摘要
畜牧业生产中,饲料成本占总成本的70%以上,粮食饲料占常规畜禽饲料的80%以上,在提供畜产品的过程中占有相当重要的地位。但随着人们生活水平的不断提高,人们对畜产品的需求日益增大,粮食饲料作为常规饲料的供需缺口越来越大,过度地依赖粮食来用作饲料已不能满足畜牧业发展的需要,因此必须利用我国丰富的非常规饲料资源来满足需求。开发非常规饲料是缓解饲料资源不足、降低畜禽饲养成本、提高经济效益的一条重要途径。
In the production of animal husbandry, the feed cost accounts for more than 70% of the total cost, and the grain feed accounts for more than 80% of the conventional livestock and poultry feed, which plays a very important role in the process of providing livestock products. However, with the continuous improvement of people’s living standards, people’s demands for animal products are increasing day by day. The gap between the supply and demand of grain feed as a conventional feed is getting larger and larger. Excessive reliance on grain as feed can no longer meets the needs of animal husbandry development. Developing unconventional feed is an important way to alleviate the shortage of feed resources, reduce the cost of raising livestock and poultry, and improve the economic benefits.
