Studies show that many cows are infected with incredibly painful infections such as mastitis. Due to over-milking, artificial hormones, bacteria and medications, cowâs udders can become chronically inflamed, thus altering the color and taste of the milk. Over time, this bacterial invasion causes harm to the cowâs mammary gland, reeking havoc on the milk being produced.
