A Mastitis Indicator is a device used for detecting mastitis and stops it from spreading further in cows. The device is specifically tailored to identify subclinical inflammation in the udders of cows before visible symptoms manifest. By utilizing advanced technology this device helps in tracking and maintaining the health condition of the cows and prevents the progression of the disease. The clear plastic tube is attached to the milking machine, as the milk flows through the tube any clots or abnormalities will be visible, indicating a potential case of mastitis. This is a very valuable device for a dairy farm as it helps in detection and prevention of mastitis and prevents the contamination of milk.
