A generation or two ago, it was common knowledge that, if you fed cattle, your pigs and chickens would eat for free.

(Not being sarcastic) Due to the waste food from the cattle? I'm not familiar with this, never having spent much time on a farm.

Corn isn't all that efficiently digested. Although feedlot rations now are pretty efficient, in the good old days a steer's foraging on pasture would be supplemented by a bucket of shelled or ear corn thrown in the trough. Pigs would then "follow" the steers in the same feedlot and chickens would clean up after everybody.

Eggs from hens fed on such a diet made incredible noodles.
