摘要
华润五丰北方肉牛育肥场参照NY/T 815—2004标准,采用4/6的精粗比设计育肥牛日粮,调整日粮养分密度以适应高纬度环境。考察发现,高寒地区肉牛养殖,可采用日粮季节日粮和异地肥育技术调控营养供给水平和肉牛环境适应能力,促进肉牛补偿生长。
According to NY/T 815—2004 standard, the Diet was designed with 4/6 concentrate-to-forage ratio, and the nutrient density was adjusted to adapt to the high latitude environment. It was found that beef cattle breeding in Alpine region could adjust the level of nutrition supply and the adaptability of beef cattle environment by using seasonal ration and off-site fattening techniques.
