Effect of adding different levels of gel and coating dried Aloe vera leaves to the diets on Cyprinus carpio performance

This experiment was conducted in the Fish Laborator/ Department of Animal Production/College Agricultural Engineering/University Baghdad for 3 months from 10/21/2020, with aim evaluating use dried Aloe vera leaf and gel powder diets common carp Cyprinus carpio L. In experiment, 18 glass aquariums dimensions 40 x 30 cm (capacity 36 liters) were used, which 90 fish an initial weight 2 ± 45 g/fish distributed randomly over nine treatments two replicates, each treatment, similar rations made protein energy content different percentages added to plant aloe leaves, 0.5, 1, 1.5, 2% gel, as well leaves T2, T3, T4, T5, T6, T7, T8 T9 respectively, addition T1 control treatment that devoid fed on rations. Experimental by 4% its weight. The biochemical characteristics (AST, ALP, ALT), lysozyme ACH50 studied, chemical composition forage analyzed.
