First lets start with the goat
I have a cure for those hairy stray teats that like to divert the milk stream to your pants.
Now to the goat kit. It's a simple tool box that I can bring inside during the winter so it don't freeze. I start with a clean rag and a spray bottle of soapy water and give her a good scrub. Then I pull a couple of unscented wet wipes and put a good amount of Purell on it and give a second scrubbing concentrating on the teats. This is also good to help sterilize your hands. Next is a "strip" bucket I leave out to get a good 4 to 5 first squeezes to get that first "dirty" stream out.
We put 2 frozen Avian water bottles in the bucket. The goats milk comes out sterile and its how you handle it keeps it sterile. The colder you can get it the fastest is the best and you can put those water bottles in the dish washer after you strain the milk.
I also went to Home Depot and bought that steal looking non rusting screen that I cut and form fitted to the top of the bucket to catch any hairs or bugs that may try to get in there. (dishwasher safe also) I top the bucket off with a heavy dinner plate when I set the milk bucket aside. When I'm done milking, the bucket goes straight in the freezer while the goats finish their meal at the stanchions. I take the milk out and put it in the fridge just before it starts to freeze.
After milking you want to sterilize the teats as the last step. Some people use Fight Bac in a can but I been using Purell for years.
When kidding season comes, be sure to shave that belly, udder, bum, and tail or you will have a long time sticky mess.
