here are some tips for drawing out infections. Epsom salts mix w/ water and use as a spray or bandage up drenched in epsom salts.
you know the plant the hosta? Well there is a wild one out there called... it's on the tip of my brain, any how it can help to draw out infection. squish the leaves so that some of the juice flows and then wrap on the wound.
SCRAP the vet wrap. It seals the wound so it can not dry out increasing the infection. Creates a nice warm wet enviroment for bacteria to grow.
My advice and this comes from experience in bull feet problems that do not want to heal.
Get the bull ready for slaughter or such. Withdrawl times followed. With an absess now he will not be a great preformer in the future. We have been down that road twice. Treated when it was treatable and for some reason it would not go away. We had the vet work on him serval times. on the tipping table to clean his feet, and the drugs. We ended up spending near half the cost of him to get him better. And he did. Next breeding season he was ready to go ...vet aproved and all. We got 5" of rain and he went down just days before turnout. Tried to treat and did not work. With that vet call and the drugs and with the previous years vet bills and his down time, extra hay and grain we could have bought a new one.
Next advice look into insurance for bulls. Life, loss of use, and loss of function. This year it will hopefully pay off. One bull (another) went down with foot rot and lump on the jaw (last year fractured jaw, vet treated and it healed, passed a vet pre breeding test this year). We are putting a loss of use to cover a bull rental. If he does not heal the life policy will hope fully kick in. First year doing this so...
When a bull goes down it is hard cause they are so expensive. If an insurance policy can help with the finances all the better.
For 4 bulls it cost $800.00 for $8500.00 in bulls.
It gives us $1000.00 for rental on each bull insured, and payout of purchase price less amount recieved from slaughter on each bull. No deductable, and does not affect your main insurance policy if you make a claim. You have to buy the policy within 48 hours of a breeding soundness evaluation.
Hope he gets better
