It is a form of ecoli mastitis, that can be deadly to the calf and cow. I have used large doses of oxytet for the cow, then stripped the udder daily, and infused a RX mastitis treatment daily for a week. It was awful, the milk was the color of rasberries, full of clots and strings. I didn't stop until the milk turned back to milk. I tubed the calf formula for two weeks. The calf almost died. He scoured, got navel ill, joint ill, pneumonia (see the post topic "Mysterious Mo"). That calf was sick for about 4 months. I never had worked so hard to keep an animal alive. Believe it, or not, he is fine, now. He nurses off his mother, but I don't think she produces as much milk as a normal cow, as Mo is not as heavy as his peers. They are both healthy now and are going to slaughter, but I thought I was going to lose the pair.
