Can mares get milk fever?

What is precocious udder?

The precocious udder is udder development in non-pregnant female goats. There are a few different causes for this condition. The most common cause is directly hormonally related, either because of prolonged exposure to progesterone due to the ovary’s inability to release an egg or because we have a case of intersex.

What causes placentitis in mares?
