The antelope we got last year were as good as any deer I have ever eaten. The wife and kids loved the antelope steaks. I wouldn't treat it any different than you do your deer meat. Just be sure to get the hide off and get the meat cooled down ASAP.
Mine was great, shot in September about 1:00 pm, gutted on site, hiked to truck, asked rancher if I could drive across his place to access the edge of the BLM land, drove fifty or so miles to my friends house, skinned and butchered, in the freezer by dark. I took no special care regarding hair oils. That thing was good eating and much better than the deer I shot near Lake Shasta later that fall.
