不同饲料对甘南牦牛暖季补饲育肥效果研究试验

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]本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+放牧补饲育肥组试验末总增重分别比苜蓿颗粒+放牧和纯放牧的方式分别提高了32.46%,20.97%,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。

Effects of different feeds on supplementary feeding and fattening of yak in warm season

The traditional yak grazing production model in Gannan has caused problems in yak prodduction such as long cycles, low returns, and high pressure on pastures. The urgent needs of "national", "local" and "herders" for grassland ecological protection, economic development and increased income have made high production efficiency an urgent need for the development of yak. Objective]In order to improve the fattening effect of yak in warm season, methods] This study uses different feed formulas to feed and fatten the yak in warm season. results] The test results show that the total weight gain of the steam compressed corn + grazing group is higher than that of alfalfa pellets. The grazing and pure grazing methods have increased by 32.46% and 20.97% respectively, and the economic benefits have increased by 23.21% and13.55% respectively compared with the above two groups. conclusions] Therefore, the steam-pressed corn + grazing warm-season fattening method group is suitable for yak production in the vast pastoral area Promotion and application.
