An experiment on 120 day old Ross 308 broiler chicken was conducted to study effect of dietary supplementation of minerals (Se + Zn + Cr) on growth performance and carcass yield. Chicks were divided into three groups of 40 chicks in each and dietary treatments consisted of minerals (Sodium selenite, Chromium picolinate, Zinc-methionine) in three levels. Group T1 was without additional supplementation minerals, group T2 was supplemented with minerals Se + Zn + Cr @ 0.15 + 25 + 0.30 ppm and group T3 was supplemented with minerals Se + Zn + Cr @ 0.20 + 50 + 0.50 ppm, respectively. In T3 group, cumulative feed intake was significantly (p < 0.05) low compared to T1 during 42 days of experiment. However, cumulative intake was significantly (p < 0.05) lower in T3 compared to T2 upto 28 days, but later the value remained similar. Weight gain in T3 was significantly (p < 0.05) higher on day 28th and 42nd as compared to other groups. The T3 group had best feed: gain ratio as compared to other groups (p < 0.05). Weight of dressed meat, wing piece, thigh and breast were significantly p < 0.05) higher compared to other groups. Thus, minerals supplementation improved growth performance, dressing percentage and total carcass yield in T3 group as compared to T1 and T2.
