I am waiting for Knersie to chime in on this thread in relation to the subject "Pink-eye". Being very specific, pink-eye is NOT a Breed Problem, however the TENDENCY for Hereford cattle to manifest pink-eye symptoms (which are exacerbated by fly infestation and infection) is more likely to be manifest BECAUSE of the white faces and lack of color AROUND the eyes. Knersie's explanation of the Hereford "Eye Set" can help one understand the Physiology of the skeletal structure of the head and the shading effect that the eye BROWS (bone structure) and lashes provide in reducing infra-red and ultra-violet inflamations and irritations.
Think about it.
