Abstract

In a herd of 127 dairy Friesian cows, ppst-partum metritis developed in 50 animals (39.3%) and was associated with clinical mastitis. The incidence of primary mastitis in the herd was 12%. The results indicated that secondary mastitis which developed in association with metritis was about four times of primary mastitis. The present information seems to be of importance when attempting to plan a control against mastitis.
It is suggested that quarter infection was facilitated through a heamtogenous invasion of bacteria to the devitalised mammary tissue and sets up secondary mastitis in cows with infectious metritis.
