摘    要:分别以豆粕或鱼粉加豆粕为主要蛋白源配制等氮、等能的豆粕基础饲料或鱼粉饲料,并在豆粕基础饲料中分别添加不同水平的羟基蛋氨酸钙(MHA-Ca)(0.045%、0.090%、0.135%和0.180%)作为实验饲料。以基础饲料组和鱼粉组为对照,饲喂鲤(47.12±2.54)g8周,测定实验鱼的体长、体重,并计算存活率、相对增重率、相对增长率、饲料系数和蛋白质效率。同时取实验鱼的白肌,测定其水分、粗蛋白、粗脂肪和粗灰分的含量。结果表明,0.135%MHA-Ca组的相对增重率和相对增长率显著地高于豆粕基础饲料组(P〈0.05),但与鱼粉组和其他MHA-Ca组没有显著性差异;在豆粕基础饲料中添加0.135%MHA-Ca,饲料利用效率和蛋白质效率显著地增加(P〈0.01),但饲料系数和蛋白质效率与鱼粉组之间无显著性差异(P〉0.05)。同豆粕基础饲料组相比,0.090%和0.135%MHA-Ca组鲤肌肉蛋白质含量显著增加(P〉0.05),但与鱼粉组相比无显著性差异(P〉0.05)。同豆粕基础饲料和鱼粉饲料相比,豆粕基础饲料中添加不同水平的MHA-Ca对鲤白肌中水分、脂肪、灰分含量无显著影响(P〉0.05)。

关 键 词:  羟基蛋氨酸钙(MHA-Ca)  相对增重率  白肌营养组成

Abstract:Two isonitrogenous and isocaloric soybean meal basal diet and fish meal plus soybean meal diet were formulated as control diets.The soybean meal basal diet was supplemented with different levels of calcium salt of 2-hydroxy-4-(methylthio) butanoic acid(MHA-Ca)at 0.045%,0.090%,0.135%,and 0.180%,respectively.After eight weeks feeding,weight gain,length gain,feed conversion rate,and protein efficiency ratio of common carp were determined.Moisture,crude protein,crude lipid,and crude ash in white muscles of common carp were measured.The weight gain,length gain,and protein efficiency ratio of carps fed 0.135% MHA-Ca diet were significantly higher than those of fed soybean meal basal diets(P<0.05),but were not different from those fed fish meal diet.Feed efficiency(feed:gain ratio) of the 0.135% MHA-Ca group was significant lower than the soybean meal control group(P<0.01),and not different from the fish meal group (P>0.05).Compared to the soybean meal basal diet,diet supplemented with 0.090% and 0.135% MHA-Ca resulted in significant higher protein content in the white muscle(P<0.05),but it was not different from the fish meal diet(P>0.05).Dietary supplementation with different levels of MHA-Ca had no significant effect on the moisture, fat,and ash content in the white muscles of common carp relative to the soybean meal basal diet or fish meal diet(P>0.05).
Keywords:common carp(Cyprinus carpio)  calcium salt of 2-hydroxy-4-(methylthio) butanoic acid(MHA-Ca)  weight gain  nutrient composition of white muscle
