中文摘要:

      [方法]对已经度过适应期的3～4岁青年公母牛30头（雌雄各15头）进行饲喂观察，每月称重2次，并对每月经济投入与牦牛的产出做相关分析。[结果]结果显示，1—5月份和9—11月份2个时段育肥效果很理想，日增重超过了0.4 kg/d，其中3月份的效果最理想，可达到0.5 kg/d；7—8月份时间段育肥效果很不理想，日增重几乎为0，7—8月份时间段内在沙漠地域中所建的牛场不适合育肥牦牛；虽然不同月份牦牛所产生的经济效益不同，但所有的月份对牦牛的身体并无明显的损坏作用。

英文摘要:

      [Method] 30 breeding yaks (15 male and 15 female) aged 3 to 4 years old who had already passed the adaptation period were fed and observed. The correlation between monthly economic input and yak output was analyzed by weighing twice a month. [Result] The experimental results showed that the fattening effect was very ideal in the two periods from January to May and September to November. The daily weight gain was more than 0.4 kg/d, among which the effect in March was the most ideal, reaching 0.5 kg/d. The effect of fattening in July and August is not ideal, the daily weight gain is almost 0, the yak farm built in the desert during July and August is not suitable for fattening yaks. Although different months have different economic benefits, all the months have no obvious damage to the yak's body.
