PERFORMANCE AND SERUM METABOLITES OF BROILERS FED VARIED LEVEL OF CASSAVA PEEL MEAL ENRICHED WITH METHIONINE AND ENZYME

Résumé

The high dietary fibre and low energy density of cassava peel have limited the full utilization by broiler chicken. Supplementation of cassava peel with enzymes and methionine improve broilers performance. Performance and serum metabolites of broilers fed varied level of cassava peel meal (CPM) enriched with methionine and enzyme was studied. A total of 96 broiler chickens were used in the research work. The birds were randomly allotted to four experimental treatment with each treatment having four replicate of eight birds per replicate. A completely randomized design (CRD)
was employed. Four experimental diets were compounded to include CPM at 0, 15, 30 and 45% maize replacement in diets designated as T1, T2, T3 and T4. Performance and serum metabolites parameters of broilers fed were determined. Observed results show no significant differences (P>0.05) in initial weight and feed conversion ratio (FCR). However, there were significant variations (P<0.05) in final weight, weight gain, daily weight gain and daily feed intake in the performance parameters. A significant difference (P<0.05) was observed for total protein, albumin, creatinine and cholesterol. A non-significant difference (P>0.05) was observed for globuline, aspartate amino transferase and alanine amino transferase. Values of the total protein was significantly different (P<0.05). However, no significant variation were observed for the values obtained in the birds fed diets T1, T2 and T3, except for cholesterol which were significantly reduced with CPM inclusion. It was concluded that CPM be included up to 30% replacement for maize in the diets of finisher broilers chickens.
