Abstract
An experiment was conducted to investigate the effect of rapeseed meal (RSM), sunflower meal (SFM), canola meal (CM) and guar meal (GM) respectively at 50, 60, 100 and 50g/kg in a maize soyabean based diet on growth performance, plasma mineral concentration, bone mineralisation and mineral digestibility in broiler chickens. The control diet had soya bean meal (SBM; 320g/kg). Day old Hubbard broilers were allocated to five treatments each with 4 replicates and 10 birds. Partial replacement of SBM with other protein sources resulted in heavier (P<0.05) birds compared to control. Bone mineralisation was not affected (P>0.05) by diets. Plasma Ca concentration was higher (P<0.05) in birds fed GM compared to all other treatments. Retention of P, Mg, Na, Cu was increased and Ca retention was decreased in birds fed control diet whereas, no differences (P>0.05) were observed between treatments in K, Fe and Mn retention values. In conclusion, alternative protein sources improved growth but had variable effects on mineral utilisation.
