The aim of the present study was to evaluate the effect of addition of Lactobacillus fermentum in drinking water on performance and carcass characteristics of broiler chickens. The experiment was conducted on hybrid combination Hubbrad JV (n=120). The feeding period lasted 42 days. Experimental group of chickens (n=60) received probiotic strain Lactobacillus fermentum CCM 7158 with a concentration of 1 x 109 colony forming units (CFU) in drinking water from day 1 to day 42 of fattening. The control group of chickens (n=60) received water without any additives. The supplementation of Lactobacillus fermentum CCM 7158 affected positively final body weight of broiler chickens (2 060.56 vs. 2 255.49 g; p less than 0.01) and total feed consumption (1.74 vs. 1.80 kg). Mortality was similar in both groups (6.67%). There were no significant differences (p great than 0.05) between groups in carcass yield, percentage of breast and thigh. Statistically significant differences were determined in slaughter weight (2 049.13 vs. 2241.39 g; p less than 0.01) and weight of abdominal fat (41.67 vs. 33.58 g; pless than 0.05).
