Abstract

The major challenges of cassava supplementation in poultry diets are high cyanide and low protein content. This study was conducted to evaluate the nutritional value of maize-cassava diets supplemented with methionine and inorganic sulphur for broiler chickens. A total of 270 one day-old broiler chicks were randomly assigned to nine treatment groups of 30 birds with 10 birds per replicate. Starter and finisher diets were formulated  and fed for a period of 56 days. Dietary treatments were subjected to completely randomized design. The birds were fed diets supplemented with 0, 125, 250 mg/kg DL-methionine and 0, 125, 250 mg/kg inorganic sulphur from CuSO .There was a linear increase in final weight (FW) and total weight  gain 4 (TWG) w th supplementation of 125mg/kg DL-methionine across dietary sulphur levels at the starter phase. Birds fed diets  supplemented with 125 mg/kg DL-methionine and 250 mg/kg inorganic sulphur showed higher (p<0.05values of 463.23g, 424.66g and 2.66 for FW, TWG and feed conversion ratio respectively. The finisher phase followed a similar trend. Carcass yield showed significant (p<0.05) improvement in dress weight, cut part and organ weight in birds fed diets supplemented with 125 mg/kg DL-methionine and 250 mg/kg inorganic sulphur. The findings revealed that birds with diets supplemented with125 mg/kg DL-methionine and 250 mg/kg inorganic sulphur showed improved growth performance and carcass yield. In conclusion from this study supplementation of DL-methionine and inorganic sulphur in diets for broiler chickens resulted in improved growth performance and carcass yield.
