Citation: de la Cruz CPP (2016) Production performance of finisher broiler fed with cocoyam-corm meal as partial energy replacement for maize, Veterinary World, 9(10): 1107-1112.

Aim: The objective of this study was to evaluate the potential of Gabing San Fernando (Xanthosoma spp.) corms as partial carbohydrate replacement for maize in finisher broiler production.

Materials and Methods: The completely randomized design was utilized to investigate the effects of three finisher poultry diets prepared in varying amounts of cocoyam-corm meal set at 0% (control), 25%, and 50% (experimental) replacement levels.

Results: There were no significant differences (p≥0.05) as to mortality and body weight measurements between control and experimental groups. Similarly, the mean weights of selected internal organs and condemnable carcasses among treatment groups did not show any significant differences (p≥0.05). In terms of the average feed intakes, birds from 50%-cocoyam group had the highest mean value and were found to be statistically different (p≥0.01) from both control and 25%-cocoyam groups. However, feed conversion ratio did not significantly differ (p≥0.05) among three groups. Higher feed costs were associated with the 50%-cocoyam treatment diet, which was only consistent with higher feed inputs. Thus, the group fed with 50%-cocoyam meal had significantly higher total mean production costs (p<0.005) per bird, when other expenses were taken into account. The production costs for the group given 25%-cocoyam meal did not significantly differ (p≥0.05) from the control group.

Conclusion: Partial replacement of maize with cocoyam-corm meal at 25% level was acceptable since inclusion at this level did not adversely affect the production performance of finisher broilers in terms of growth rate, mortality rate, and feeding efficiency. The use of cocoyam meal as nonconventional and alternative carbohydrate source in poultry diet presents positive economic implications, especially to smallhold farmers from the developing countries, like the Philippines.
