grazing group（P0.01）.There was no significant difference between sire calf and dam calf in Xinjiang Brow cattle.Under the grazing and supplementary feeding condition of,the daily weight gain of the first（August） and second month（September） was superior to that of the third month（October）.But there was no significant difference among the three months under the condition of grazing.【Conclusion】The way of grazing and supplementary feeding had better daily weight gain in Xinjiang Brown calf.This feeding way could be promote in the whole Xinjiang pasture.
