目前全国优质牧草市场缺口达300万吨。到本世纪末,全国牛存栏数将达1.57亿头,羊存栏数将达3亿只。年出栏率分别为4120万头和2.14亿只。同时,全国范围内广阔开展起来的特种养殖热潮,对优质高产牧草的需求量极大。当今世界饲料发展趋势是重视发展青绿饲料,研究并发展高产优质的饲料作物,以提高单位面积的畜产品产量。
At present, the gap of high quality forage market reaches 3 million tons. By the end of this century, the number of cattle in the country will reach 157 million and the number of sheep kept will reach 300 million. The annual slaughter rates were 41.2 million and 214 million respectively. In the meantime, there is a huge demand for high-quality and high-yielding forage for the special cultivation boom broadly launched nationwide. The trend of feed development in the world today is to pay attention to the development of green feed, to research and develop high-yield and high-quality feed crops to increase the output of livestock products per unit area.
