I am curious Ron if this growth is mostly muscle or is mostly fat . . . .or a good combo of both. We live in a country where the goerment is pushing for low fat diets but I cannot lose weight or maintain my weight on a low fat diet. As hard as it is to beleive, the high % fat in my diet but still under about 2000 calories, I loose weight. So fat sources that are clean fat are very important to me.
( Besides, IMO the government info is based on commerically produced animal fats and meats which are remarkably different than home grown depending on the feedstuffs.All the more reason to produce our own food. )
When I did this with the bresse, it was both fat and muscle. I use organic Kamut grain. It is an ancient Wheat and is high in protein:
