Question: Why do cows have 4 stomaches

Keywords: , ,

  1. It’s actually quite difficult to digest grass and get anything useful of it. I think this is why cows need four parts to their stomach: they’re for different steps needed to deal with grass.

    Given how complicated it is to digest any food, though, and all the different chemical reactions that have to happen, I think the real question is how human beings can manage with just one stomach!

    Edward is right – grass is pretty hard to digest, so it needs a lot of time in the gastric juices to be of any use to the cow. Actually, its the bacteria in the cow’s stomach that it gets a lot of its nutrients from – and the bacteria break down the grass.

    Each of the four stomachs has a specific function and contains a different population of bacteria and enzymes. The four compartments to the stomach are called the rumen, the reticulum, the omasum, and the abomasum.
