Though many people don't consider raising and slaughtering their own animals (it's cruel... I couldn't do that... I'd get attached... etc. etc. etc.), there are some really compelling reasons why you should.
Such as this bit of trickery:
You have limited choices if you're concerned about this kind of practice.
1. Become a vegetarian
2. Find a local farmer and stay away from the industrial stuff
3. Raise your own
I've gone with option three. I tried vegetarianism for about a year. During that time I was sluggish and couldn't stay lean (though we saved plenty of money). Vegetarianism is not for me. And because we're on a tight budget, we're raising as much of our own protein as possible.
If you care about your health and the health of your family, do what you can... unless you simply enjoy the rich velvety goodness of meat glue.
Mmm. Meat glue.
