Please don't attempt to lecture me on livestock nutrition. I've been around animals all my life, and I have bred, birthed, fed and slaughtered them. I competed and won at the state level in market and breeding stock competitions, and I also won judging and carcass contests. My wife is a food scientist, and my best friend is an agricultural scientist.
As my wife often says, there are two Laws of Food Science:
1) Fat tastes good
2) Salt makes fat taste better
