Protein content and peptides of a newly developed feather meal and other protein feeds
-
摘要: 通过比较自主研发的饲用羽毛肽粉与常规饲料蛋白源鱼粉、羽毛粉、棉籽粕、脱酚棉籽粕、味精生产残渣、豆粕、寡肽鱼溶粉、菜籽粕中不同分子量肽的含量,评估饲用羽毛肽粉在水产养殖饲料中的应用前景。结果表明,不同饲料蛋白源肽分布差异明显,其中饲用羽毛肽粉除寡肽含量低于味精生产残渣外,其他各类肽含量显著高于其他饲料蛋白源。Abstract: To evaluate the prospect of using a newly developed feather peptide meal as a protein feed,the meal's peptide content and distribution were compared with some protein materials including fish meal,feather powder,cottonseed meal,dephenolized cottonseed meal,monosodium glutamate byproduct,soybean meal,fermented fish meal and rapeseed meal.The results showed that the peptide content in the feather peptide meal,except oligopeptides in the monosodium glutamate byproduct,was higher than all others.Its water-soluble protein content was 34.29% higher,acid-soluble proteins 28.29% higher,and oligopeptides 16.30% higher than fish meal.
