Abstract:
A-Max yeast of Saccharomyces cerevisiae concentrate, Celmanax liquid commercial perbiotic products from Arm & Hammer Animal Nutrition Co. (USA) and probiotic bacilli from protexin Co. (UK) on ammonia and urea-nitrogen excretion in juvenile Common Carp (Cyprinuscarpio) farmed in a rearing culture system. The experimental diets (A-Max, Celmanax and Probiotic bacilli) were mixed with A-Max suspension (A-Max meal in 200 ml of water were mixed with 1 kg of diet), Celmanax (1 ml in 200 ml of water and concentration of 1×1010spors of 5 species of endospore probiotic bacillii,B. licheniformisi,B. subtilis, B. polymyxa, B. laterosporus and B. circulans, were supplemented respectively in 1 kg of diet and dried at 40°C in incubator for 5 h.This experiment was conducted in a completely randomized design with three experimental treatments (A-Max, Celmanax and Probiotic bacilli) and control group with three replicates for treatment and control. Carp juveniles were fed based on the 5-7% of their body weight by experimental diets with experimental dietsand nonsupplemented diet in control group respectively. At the termination of experiment (90 days) fifty fish were sampled and measured the ammonia, urea exceretion and calculated the losing energy in testing plastic tanks.The results showed that the A-Max yeast of Saccharomyces cerevisiae concentrate and Celmanax liquid commercial perbiotic had beneficial effects amount of ammonia and urea excretion of Common Carp (Cyprinuscarpio) juveniles and the losing rate of energy decreasing in comparison with control. The best results in were obtained from supplementation diet of Celmanax liquid.The minimum enrgy losses by ammonia (2.94 KJ/Kg fish/day) and urea (0.68 KJ/Kg fish/day) were obtained in experimental treatment of Celmanax liquid where the Common Carp juveniles fed with supplemented diet with 1 ml of Celmanax liquid per kg of diet.
