Abstract:
A nine (9) weeks feeding trial was conducted on three hundred (300) day old unsexed Anak broiler chicks were raised on deep litter to determine their carcass characteristics, haematology and serum biochemistry when fed five (5) dietary treatments (T1, T2, T3, T4 and T5 supplemented with 0.1, 0.2, 0.3, 0.4 and 0.5%) synthetic methionine. Birds were divided into five treatments of 60 birds each and three replicates of 20 birds per replicate. At the end of the 8th weeks, six birds were randomly selected from each treatment, two per replicate. The birds were slaughtered for liveweight and various organs weight were determined. For the carcass, there was significant difference (P<0.05) in all parameters evaluated. Live, plucked and carcass weights plus dressing percentage increased with increased levels of methionine inclusion. So also, haematologial indices were not significantly (P>0.05) difference in all parameters measured. Same also, is the serum biochemical that wss not significantly (P>0.05) difference. Therefore, it can be concluded that red sorghum can be used to replace maize upto 100% in the diets of broilers without detrimental effects on carcass and haematological indices.
