Effects of Gracilaria verrucosa, Enteromorpha prolifera, Algae Residue and Fungi Residue on Growth Performance, Serum and Liver Biochemical Indices, Body Composition and Intestinal Histological Morphology of Juvenile Turbot(Scophthalmus maximus L.)
摘要
Abstract
This experiment was conducted to investigate the effects of dietary fish meal replacement by Gracilaria verrucosa, Enteromorpha prolifera, algae residue and fungi residue on growth performance, serum and liver biochemical indices, body composition and intestinal histological morphology of juvenile turbot (Scophthalmus maximus L.). Five isonitrogenous and isolipidic diets were formulated with a basal diet contai-ning 60% fish meal as the control group(fish meal group), and other four diets with 35% fish meal replaced by 10% Gracilaria verrucosa, Enteromorpha prolifera, algae residue or fungi residue and vegetables protein (wheat gluten, corn gluten meal and soybean meal), and they were named as FM, JL, HT, ZZ and JZ groups. Each diet was fed to three replicates of 25 juvenile turbot with an initial body weight of(16.00 ± 0.11)g for 77 d. The results showed as follows: 1)the weight gain rate(WGR)and special growth ratio (SGR)of JL, ZZ and JZ groups were not significantly different compared with FM group(P>0.05). The WGR and SGR of HT group were significantly lower than those of FM group(P<0.05). The feed efficiency ratio(FER)of JL and FM groups was not significantly different(P>0.05),but it in JL and FM groups were significantly higher than that of HT,ZZ and JZ groups(P<0.05). The protein productive value(PPV)of FM group was significantly higher than that of HT,ZZ and JZ groups(P>0.05),but had no significant difference compared with JL group(P>0.05). 2)Crude protein content in whole body of JL and HT groups was signifi-cantly lower than that of FM group(P<0.05). And crude lipid content in whole body of ZZ and JZ groups was significantly higher than that of FM group(P<0.05). The contents of histidine and taurine in muscle of JL, HT, ZZ and JZ groups were significantly lower than those of FM group(P<0.05),and the content of ly-sine in muscle of HT and ZZ groups was significantly lower than that of FM group(P<0.05). No significant differences were found in the activities of serum glutamic pyruvic transaminase(GPT),serum glutamic oxala-cetic transaminase(GOT)and liver GOT(P>0.05). The activity of liver GPT of FM group was significantly higher than that of JL and JZ groups(P<0.05), but had no significant differences compared with HT and ZZ groups(P>0.05). 3)The mucosal fold height of foregut and midgut of JZ group was significantly higher than that of FM group(P<0.05). The mucosal fold height of foregut of ZZ group was significantly higher than that of FM group(P<0.05). No significant differences were found in microvillus height of foregut and midgut a-mong different groups(P>0.05). Above results show that replaced 35% fish meal with 10% Gracilaria verru-cosa, algae residue or fungi residue and vegetable proteins have no adverse effect on the growth performance of juvenile turbot, and the algae residue and fungi residue can improve the development of intestinal histological morphology.关键词
