A problem that occurs with new milking does often is cracked teats!
Any ladies who have breastfed will likely sympathise with this issue. It is painful, can turn into a infection and can make the doe not want to feed kids or be milked.
I've been using White Ointment on Poppy teat (only one was effected) and we have finally healed the crack. Now we need to soften the skin again, as the kids don't want to feed on that teat! So we are going to use coconut oil tomorrow, several times a day. We'll up date how we go.
