One hundred and twenty straight run, day old coloured chicken (Chabro) were distributed into four treatments: T1-basal diet, T2- T1+400ppb chromium picolinate (cp), T3- T1+800ppb cp, T4- T1+1600 ppb cp. There was no significant difference on average weekly body weight gain of coloured chicken among treatment groups except in 7th week during which T1, T2 and T3 were significantly higher (p<0.05) than that of T4. FCR was significantly better (P<0.05) in T1, T3 and T4 than T2 at 3rd week. Response to 1% SRBC (log2 titre) and cell mediated immune response to PHA-P were comparatively better in T3 than other groups. There was no significant difference among treatment groups in the carcass quality traits and cut up parts. Thus, it may be inferred that supplementation of 800 ppb chromium picolinate revealed no adverse effect on body weight gain and resulted in higher humoral and cell mediated immune responses in coloured chicken.
