Noticed a yearling heifer thursday that had a large swelling under her jaw on the right side. Assumed insect stings. Next day, a little more swollen, over into left side, and standing around not eating, some drool.Next day got her crazy butt in the pen and gave a shot of LA200, no signs of any bites, stings, no punctures, etc. The next day the swelling has moved from under her jaw down into her brisket!! and its big (like almost the size of a basketball)-- whats up with that? so i've ruled out insects, its definitely not worms. i'm thinking she got kicked, infection/edema. A similar thing happened to a horse at work but it got a staph infection and it was really gross. Also it could be brisket disease. Any ideas? will this have to be drained? its definitely good that it has moved down into her brisket b/c now she can swallow and breathe ok.
