摘要
试验旨在比较分析不同季节条件下对放牧牦牛生长性能及血清生化指标的影响。选取8头体况良好的健康牦牛为研究对象,分别于暖季和冷季在同一草场放牧。预试期10 d,正式试验期60 d。结果显示:暖季组牦牛的总增重及平均日增重极显著高于冷季组(P<0.01)。暖季组牦牛的血清白蛋白、谷丙转氨酶活性显著高于冷季组(P<0.05)。研究表明,暖季牦牛的生长状况明显比冷季好,对蛋白质的消化吸收利用情况更好,增重效果也更好。
The experiment was to compare the effect of different seasonal conditions on growth performance and serum biochemical indices of grazing yaks.Eight healthy yaks with good body condition were selected,which were grazed in the same pasture in warm season and cold season,respectively.The pre-test period lasted for 10 d,the formal test period lasted for 60 d.The results showed that the total weight gain and average daily gain of yaks in warm season group were extremely higher than those in cold season group(P<0.01).Serum albumin and ALT activity in warm season group were significantly higher than those in cold season group(P<0.05).The study indicates that the growth condition of yaks in warm season is obviously better than that in cold season,the digestion,absorption and utilization of protein were better,and the weight gain effect is better.
