【摘要】 135型羽毛膨化机膨化的羽毛粉营养价值较高，粗蛋白含量在79％以上，而且精氨酸、异亮氨酸和胱氨酸相对较高。用蛋公鸡测得表观代谢能值为15.1兆焦/千克，蛋白质消化率可达78.37％，因此膨化羽毛粉是禽饲养中比较好的动物性蛋白质饲料。更多还原

【Abstract】 The expanded feather meal produced by 135－type feather expander is nighly nutritive,which contains more than 79％crude protein (cp)and high content of arginine,isoleucine and cystine as well.The experiment of egg－type cockerels indicated that the apparent metobolizable energy(AME) is 15.1MJ1kg;protein digestibility is up to 78.37％.So expanded feather meal is a good kind of animal protein materials in poultry feed.更多还原
