Effects Of Sun-dried Cassava Peel Meal As Replacement For Maize And Wheat Offals On Performance And Nutrient Utilization Of Cockerels

Résumé

Five hundred (590) day-old Hyperco cockerels were raised on four experimental starter diets, A,B,C, and D containing 0, 17.71, 22.30 and 45.64% sun-dried cassava peel meals (CPM), respectively, as replacement for maize and wheat offals. At the finisher phase, the test ingredient was substituted on weight basis at the rates of 0, 20.41, 24.95 and 51.75%. The calculated cyanide contents of the starter diets were 0, 17.62, 22.19 and 45.41 mg HCN/kg for diets A,B,C and D, respectively, at the finisher phase. The duration of the study was 20 weeks. In the finisher phase, the highest mean daily feed intake values (129.6 and 123.5g/bird) were obtained on diets C and D, respectively, while the least mean values (116.9 and 106.5 g/bird) were recorded on diets A and B, respectively. The ME utilisation increased with increasing dietary energy levels in the starter phase and decreased with increasing dietary energy levels in the finisher phase. The daily nitrogen retained decreased with increasing dietary CPM levels in both phases.
