摘　　要：甘南牦牛传统放牧生产模式使牦牛生产存在周期长、收益低、草场压力大等问题,而国家、地方和牧民对草地生态保护、经济发展、增加收入的迫切需求,使得高生产效率已成为牦牛发展的迫切需要。[目的]为提高牦牛暖季育肥效果,[方法]试验利用不同饲料对牦牛进行暖季补饲育肥,筛选适合甘南牧区最佳育肥方式,为牦牛高质量发展提供技术支持和理论指导。[结果]试验结果表明,采用蒸汽压片玉米+放牧组试验末总增重分别比苜蓿颗粒+放牧和纯放牧的方式提高了20.97%,32.46%,经济效益分别比以上两组提高了23.21%,13.55%。[结论]因此,蒸汽压片玉米+放牧暖季补饲育肥方式组适合在广大牧区甘南牦牛生产中推广适用。The traditional yak grazing production model in Gannan has caused issues in yak production such as long cycles, low yields, and high pressure on pastures. The urgent needs of national, local and herders for ecological protection of grasslands, economic development and increased income have made high production efficiency an urgent need for the development of yak. [Objective] Improve the fattening effect of yak in the warm season. [Method] This study used different feed formulas to feed and fatten yaks during warm season. [Result] The study results show that total weight gain in steam compressed corn + grazing group is higher than in alfalfa pellet groups. The grazing and pure grazing methods have increased by 20.97% and 32.46% and economic benefits have increased by 23.21% and13.55%, respectively, compared to the above two groups. [Conclusion] Therefore, the steam-pressed corn + grazing warm-season fattening method group is suitable for promotion and application in yak production in vast pasture areas.
