I think you misunderstand the article. THese are not way out of date. IF anything this kind of thinking is gaining ground. Our commercial food animals are fed less than desireale feeds and are at best sources of protein but no longer have the higher levels ofVItA etc. I myself am not interested in eating Beef derived of newspapers. ( Mother Earth) Having grown lamb for over 20 years I ws not surprised to find that lamb is considered one of the better choices on the market as they rarely are fed in a feed lot but go right to slaughter off the fields.
Every day I see my chickens choose grass over eating pellets. Mine free range. THey eat bugs, worms, flies and all manner of extras. Pellets are their last choice.
I 'm sorry you don't have the best grwoing conditions. You can supplement your chickens feed with greens of many types. SInce you buy all their feed,consider adding aflfalfa pellets to up the beneficial greens in their diet. In the summer mine get leftovers from the garden and our kitchen. Friends often save their leftovers too for my birds. You can grow green fodder as some call it ( ie. sprouted oats.)
Poor quality food has led to a meriad of health issues in us humans. Only in the last 50 years or so have we moved to feed lot style production and moved the animals off the fields.
If you are interested , check out Sugar Mtn Farm in VT. Hogs are raised on pasture with some supplements, but primarily eat high quality forages and the piglets supplemented with chicken eggs for more protein. Here is a case where Vt govenment supports agricultural endevors more than many other states.
Good point. One question. Beef is raised for 6-7 mo on pasture before going to the feed lots. How long do they have to stay before slaughter. Just wondering. I've read that to finish chickens to put in a small pen and feed them good for 2 wks. How about the beef.
