The viability of bacteria in seven probiotic products for animal production available in Bangladesh namely Bactosac, Micro guard, Probac, Poultry Star sol, Gutpro, Clostat 11 and Rumilac were tested. All the products were purchased in local markets. The bacteria in the probiotic product were grown anaerobically using Luria-Bertani (LB) broth and incubated for 13 h at 37° C. The viable bacteria of commercial probiotics ranged between 6.8 ×102 to 2.0×104 cfu/g. The highest values (2.0×104 cfu/g) were found in Microguard and Probac and the lowest value (6.8 ×102) was found in Gutpro. However, viable cells in Microguard and Probac were found lower by four and three logarithmic cycles, respectively, than manufacturer statements (5.0×108/g and 3.0×107/g). The viable cells found in the probiotic products were not accepted as the minimum level of 106 cfu/ml or cfu/g. The results of the present study concluded that viability of bacteria in commercial probiotic products were not found at a minimum level and therefore may not be sufficient for colonization of the animal gut.
