摘要
本文对比研究了棕仁粕、豆粕、花生粕的基础营养及体外胃蛋白酶消化性,通过在实验饲料中添加2%、6%、10%的棕仁粕制备了四份等氮等能的饲料,初步评价了添加棕仁粕对罗非鱼生长、体组分以及血清学参数的影响。结果表明:棕仁粕作为蛋白水平相对略低,纤维含量较高的植物蛋白替代源,其体外胃蛋白酶消化率与豆粕和花生粕无明显差异,可以作为膳食饲料组分适量的添加到水产动物饲料中,而不会影响罗非鱼的正常生长;在罗非鱼养殖实验中,添加2%棕仁粕的饲料组,罗非鱼的增重率,饲料系数,蛋白利用率、鱼体的蛋白组分以及血清学参数与对照组相比无显著差异(P>0.05),添加至6%～10%后,罗飞鱼的生长表现开始下降,饲料系数开始上升,鱼体蛋白组分下降(P<0.05)。作为棕仁粕在水产养殖领域的初步探索性应用研究,研究认为棕仁粕是可以用于水产饲料的成分使用的,添加比例不宜超过6%。
A preliminary study was conducted to evaluate the basal nutrition and pepsinum digestibility in virtro of Palm kernel meal,soya bean meal and peanut meal.In addition,the palm kernel meal（PKM） was graded and supplemented in a commercial diet to evaluate the effect on growth,feed utilization,body composition,serologic index of juvenile Nile tilapia.Results showed that PKM had relatively low protein content and high fibre content.There were no significant difference in vitro pepsinum digestibility（P0.05）.In feeding experiments,growth performance,feed conversion ratio,body protein composition and serologic index of juvenile Nile tilapia were not affected until PKM was added up to 6%（P0.05） as a result of the decrease of feed protein level and digestibility of enteric canal to protein.In conclusion,PKM can be added into fish feed diets no more than 6 %and it was favorable to make further efforts on the utilization of PKM in aquaculture.
