Effects of the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), on egg quality of White Leghorn hens. 1981

J A Devaney

Interior egg quality and shell thickness of eggs from hens infested with the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), were compared with eggs from mite free hens. Egg shells of mite infested hens were significantly thicker (P greater than or equal to .05) but within the normal biological range. There were no differences in either Haugh units or yolk color between the two groups of hens.
