Abstract

Investigations on 5016 hens revealed that the best reproductive performance was attained when birds were inseminated each with 0.02 ml semen between 14.00 and 20.00 h, at intervals of 6-7 days, compared with intervals of 3-4, 4-5 and 10-11 days. Egg fertility and hatchability were better following ...
