Assessment of Thepax and Bio Boost for promoting microbial growth in common carp intestines Cyprinus carpio.

The study aimed to evaluate the effect of Thepax and BioBoost as food additives on microorganisms in intestines fish. From March 4 October 22, total number common carp was 900 fish with an average weight 163.41 ±10.16 g a density 100 fish/cage; three replicates were used for each treatment. fed times daily. included T1(0%additive), T2(1g/kgThepax)and T3 (1 g/kgBioBoost). highest final value is treatment (2209.34 g), followed by Bio Boost control. Microorganisms showed significant differences (P<0.05) T2 Lactobacillus sp. (10² x 65 CFU/ml) 55 control T1 23 CFU/ml), also Cellulomonas 54 39 7 CFU/ml). At same time, Aeromonas bacteria higher 34 over treatments 2 both. We concluded best additive 1 / kg feed recommended diets carp.
