Studies on pathogenesis of bovine mastitis by comparison of milking conditions as calf suckling, hand milking and machine milking: reactions of the teat tissue.

Abstract

From the teat tissue reactions established it is concluded that machine milking causes a higher new infection risk than calf suckling and hand milking
