Cows are passive mobs and have 10 hearts. They have two drops which are Leather and Beef. If they are on fire when killed, they will drop steak instead. If you tap on a cow while holding a Bucket, the bucket will be filled with Milk. In a future update Milk could possibly be used to remove potion effects.
History
Cows were first added to MCPE in 0.3.0.
Cows started dropping leather in 0.6.0, therefore making it possible to craft Leather Armor. File:Steak.png
