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.
