As result shows in Table 1, Probiotic supplementation had increased mean daily body weight gain significantly throughout the experimental period (P < 0.05). The highest mean body wt gain was observed in treatment 4 as compared with treatments 2 and 1 (P < 0.05). The highest and the lowest feed intake were observed in treatments 1 and 4, (P < 0.05). Feed intake was low, when the levels of probiotic reduced in the diet at the finishing stage. Mean feed efficiency was affected by inclusions of high level of probiotic. Therefore, better feed efficiency at the trail period was referred to treat-ment 4 (P < 0.05). This finding was in accordance to the previous research work 7. Production index (PI) is a very important criterion as point of view to the producers. As results revealed probiotic had significantly effect on production index in treatment 4, (P < 0.05). Carcass and body wt. are having positive correlations, since supple-mentation of probiotic improved carcass percentage. The higher mean live body wt. was observed in treatment 4, subsequently which were considered better carcass per-centage and remain non-significant 8.
