until about 3 weeks ago we would process everthing as soon as they came off of the truck branding banding horns and give them a shot of pinacillin and then watch them close of the even look like they are getting somthing they would get treated. Now we have been useing a past called Cellarator turbo on arival and have been verry happy with the results works great. Alot of it has to do with how they are handeled they are hauled in by our trucks and worked as soon as they get off to reduce stress they are started on grain with buckets walking through them and keeping them calm will get them to start eating faster. But like I said the real trick to making money in this type of operation is knowing the market.
