It does not apply to red meat generally. The larger an animal is the higher a percentage of fat it contains. A blue whale has 35% body fat, a cow is roughly 25% body fat, and a squirrel/rabbit is roughly 5% body fat. Also, I render my own tallow from beef suet and often add it to ground beef. I also slow-cook roasts in tallow.
