Table I presents data relating to. initial body
weight, weight gain, and feed conversion ratios.
The average chick weight after selection at 1week
of age, for birds under Treatments 1,2 and 3 were
101.1, 100.6 and 100.0 g, respectively. Statistically,they were not different from each other.
Differences in body weight gains were, however,
statistically 'significant (P< 0.05). All the
treatments recorded progressive increment~ in
weight gain. The weight gain per bird for chickens
which had 24-h access to feed (Treatment 1) was
higher than that for the other remaining treatments,
i.e. Treatments 2 and 3. In comparison with birds
which had access to feed at daytime only
(Treatment 2), the body weight gains for those
that had feed only at night (Treatment 3) were
markedly higher.
