title: The effects of semen dosage and insemination frequency on the fertility of brolier breeder hens.
abstract: Sexuality mature commerical broiler breeder pullets were housed singly in laying cages and artifically inseminated with one of three different levels of undiluted pooled semen (0.1, 0.05 and 0.025 ml.) at either of two different frequencies (once and twice a week) in three different trials. The best fertility was obtained by inseminating twice a week with 0.05 ml. of semen. Inseminating once a week with 0.1 ml. of semen did not provide maximum fertility in the stock used in this study.
