yesterday and today I have notice the 600 lb holstien limping. He may have got his hoof into a furrow. The pasture is not very smooth. Does it need to be smooth? I noticed in the crease of the front of his hoof looks a little red on his skin, not blood just a little red crease above his hoof. Could this be an infection? Could he have something stuck in the bottom of his hoof? I have lots of burs that the cows are getting in their fur. Can burs cause hoof or skin problems? Also, will a few furrows cause injuries or a broken leg on a cow? Some furrows are 6x6 inches deep.
