Abstract

This experiment was carried out to evaluate the effect of adding of Microalgae Chlorella and Germinated Barely Powder in diet on growth performance microbiological counts of common carp. The study was assigned to depend on using of natural products as back to nature in fish feeding. The effect of adding microalgae Chlorella and germinated barely powder in common carp Cyprinus carpio diets with different levels for 84 days and the results revealed a significant role of both additives in each of fish Final wt., Wt. Gain, Specific and relative growth rate. No significant differences observed in FCR, the FER was higher significantly in control, T2 with 5 % Chlorella and T4 with 10 % Germinated barely. The total Bacterial and Enterobacteriaceae count/ CFU was increased in the additives treatments with increasing the levels, the T3 with 10 % Chlorella was higher than control and other treatments were 192.5 and 150 respectively. The control treatment without any addition was higher significantly in Total Bacterial count /CFU in common carp intestine samples, the T4 with 10 % Germinated barely was higher in Total Enterobacteriaceae count/CFU in fish Intestine samples. The highest Coliform bacteria in fish muscles and intestine recorded in T5 and the lowest in T3.
