title: Effects of the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), on fertility and hatchability of eggs from artificially inseminated White Leghorn hens.
abstract: Egg production of White Leghorn hens infested with the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), was as much as 15% lower than egg production of control hens. However, when these hens were artificially inseminated with semen from mite infested roosters, fertility nor hatchability was affected by the mite infestation.
