棉籽饼粕及棉籽制油后的副产品,含有丰富的蛋白质、氨基酸(表1)是畜禽良好的蛋白质补充料。我国棉籽饼粕数量可观。据1984年统计,年产棉饼粕42.5亿公斤,居各类饼粕之首。但长期以来,我国棉饼粕利用极不合理,绝大部分棉饼粕用作肥料,用于饲料的只占一小部分。据武汉市郊县统计,利用不过10%,就湖北省而言,年产棉、菜饼4.6亿公斤,1982年利用率(用于饲料的比率)为0.31%,1985年利用率也只有4.15%。导致这一后果的原因是多方面的,首先是人们的思想认识问题,对开发棉饼蛋白质资源的重要性认识不足,畜牧业落后,也是个重要原
Cottonseed meal and cottonseed oil by-products, rich in protein, amino acids (Table 1) is a good animal protein supplements. China’s cottonseed meal volume is considerable. According to 1984 statistics, with an annual output of 4.25 billion kilograms of cotton cake meal, ranking first in all kinds of cakes. However, for a long time, the utilization of cotton cake in our country is extremely unreasonable. Most of the cotton cake is used as fertilizer, and only a small part is used for feed. According to the statistics of Wuhan suburban counties, the utilization rate is 10%. In terms of Hubei Province, the annual output of cotton and vegetable cakes is 460 million kilograms. In 1982, the utilization rate (for feed ratio) was 0.31%, and the utilization rate in 1985 was only 4.15 %. The reasons leading to this are many. First is the problem of people’s ideological understanding. They also do not know enough about the importance of developing cotton cake protein resources, and animal husbandry is also an important factor
