abstract

When a fertility problem arises, results of these studies suggest that it is most important to carefully examine insemination procedures. Introducing semen into the oviduct to a depth of a half inch did not lower candling reports in 1964–65; however, very shallow insemination, as in the 1963–64 experiment, resulted in lower candling reports. Weekly insemination gave far better candling reports during the second half of each year's experiments, especially in the 1963–64 season. Growers may find it more profitable to inseminate weekly during the second half of the breeder season. Weekly insemination may be the answer to fertility problems in some flocks. Candling reports with diluted semen were found to be as good as those with undiluted semen in these tests.
