SOME STUDIES ON MASTITIS IN CATTLE

Abstract

Mastitis is an inflammatory change of the mammary gland which along with physical, chemical and microbiological changes, is characterized by an increase in the somatic cell count especially leukocytes in the milk and by pathological changes in the mammary tissue (Tolle, 1971). Mastitis is a major disease problem which appears to be world wide in distribution and affects all species of farm animals. It attains its major significance in terms of the profound impact on the value and productive efficiency of milk producing animals (Hafez et aL, 1987).
