The protein feed has increased the weights of our bucks dramatically. I wish the racks would have had the same results, lol. A 5.5 or 6.5 year old buck will weigh between 185-210 lbs before the rut now. Prior to the feed it was about 150-175 lbs. Last year we took our heaviest buck. It was a mature 6 point and he weighed in at 212 lbs. Once the rut starts the weights start to drop rapidly. I have a tight buck to doe ratio so these boys have to work pretty hard to have a little fun.
There are some parts of Texas where a mature buck is lucky to weigh 125 lbs at maturity.
