角蛋白饲料加工新技术

针对当前角蛋白饲料加工存在的问题，提出了一种新的膨化复合角蛋白饲料加工工艺，包括原料配制，生产工艺流程和产品营养成分检测等。饲喂结果表明：采用这种加工工艺生产的复合角蛋白饲料，其蛋白质的质量分数超过７０％，氨基酸含量平衡，营养成分与饲喂效果均优于优质鱼粉，用它代替鱼粉生产配合饲料，可降低成本１０％以上，同时，采用这种技术生产角蛋白饲料不会对环境造成二次污染。

New Processing Technology on Keratinous Material

In view of the problems existing in keratin processing, a new technology is developed to produce compound extruding keratinous feed (CEKF), which including batching, processing and nutritions analysis. Feeding trials show that CEKF contains more than 70% of protein and amino acid are in balance. In addition, it has been shown that this new technology has better results than fish meal in both feed efficiency and nutritions aspects. Using it in compound feed instead of fish rneal, 10% of cost can be reduced and it has no environmental problems.
