低蛋白饲料的应用,对于种猪由于减少了豆粕等蛋白质饲料的添加量,猪粪尿中氮的排泄量降低。氮素排放量的减少不仅改善了猪生活环境和健康状态,更重要的是减少了对土壤、大气、水源等人类生存环境的污染。育肥猪后期减少磷、铜等矿物质、微量元素在饲料中的添加,能够大大减少这些物质的排放,既节能减排,净化猪饲养环境,又降低对人类生活环境的污染。
The use of low-protein feed, for pigs due to reduced soybean meal and other protein feed added, pig excretion of nitrogen excretion decreased. The reduction of nitrogen emission not only improves the living environment and health status of pigs, but more importantly, reduces the pollution to human living environment such as soil, air and water. Finishing fat pigs to reduce phosphorus, copper and other minerals, trace elements in the feed to add, can greatly reduce the emission of these substances, both energy saving, clean pig breeding environment, but also reduce the pollution of human living environment.
