摘要
四川省是牦牛、犏牛生产大省,存栏量常年保持在高位,给草地生态环境造成巨大压力。但牦牛、犏牛养殖量的提升并未给牧民带来经济收入的增加,这与藏区冬春季恶劣的自然环境导致的营养缺乏密切相关。为解决这个问题,本试验将2.5~3.5岁的牦牛、犏牛运往四川省的农区(广汉)开展冬春季育肥研究,分析其带来的经济效益。通过120d的短期育肥,牦牛、犏牛分别增重64.00kg和85.80kg,增收645元/头和1 299元/头。试验结果表明,牦牛、犏牛可以通过在农区进行冬春季育肥达到增收的目的。
Sichuan is a large yak(Bos grunniens) production province,and the high stocks number causing a tremendous pressure on the grassland ecological environment.The increase number in yak farm has not brought economic income of famer,which is mainly caused by the lack of nutrition in the harsh natural environment in winter and spring.In order to solve the problems,we transported yak and yak-cattle(2.5 to 3.5 years old) to the agricultural area of Sichuan Province(Guanghan),and made a short-term fattening benefit analysis of yak and cattleyak in winter and spring.Through the 120-day short-term fattening study,the yak and cattle-yak weight increased64.00 kg and 85.80 kg on average,and the benefit increased 645 yuan and 1299 yuan,respectively.The test results show that yak and cattle-yak can be used for fattening in winter and spring in the agricultural area.At the same time,achieve the purpose of increasing income.
