Effects of Three Plant Protein Sources on Growth and Muscle Nutrition of Monopterus albus

On the same addition level of fish meal,soybean meal,cotton seed meal and rapeseed meal were used to make three iso-nitrogenous diets(38% crude protein level),and feed the Monopterus albus.The results showed that between soybean meal group,cotton meal group and rapeseed meal group,there was a significant difference on growth and feed utilization rate of M.albus(P0.05).The growth performance and feed utilization rate of soybean meal were significantly higher than the cotton meal group and rapeseed meal group,and the rapeseed meal group was the worst.There was no significant difference of condition factor、VSI and HIS among three experimental groups,and the VSI and HIS of soybean meal group was highter than cotton meal group and rapeseed meal group.There was some effect on muscle nutrition of M.albus for the three plant protein sources.The crude protein content of soybean meal group was higher than cotton seed meal and rapeseed meal,but the crude fat content was lower than the cotton seed meal and rapeseed meal,indicated the soybean meal had higher nutrition value.
