Evaluation effect of dietary egg lecithin on digestive enzymes and body composition of juvenile binni (Mesopotamichthys sharpeyi Gunther, 1874)
2015
In this study, the effects of dietary egg lecithin on digestive enzymes and body biochemical composition of juveniles Mesopotamichthys sharpeyi was evaluated. Four experimental diets including control diet (with 0% egg lecithin) and three diets containing 2%, 4% and 6% egg lecithin were used. At the end of the experiment, digestive enzymes activity (lipase, amylase and alkaline phosphatase) and body biochemical compositions were assessed. The results showed no significant differences between experimental treatments in moisture and ash content. Maximum content of the crude protein and crude lipid were recorded in 4% lecithin treatment and it had significant differences with control group. The digestive enzymes activity (lipase, amylase and alkaline phosphatase) showed significant differences between control and experimental groups. An increasing trend was observed in the digestive enzymes activity among treatments. Based on the results, it was concluded that 4% to 6% dietary egg lecithin in the diet, can promote growth and survival rate of juvenile binni.
