Abstract:
An experiment was carried out to evaluate the growth and economic effects of cassava flour (CF) as an alternative to maize in diets of local turkeys. A total of 135 day- old unsexed local turkey breed were used. The birds were allotted to 5 treatments (T1 T5). T1 which served as control was a diet without cassava flour, while T2, T3, T4 and T5 were diets in which CF replaced maize by 25, 50, 75 and 100% respectively. Each treatment was replicated three times with each having 9 birds in a completely randomized design (CRD). The experiment lasted for 16 weeks; starter phase (0 8 weeks) and grower phase (9 -16 weeks).Feed and water were offered ad libitum. Results showed that at the starter phase there was no dietary effect (P>0.05) on growth parameters. At the grower phase, above 25%, final live weight was reduced (P<0.05). Daily weight and feed: gain ratio were negatively affected by 100%. The 100% replacement resulted to higher feed intake. At 75 and 100% during starter phase, and 50, 75 and 100% during grower phase gross margin was reduced (P<0.05). Therefore replacing maize with CF by 25% in local turkey diets could be adopted.
