Mastitus
Summer heat and humidity can create the ideal environment for mastitis-causing pathogens to grow. In addition, intense heat can cause the cow to become stressed which results in lowering the immune system function. These two factors together create the perfect storm for mastitis to take a toll on the herd.
Bovine mastitis is the most costly disease for dairy producers. Mastitis is an inflammation of the mammary gland that is usually caused by bacteria that enter the gland through the teat end.
