The effects of feeding broiler chickens with millet, low tannin and high tannin sorghum baseddiets compared to maize- based diet on the carcass measurements and blood constituents was investigated in the semi-arid zone of Nigeria. Two-week (14 days) old broiler chicks (Anak 2000) weighing averagely 351.7±5.67 were randomly allotted to four experimental diets in which maize (T1) control, millet (T2), low-tannin sorghum (T3) and high tannin sorghum (T4) served as the energy sources in a randomized complete block design (RCBD). Each treatment contained 45 birds with three replicates of 15 birds each. Except for breast, full crop and abdominal fats, there were no significant (P> 0.05) differences among all the treatment groups for carcass and organ measurements. Packed cell volume (PCV), red blood cells (PBC) count and lymphocyte values were significantly (P< 0.05) higher in the maize (T1), millet (T2) and low tannin sorghum-based (T3) diets than the high-tannin sorghum based diet (T4). Mean corpuscular haemoglobin concentration (MCHC), basophils and neutrophils values were however, inferior (p<0.05) in the maize (T1), millet (T2) and low-tannin sorghum based (T3) diets compared to the high-tannin sorghum based (T4) diets. Blood protein and blood sodium were better (P< 0.05) in the sorghumbased diets (T3 and T4) than those of maize and millet-based diets. This study therefore revealed that replacing maize with sorghum or millet has no adverse effects on carcass and blood constituents of broiler chickens.
