Typically you will get more bang for your buck with a domestic, ergo the average daily gain will be better with a domestic when compared to a piney wood rooter. The domestic is genetcally superior towards muscling, where as the rooter is geared for survival, and doesn't muscle out as much as the domestics. There are, however times when a rooter crossbreeds with a domestic and the offspring will muscle out heavier, but usually not the case(a crap shoot). As mentioned above, castration is necessary. As far as flavor, both will eat fine. The rooter will "sweeten up" with the feed. I'd weigh all the costs, are the feral hogs free?
