Abstract
SINCE the development of Broad Breasted Bronze turkeys, fertility and hatchability have been major problems in the turkey industry. The loss in turkey eggs from these two factors amounts to approximately 40% of all eggs set. Infertility or apparent infertility makes up about two-thirds of this loss.Considerable research work has been carried out in recent years to elucidate the problem of fertility in turkeys in an effort to improve their reproductive efficiency. Since the early work of Burrows and Marsden (1938) which indicated that fertility could be improved in turkeys by using artificial insemination, considerable work has been carried out using this technique as a tool for studying various phases of the fertility problem. Little experimental work is available to indicate the effect of artificial insemination upon fertility in large mass-mated Bronze turkey breeding flocks.McCartney (1951a) showed that artificial insemination gave maximum results in White Holland turkeys when …
