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.
