Abstract

 

A 56 - day feeding trial was conducted to determine the growth performance and nutrient digestibility of broiler chickens fed diets containing red sorghum (RS) and white Sorghum (WS) with or without tannase supplementation. A total of 240 one day old unsexed Arbor acre broiler chicks were randomly assigned to eight (8) dietary treatments which were divided into 3 replicates each of 10 birds in a randomized completely block design 4x2 factorial arrangement. Eight (8) diets were formulated in which sorghum replaced maize at 0, 100 RS, 100 WS and 50RS:50WS% at the starter and finisher phases. The first 4 diets (diets 1, 2, 3 and 4) were formulated without tannase then the other 4 diets (diets 5, 6, 7 and 8) had the same composition as diets 1, 2, 3 and 4 but supplemented with tannase. Growth performance data was collected on weekly basis and nutrient digestibility was determined at the 28th and 56th day for starter and finisher phases respectively. Starter birds fed 100%WS diet and those fed 50RS:50WS tannase supplemented diet had the highest (P<0.05) final weight and weight gain. There was no significant (P>0.05) difference in the growth indices of the finisher birds except the total feed intake which was highest (P < 0.05) in birds fed 50RS:50WS% diet without tannase. Although, finisher birds fed the control diet with tannase had the least feed intake, those fed the control diet without tannase had the best FCR. None of the nutrient digestibility indices were significantly (P>0.05) influenced at the starter phase except the crude protein retention which was highest (P< 0.05) in finisher birds fed 100%RS diet supplemented with tannase. In conclusion, 100% WS without tannase and 50RS:50WS with tannase may replace maize in starter broilers diet while 100% RS and 100% WS with or without tannase may replace maize in finisher broilers diet for optimum performance and nutrient digestibility without any deleterious effect. Similarly, the addition of tannase to the control diet also enhanced performance and nutrient digestibility.
