Abstract	Two hundred and forty (n=240), day-old broiler chicks of strain ‘cobb400’ were divided equally into 3 groups of 80 chicks each in group to observe the effect of probiotics (Protexin) supplementation on growth performance and economics of feeding in broilers. Different dietary treatments were T1–basal diet without probiotics supplementation (control), T2–T1 + probiotics supplementation (50 g/ton of feed) and T3– T1 + probiotics supplementation (100 g/ton of feed). Average daily body weight gain (BWG) was significantly higher (P≤0.01) in T3 compared to T2 and T1 (41.63 ± 0.25 g vs 39.48 ± 0.15, 39.99 ± 0.10). Feed intake during starter, finisher and overall study period remained statistically (P≥0.05) at par. Feed conversion ratio was significantly (P≤0.01) improved with probiotics supplementation @100 g/ton of feed compared to control. Dressing percentage and organ weights (% Body Weight) remained statistically (P≥0.05) similar. Mortality (%) was lower for group T3 (1.25) compared to T2 (3.75) and T1 (5.00) but differences were non-significant (P≥0.05). The return over feed cost was significantly (P≤0.01) higher in T2 (`30.99) compared to T1 (` 27.82) and control (` 26.45). The profit per bird over control in group T2 and T3 was ` 1.37 and ` 4.54, respectively. Thus, the dietary supplementation of probiotics at 100 g/ton of feed significantly enhanced body weight gain along with better feed conversion ratio and profit without any adverse effect on feed intake, mortality and carcass characteristics.
