Animal Farms

I was wondering if it wouldn`t be IC like to have a possibility to autofarm animals, first of all something like a baby animal breeder of some kind.
Since Animals grow up automatically there doesn`t have to be a machine for that.

Also a possibility to turn a cow into a mooshroom would be cool.

Furthermore a possibility to extract the spider venom from spiders, the milk from cows and the soup from mooshrooms would be very industrial-like.

It would just be realistic, but you would still have to catch a cow and bring it to the location u want to have it.

Well would it be possible to have something like a spiderfarm that appears as just one block where u can somehow catch a spider in and if u feed that machine than the spider produces poison of some kind, because it sucks to have to kill spiders for weedex.

I think it is quite hard to find a spider spawner?
Or do u mean building a big spawnroom?
Anyway i think of this as cheating.

Ohh i just forgot about those little pests.
Yes your right, but still i find it a bit cheating, i would prefer feeding a encaptured spider and then get its poison just as u would with a snake.
This Idea could work like a machine where u put food in the top slot and u get poison out of the lower slot, of course it would have to be somekind of special food, since there are no flies, i have no Idea what to feed them XD.

Well i`m a one mod kinda person this means my only mod is industrialcraft, i don`t want to put in another mod i would think this kind of farming would be more industrialage stuff like milking cows with a machine, getting poison from spiders without killing them stuff like that.
If it is denied i have no problem with that, but i would like a little tipp.
(Is there a plant that produces some poisonish kinda stuff that u can use to make weedex??)
