3.4 Effect of Different Pearl Millet Inclusion Levels on Feed
Digestibility
Digestibility results showed that the diet with pearl millet as the sole energy source
has significantly (P < 0.001) lower digestibility (64.73%) than the rest of the other
treatments which were similar (0% pearl millet = 82.34%; 10% pearl millet = 81.83%; and 20% pearl millet = 81.5%). In general, digestibility tended to
reduce with increasing inclusion levels of pearl millet.
3.5 Effect of Pearl Millet on Productivity Cost
1
Taking variable costs into consideration, the average cost per broiler was MK1492.5
($2.06), MK1512.20 ($2.09), MK1531.90 ($2.11), and MK1619.70 ($2.23) for
treatments 1, 2, 3, and 4, respectively. Cost per broiler tended to increase with
increasing levels of pearl millet used. Using an average selling price of MK2800
($3.86) per whole carcass as farm gate price, the results show that the sole maizebased diet (T1) had the highest gross margin.
