| Purpose: the purpose of this study was evaluate the effect of different levels of two commercial prebioticA-Max Ultra and celmanax liquid different levels ofgrass carp larvae on growth performance, feeding efficiency and ammonia, urea excretion and energy losing in grass carp (Ctenophryngodon idella) larvae for 45 days. Method: For this purpose, 1200 fish larvae with average mean weight 625.15±10.12 (mg)was fed with dietsupplementation1, 2 and 3 g.kg-1Under the titles of A1, A2 and A3, and three levels of Celmanax liquid prebiotic1, 2 and 3 cc.kg-1 of ration) under the title of C1, C2, and C3 and effect of them compared with the control group (diet without prebiotics). The feeding of larvae was considered at 4 percentage of the body weight during the course of the test,but in during of excretion test feeding of larvae were completely interrupted. Results: The results showed that at the end of experiment the use of both commercial products, had significantly improved the growth parameters and feeding efficiency in experimental treatment than the control group (p>0.05).However, there was no significant difference between experimental groups internally regarding nutrition indices (p> 0.05).Also, ammonia excretion, urea excretion and the losing rate of energy of grass carp larvae significantly decreased in experimental treatments (p<0.05). Conclusions: Finally, our results confirm the potential of prebiotic A-Max Ultra and celmanax liquid had promoted effects on enhancement of growth parameters and feeding performancein experimental treatments and prebiotic’s can reduce ammonia and urea excretion in Ctenopharyngodon idella larvae. |
