Abstract: An experiment was conducted utilizing 180 broiler chicks from day one to 6 weeks of age. These were randomly distributed into four treatment groups of 45 chicks with three replicate having 15 chicks in each, to study the effect of lactobacillus (0.02%) with and without supplementation of live yeast (0.2%) on the live performance carcass traits. From the study it was observed that supplementation of lactobacillus, live yeast alone or in combination had statistically non-significant effect on growth performance, feed consumption, feed efficiency and per cent mortality of chicks. The body weight gain was maximum influenced by live yeast 1437.25±13.45g (T3) followed by combined feeding of lactobacillus and live yeast (T4), and lactobacillus (T2), while least body weight gain was observed by chicks in the control group 1429.72± 14.00g (T 1), respectively. The total average feed consumption through out the experiment (0-6weeks) showed that the maximum feed intake was recorded in T4 group (3285.70g) succeeded by T 3 (3260.34g) and T2 group (3230.78g). Minimum intake was observed in group T1 (3126.43g).Cumulative feed conversion ratio (1-6 weeks) of control (T 1) (2.18± 0.84) was slightly better as compared to Lactobacillus (T 2) (2.25 ± 0.06) because the body weight was comparatively higher in T 2 group as compared to control and the feed conversion ratio is inversely proportional to body weight, but statistically both are non-significant. The feed conversion ratio of T 3 and T 4 group was found to be 2.26± 0.09 and2.28± 0.04 respectively. Thus it was concluded that supplementation of lactobacillus, live yeast alone or in combination had no effect on growth performance, feed consumption and feed conversion ratio.
