随着饲养业专业化、商品化的深入发展,对饲料的数量和质量的要求将日益增长和提高,依靠国家提供的饲料粮来生产配合饲料已远不能满足需要,而蛋白质饲料又是生产配合饲料的关键。目前,我国新生产的饲料中的蛋白质水平较低,因而饲料报酬也低,影响了畜禽的生长发育.据商业部饲料局统计,若将现有的油料饼和动物蛋白料都用上,尚缺近54亿公斤,到2000年将缺100亿公斤左右.因此解决好蛋白质的来源,是发
With the specialization of breeding industry and the further development of commercialization, the requirements on the quantity and quality of feed will grow and increase day by day. It is far from satisfying the need to produce compound feed by the feedstuff provided by the state, and the protein feed is also used in production Feed the key. At present, the newly-produced feed in our country has a relatively low level of protein in the feed, and therefore the feed remuneration is also low, which affects the growth and development of livestock and poultry. According to the statistics of the Feed Bureau of the Ministry of Commerce, if both the existing oil-cake and the animal protein material are used, It is still short of 5.4 billion kilograms and will be short of 10 billion kilograms in 2000. Therefore, to solve the problem of protein sources,
