The present study was conducted to observe the efficacy of water treatment on sorghum grain and to determine its optimum inclusion in broiler diets. Sorghum grain was treated with water and dried. Seven isoenergetic and isonitrogenous diets were prepared, using raw and treated sorghum, and designated diets A, B, C, D, E, F and G. Diet A, containing 0% sorghum, was kept as control. In diets B, C and D, raw sorghum was used at levels of 10%, 20% and 30%, respectively, while in diets E, F and G, treated sorghum was used at the same levels. Two hundred and ten day-old chicks were randomly divided into 21 experimental units of 10 chicks each. These experimental units were randomly allocated to seven treatments. It was observed that water treatment reduced the tannin contents of sorghum. Birds fed diets A, E and F showed the best weight gains, and diet G showed a better weight gain than diets B, C and D. The best feed efficiency was observed in chicks fed diets with treated sorghum compared with those fed raw sorghum. There was no significant effect of treated or raw sorghum on the weight of the internal organs. The study revealed that tannin contents in sorghum grain can be reduced with water treatment and that this treated sorghum can be used in broilers' diet up to the level of 20% to obtain efficient broiler production.
