Ok I have been up for a while studying for a test,so now I am having a total brain fart on names of things. LOL. ??? But I had a heifer get infected after surgical dehorning way back when I first started showing. Hers actually got kinda bad because we were gone for a couple days and my granddad was feeding, when we came back and realized she was infected on both sides it was so bad that she ended up blowing all the stitches. What the vet had us use, was go get some of the tubes of antibiotich that you use for mastitis(it will be in a tube similar to a paste deworming tube, but the end will be made to insert into the teat of a cow with mastitis). I would actually use like an iodine or betadine surgical or wound scrub to squirt in to clean, peroxide is great for cleaning surface wounds, but can actually cause added inflamation and you dont want that inside an area that is sutured. After flushing, squirt some of the mastitis antibiotic in where the stitch has blown. If it does swell and the incision gapes, get you some silver sulfadiozene cream and put in the opening after the antibiotich. Do this twice a day, and you are golden. The heifer that we had ended up blowing all the sutures on both sides, big swollen, gaping holes in her head, we did this twice a day for about 2-3 weeks and you couldnt tell she had ever had an incesion, healed over perfectly, no scar line, she looked naturally polled.
