Dairy cows are vulnerable to mastitis illness, which is an inflammation of the udder glands’ interior tissues brought on by bacterial infections. By using antibiotics like Biomycin-M throughout the dry season, mastitis can be treated. There are frequent physiological changes in the udder at the start and close to the conclusion of the dry season that causes infection. Treatment during the dry season also reduced the 82 percent chance of new infections compared to the period during lactation (30-40 percent).
