What's in your Cattle first aid kit?

After reading through a good thread started by Ann here: https://permies.com/t/43673/critter-care/livestock-aid-kit i though it would be a good idea to start a cow specific first aid thread.

What types of things would you keep on hand for cattle first aid.
i guess the kits would vary whether you have beef or dairy cattle, so its probably best to separate into 2 groups, although i know some items would cross over.


i would like suggestions to be as natural as possible - but keeping in mind you don't want to lose a $2000 cow because you don't have a $10 tube of [unnatural] calcium.

Dairy:
calcium (for milk fever)
blood stop
something to solve a major bloat problem (forget the product name. a knife in extreme cases )
gauze
iodine
duct tape
calf pulling chains
plastic gloves (shoulder length and regular)


Beef: (i personally dont have much experience here)
blood stop
something to solve a major bloat problem
gauze
iodine
duct tape
plastic gloves

please quote and add/correct these lists.

thanks in advance.
