of energy in grower chickens diets while another was conducted to determine
the effect of SPM on the performance of the birds used in the grower study.
A total of 210 pullets aged 10 weeks of Shika Brown breed were used for the
grower study, while a total of 180 chickens aged 23 weeks acquired from the
proceeds of the first study were used for the layer study. Five treatments comprising
of diets containing 0, 10, 20, 30 and 40% levels of SPM were applied in both
experiments in a completely randomized manner and performance of birds were
monitored at both phases. Each of the experiments lasted 12 weeks. Result of
grower study showed that the control, 10 and 20% SPM diets produced similar
weight gain, final weight, feed efficiency and feed cost kg-1 weight
gain and were superior (p<0.05) to 30 and 40% SPM diets. Result of the layer
experiment showed that the control, 10 and 20% SPM diets produced similar final
body weight, weight gain, feed intake, hen-day egg production and cumulative
egg production/bird which were significantly better (p<0.05) than those produced
by the 30 and 40% SPM diets. Ages at 1st egg and at 5% production were least
(p<0.05) for the control birds while the age at 50% production was least
for the 10% SPM diets. From the result, it is inferred that grower chicken or
young layers should not be fed with diets containing more than 20% SPM.]]>Afolayan, S.B.,20102010Afolayan, S.B., I.I. Dafwang, T.S.B. Tegbe and A.
