Appropriate Ratio of Fish Meal Substituted by Dephenolized Cottonseed Protein Compound in Diets of Monopterus albus under Adding or Non-Adding Complex Enzyme Preparation Conditions
摘要
Abstract
To explore the appropriate ratio of dephenolized cottonseed protein compound of fish meal substitu-ted by dephenolized cottonseed protein compound in diets of Monopterus albus under adding or non-adding complex enzyme preparation,a basal diet containing 50％fish meal was prepared as a control,and then three experimental diets were prepared with dephenolized cottonseed protein compound instead of 25％,50％and 100％fish meal in the basal diet,respectively.Next,At the corresponding replacement level,three enzyme-containing experimental diets were prepared by adding 0.1％complex enzyme preparation to the three experi-mental diets.Eels[(8.774±0.023)g]were fed above seven diets for 60 days.The results showed as follows:1)the final average body weight,weight gain rate,specific growth rate,protein efficiency,protein deposition rate increased firstly and then decreased with the increase of the replacement ratio of dephenolized cottonseed protein compound;with the specific growth rate and protein efficiency as evaluation indexes,the appropriate ratios of dephenolized cottonseed protein compound to replace fish meal were 27.47％and 39.62％under non-adding complex enzyme preparation,and were 42.70％and 50.79％under adding complex enzyme prepara-tion,respectively.2)The replacement of 25％or 50％fish meal with dephenolized cottonseed protein com-pound had no significant effect on the condition factor of Monopterus albus under the adding or non-adding complex enzyme preparation conditions(P＞0.05).3)Under the same replacement ratio,the activities of di-gestive enzymes in each tissue in the adding complex enzyme preparation group were higher than those in the non-adding complex enzyme preparation group.4)Under the adding or non-adding complex enzyme prepara-tion conditions,the crude protein content of whole fish in the 25％replacement group was significantly higher than that in the control group(P＜0.05),and it in the adding complex enzyme preparation group was higher than that in the non-adding complex enzyme preparation group under the replacement ratio of 25％(P＞0.05).5)Under adding complex enzyme preparation condition,the muscle adhesion in the 25％replacement group was significantly higher than that in the control group(P＜0.05).6)Under the same replacement ratio,the ac-tivities of alanine aminotransferase and aspartate aminotransferase in serum were decreased,and the contents of high-density lipoprotein and low-density lipoprotein in serum were increased by adding complex enzyme prepa-ration.7)Under the conditions of adding or non-adding of complex enzyme preparation,the replacement of 25％ fish meal with dephenolized cottonseed protein compound had no significant effects on the villus length and lamina propria thickness of the foregut and hindgut of Monopterus albus(P＞0.05).The results indicate that adding complex enzyme preparation can promote the digestion and utilization of dephenolized cottonseed protein compound in Monopterus albus.The appropriate ratios of fish meal substituted by dephenolized cotton-seed protein compound for short-term(60 days)feeding of Monopterus albus are 27.47％and 42.70％under the conditions of adding or non-adding of complex enzyme preparation,respectively.[Chinese Journal of Ani-mal Nutrition,2023,35(12):7953-7968]关键词
