Not exactly sure what is going on with one of my goats. When pouring the milk out of the pasturizer, there is a thick, almost mucus-like, white residue at the bottom of the pasturizer. I am pretty sure I know which goat it is. She had mastitis earlier this year and her left teat never recovered. I'm thinking it is maybe her. Any thoughts of what I should be doing? Possibly retreat her? Thanks!
