Today 100 thousand dairy cows will be milked in Korea. A reasonable estimate of the prevalence of mastitis today in Korea is approximately 60% of the" cows infected, in an average of two quarters per cow.
The greater part of the mastitis infections was caused by Staphylococci (54.6%), followed by Streptococci (28.5%), Coliform bacteria (4.2%), Corynebacterium spp. (3.4%) and other organisms (9.2%). Coliform-induced mastitis predominated in areas with arable farming, farms where animals are kept permanently indoors, and small to medium sized establishments.
The incidence of mastitis in the national herd in Korea has not altered significantly over the last 10 years, although a variety of intramammary preparations have been available to the veterinary surgeon and to the farmers to combat the disease.
In this paper describes the existing information on the relationship of udder diseases to machine milking methods, diagnosis, ´ and epidemiology of mastitis and outlines a control systems based on managements and the problems of their application on farms.
