I have had big old boars stink up the kitchen. Big sows not so. I just butchered a 320 pound sow we shot on a disease sampling mission. Had her skinned and hanging in the cooler 30 minutes after she saw the light(literally). Big hogs are superiorally insulated due to the thick fat. It is important to cool them asap. Back when I ran dogs, I would trade the big boars to the locals for gas, and keep the sows and small boars for myself. Seems as if Colt 45 and Old English 800 has the tendency to negate any bad taste. Just my hypothesis.
