尿素是一种简单的氨化物,对家畜没有营养价值,但却能作为细菌的营养。对牛、羊反刍动物,喂尿素可节省蛋白质饲料;但猪为单胃动物,胃中没有尿素水解酶,不能用尿素喂猪。摘自《农家乐》1984.34期. Urea is a simple amide that has no nutritional value to livestock but can act as a nutrient for bacteria. On cattle, sheep, ruminants, feeding urea can save protein feed; but the pig is a monogastric animal, there is no urea hydrolyzing enzyme in the stomach, can not be fed pigs with urea. Excerpt from “farmhouse” 1984.34 period.
