The effects of feeding varying
levels of tannia Cocoyam Meals (CCYM) as substitutes for
maize were evaluated on 96, four week-old broiler chicken.
The diets included raw sundried and boiled sundried tannia.
Each form replaced maize at 0, 25, 50 and 100% level. The
differences in weight gain, feed intake and feed
conservation ratio were not significant (P> 0.05) up to 50%
substitution level for both cocoyam diets . The control only
differed from cocoyam diets at 100% substitution indicating
that raw sundried and boiled tannia CCYM has good potentials
in feeding value up to 50% inclusion levels. Feed cost and
cost of daily feed intake significantly decrease (P<0.05)
with increase in the level of CCYM inclusion in boiled and
raw sundried tannia respectively. The level of
anti-nutritional factors (phytate, oxalate, tannin and
saponin) differed significantly (P< 0.01) between the raw
sundried tannia (1.29, 33.32, 1.52, 6.40) and boiled tannia
(0.15, 21.70, 0.14, 4.30). Thus, much better performance
observed on groups fed diets with boiled cocoyam. Possibly
due to heat treatment effects which destroyed the
anti-nutritional factors. Therefore, with proper processing
CCYM could effectively replaced maize at 50% inclusion level
in finishing diets of broilers.
