Effect of Feather Peptide Meal on Nutritional Content in Flesh of Darkbarbel Catfish(Pelteobagrus vachelli)
摘要
Abstract
Effect of a feather peptide meal (FPM) on the nutritional value of the flesh of darkbarbel catfish(Pelteobagrus vachelli) was studied.Five formulated diets with 0, 5, 10, 15, or 20% added FPM were fed to the juvenile fish for 60 d.The randomized feedingin triplicate was carried out on 30 individual fish in each group.The results showed no significant differences, among all feeding groups, in the contents of moisture, lipid, protein or ash(P>0.05) in the fish muscles.The contents of essential amino acids(EAA), non-essential amino acids(NEAA), child amino acids(CAA), total amino acids(TAA) and flavor amino acid(FAA) in the fish fed with 10% added FPM were similar to those in the control group (P>0.05), but higher than other groups with added FPM (P<0.05).At 10% addition level, the scores on Lys, EAAI, AAS and CS of the fish flesh were the highest among all fed with added FPM, and close to those ofcontrol.The ratios of E/T and E/N on the muscle protein were higher whenthe fish were fed with less than 10% FPM (P<0.05).Their relative contents of palm acid were significantly lower than those of fish in the groups having FPM added in feed up to 10% (P<0.05).At less than 15% FPM addition levels, the relative contents of SFA and CIS linoleic acid in the fish flesh decreasedsignificantlywith increasing FPM (P<0.05).Up to 10% FPM, the contents of DHA+EPA, HUFA, PUFA and (n-3)PUFA in the fish were higher than all other groups including control (P<0.05).It was concluded that an addition of 10% of FPM could improve the nutritional value of the edible meat from the juvenile P.vachelli fed with the diet.关键词
