Abstract
Sexually mature males of a commercial chicken meat-type strain were exposed to a single daily photoperiod of 15.5, 14, 6 or 2 h over a 5-mo period. The fertility of males on the 2-h photoperiod was significantly less (P < 0.05) than that of birds on other photoperiods. Although males on the 6-h photoperiod had significantly lower spermatozoa motility, viability was unaffected (P < 0.05). It is concluded that the 6-, 14- and 15.5-h photopheriods supported optimum fertility for meat parent males.
