|Abstract ||:||Rearing pullets in summer, when the air temperature and the humidity are usually high
the average temperature being over 30℃. And relative humidity over 80 per cent, I studied
on growth of chicks, feed consumption, and feed efficiency.
The studies were practiced during 6 months from May, 1960, to October, 1960.
1.The pullets of S.C.W. Leghon took 159 days until 30 per cent egg production was
performed. One pullet consumed feed in average of 9.136g during 159 days, the average
live weight being 1.523g. Consequently, the number of kilogram of feed required to produce
a kilogram of gain is 6.0.
2.The pullets of Barred Plymouth Rock, on the other hand, took 185 days until 30 per
cent egg production was performed. The feed consumption during 185 days was 13. 206g, and
the average live weight was 2.231g. Therefore, feed efficiency is 5.9.
The above results show only little difference as compared with those obtained in Cornell
University, New York, and other institutes.
It can be safe to say that a high air temperature and high humidity during the period of
Rearing chicks have little effects on growth of chicks, feed consumption, and feed efficiency.|
