Reproductive Performance of Domestic Fowl Maintained under Continuous Light.

When domestic fowl were maintained under constant incandescent illumination from time of hatching, the rate of egg production was similar to that of control birds on a diurnal schedule. Hatchability offertile eggs produced by such hens was found to be unaffected by lighting treatment of the parents. Fertility was, however, markedly impaired in the males reared under continuous light. Artificial...

The Rate of Growth of the Domestic Fowl

This paper points out the fact that the growth period of the domestic fowl is analogous to that of the mammal, being composed of three, or perhaps four, cycles; two of these cycles are postembryonic with maxima at about 8 and 18 weeks varying somewhat with the breed and two or at least one, are embryonic with maxima at 11 to 12 and 15 to 16 days of age. Hatching occurs during the first part of ...
