| 摘 要： | 选用均初始体质量为0.91 g的凡纳滨对虾(Litopenaeus vannamei)540尾,随机分为6个处理组,每组设3个重复,每个重复30尾。用肉骨粉(meat and bone meal,MBM)替代日粮中0、20%、40%、60%、80%和100%的鱼粉,分别添加不同梯度微胶囊蛋氨酸(microencapsulated DL-methionine,MM)配制成6种等氮饲料投喂凡纳滨对虾55 d。结果表明:MBM添加MM替代60%鱼粉对对虾增重率和SGR无显著影响(P0.05),对虾对各试验饲料的饲料系数和蛋白质效率无显著影响(P0.05),而替代80%和100%鱼粉对对虾增重率、SGR、饲料系数和蛋白质效率有显著影响(P0.05);MBM添加MM替代鱼粉后对对虾体成分、体氨基酸含量和蛋白质含量无明显影响(P0.05)。在MBM高水平替代鱼粉饲料中添加MM可通过平衡对虾饲料必需氨基酸,提高了对虾对饲料的表观消化率,而不影响对虾的生长和体营养成分,降低了对虾饲料的成本。

| Abstract: | A study was conducted to evaluate the effects of different levels of dietary particulate meat and bone meal (MBM) supplemented with microencapsulated DL-methionine (MM) on the growth, digestibility of feed nutrients, feed utilization, body composition of the shrimp (Litopenaeus vannamei). Five hundred and forty shrimps were randomly divided into 6 treatment groups in triplicate and were fed on six iso-nitrogenous diets formulated by replacing equal nitrogenous fish meal with MM-supplemented MBM by 0, 20%, 40%, 60%, 80%, and 100%for 55 days. Specific growth rates (SGR), digestibility of feed nutrients and feed utilization showed no significantly differences among shrimps when diets contained up to 60% of MM-supplemented MBM (P >0.05), However, such parameters were significantly lower (P < 0.05) for shrimps fed on diets containing 80%?100% of MM-supplemented MBM. Compositions of crude protein, crude lipid and amino acids of shrimps among all groups at the end of the trial were not significantly affected (P > 0.05) by trial diets. It is concluded that MM-supplemented MBM is an acceptable alternative animal protein source, which enhances sapparent digestibility of feed nutrients and decreases feed cost. |
