Well on another animal related subject. I just wanted to say that many people at one point in there lives learn that if a cow eats an apple, they can become drunk. People seem to find this to be a funny fact and believe it would be fun to feed cows a lot of apples until they see a drunken cow.
Cows are ruminant animals, these animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Ruminant animals re-digest their food and it goes through a kind of fermenting process.
Cows should not eat apples. It can be fed a treat, but not on a regular bases or a lot of them at once (as entertainment). Apples are very high in starch and create gases after their first stomach and they can't release it. People talk about cows producing methane gas when they fart, but it determines where the gas develops. So a cow can actually die as a result. When a cow can not release gases they get "bloat" and bloat requires a some what surgical process of sticking a long thick needle into their stomach to release the gas. This is all rather painful (´□｀。)
So please before having a little fun with animals, consider there well being and if what you are doing is going to cause pain and suffering. Sorry for the sad note, but it's important information that should become common knowledge.
