Torn ears on hogs

when we used to have our catchdog competitions we would have them once a month and the sunday afterwards we would catch all the hogs and doctor them...we would put diesel and turpentine in a pump sprayer and spray them down good and put furazone on them and juice them up with sum antibiotics turn them back loose in the holding pen and would just have a pole drove in the ground or a tree and nail old carpet or burlap to them and soak them in burnt motor oil and let them rub it down...i mean we had close to 75 hogs in that pen so we had to always keep replacing he oil...we just went to a mechanic shop and dropped off a few five gallon buckets with lids and gave him like 5 dollars abucket and he was more than willing to fill up the buckets up and get rid of the oil...hope this helps yall out
