They start out living life in green pastures. Then, at a young age they are loaded up in cattle trailers or semi-trucks. Most of them make long treks, 20 hours, with no food, water or rest. That's how a cow starts it's journey to it's new home in a feedlot. Stressful? Yes. Unfortunately, the stress is just beginning for those cows.
Stinky, crowded, filthy, inhuman etc. are all words that accurately describe a feedlot. These living conditions are actually quite stressful for the cattle. Stress on a cow may sound funny, but it's a real and dangerous thing. Cattle that are stressed are more susceptible to illness and diseases. Not to mention, stressed out cattle produce tough and tasteless beef. Is your beef coming from stressed out feedlot cows?
