Abstract
Mammary gland lesions characterized primarily as mammary teat atresia were observed in a Limousin beef cattle herd in eastern Texas. Atresia of multip le teats per mammary gland was reported in first-calf heifers at the time o f calving. Pathogens were not identified in eight mammary glands collected at slaughter Histology of affected glands demonstrated superficial and deep perivascular inflammation and fibrosing dermatitis of teat and mammary gla nd skin that resulted in formation of the atretic lesions of glandular tiss ue. institution of a horn fly (Haematobia irritans irritans (L.)) control p rogram using insecticide-impregnated ear tags was associated with eliminati on of the problem from the herd.
