why do humans need to eat many different kind of foods to get their vitamins etc but large animals like cows only need grass to survive?
In: Biology
Because their digestive system is centered around their natural diet. People would naturally eat all different kinds of things, but cows would only normally eat grass. I’m a horse owner, and sometimes I find that my horses will be eating dirt. This is because they can tell they have mineral deficiency so they take it into their own hands and eat dirt to get those minerals. It’s always a certain time of the year when my horses are coming in from pasture with muddy mouths, so then I’ll go buy a mineral block for them to lick or I’ll buy them some loose minerals to sprinkle in their feed. I like to leave blocks, because then they can decide when they need it and when they don’t because too much mineral could cause issues and it’s more natural for them that way. I’ve seen people with cows leave troughs of loose mineral in the pastures and the cows take a few mouthfuls when they feel like they need it. Digestive systems in large animals are so so different from those of humans
