Aardvark's Better Bovines

This mod refreshes cows, in order to try and bring them up to the standards of modern Minecraft mobs. 

It also adds in some other new things related to cows.

Cows

 Currently, Cows come in two colors - a brown one more similar to a Ayrshire, and a black one a little more like an angus. Neither cows will replace vanilla cow spawns, and by default, both will spawn in.

These cattle act the same as vanilla cows - breed them with wheat, milk them, except that they will attack you if you attack them. Don't grab the bull by the horns!

Zombie Cows can also spawn in. They will give rotten milk, which can cure potion effects - but might leave you sick to your stomach!

Cows will also sometimes drop their skulls upon death. They can be turned into bonemeal, or just left as a cool decoration. 

Finally, you can also craft a new type of block using this mod - the milk bottle.

They are quite handy for when you aren't carrying milk, or don't have the space for it.

By right-clicking a milk bottle, you can drink out of it, and cure any potion effects. You can also take milk out of the bottle using an empty bucket, and refill it using a milk bucket. 

Right now, this is just a smaller little mod idea I've been working on. Let me know what you think, and what additions I should make!
