Researchers to seek novel strategies to boost, expand turkey breeding
IMAGE: Ashli Moore Reproduction in turkeys is initiated by increased daylength and becomes limited by the onset of “broodiness,” eventually resulting in the termination of egg laying. Hens lose their sensitivity to the reproductively stimulating effects of long days, even under ever-increasing daylengths. Loss of productivity is costly, as birds must be cared for until coming back into production. In birds, photoperiodic information is sensed directly in the brain by specialized photoreceptors. Although the site or sites of these photoreceptors are unknown, scientists have suggested sever...
