Abstract A study was conducted to observe the effects of dietary supplementation of probiotics on broiler chiken. Day old chicks (n=240) were randomly distributed in one of four dietary treatments, viz. C (Control, basal diet only), T1 (probiotic at 0.02% of diet), T2 (probiotic at 0.025%) and T3 (probiotic at 0.03%). The probiotic supplement was used in the form of Lacto-Sacc (Alltech, Bangalore) that contained live yeast culture (Yea Sacc1026 4.49×109, Lactobacillus acidophilus 108 and Streptococcus faecium 108 per gram). Results obtained from the six week study revealed that supplementation of probiotics at varying levels to the broiler chicken yielded positive effects on growth performance (3.28–4.03 per cent higher body weight than control) in broilers such as increased body weight gain, feed efficiency, protein efficiency and performance index and the best effect was observed for the supplementation at 0.025% level. However, there was no significant effect on haematobiochemical parameters assessed at six weeks of age except serum cholesterol level (mg/dl) which was significantly (P<0.05) lower in probiotic supplemented groups T3 (156.94±0.42), T2 (157.56±0.61), T1 (158.15±0.51) than control (174.78±0.57) group. It is concluded that probiotic supplementation at different level in poultry diet has beneficial effect on growth performance.
