I don't anything about this but I did find this forum post (see below) ... hope that helps!

Hello Mr. Kirsten, I will suggest you to take your goat daily walks on hard & Loose surface, It will help strengthen the muscles around the pasterns. You should make some changes in her feed. Your goat need less protein- heavy diet with extra supplements. Consult a veterinarian to ensure your goat is getting the nutrients she needs.
