I worked in a 650 all-in-one pig barn for 5 years. My husband was never happier!
You can castrate with latex...I've done hundreds! (ok, thousands) Although I would use vinyl now. I prefer the feel. Or even nitrile. They're ok too.

I never had poo de doo. Thankfully. I disinfect that handle with the wipes. I have wipes for my hands in every vehicle to wipe my hands before I put gunk on he leather sterring wheel.

I don't want to have to clean that. SO much easier to just wipe your hands.
I don't use a toilet when I'm away. My body just says no.
