Abstract
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.
