Ovarian problems
Ovarian cysts are quite common in goats. They seem more common in "middle-aged" or older does. The doe with ovarian cyst(s) may exhibit "nymphomania," meaning that it seems she is in heat all the time. Or there can just be frequent heats or heats with irregular distances between them, or even masculine behavior. Generally, she will look pretty healthy. This condition can sometimes be treated with hormone injections, which are only available through your veterinarian. Treatment is not always successful. In cattle, the cysts can be manually ruptured, but this may be a whole lot more difficult in goats.
She may have non-functioning ovaries, which will be small. This can be due to low energy feed intake, stress or illness.
Ovarian difficulties can also take the form of too much or too little hormone production which can lead to disturbed cycles, hair loss or constant heat and even reduced growth.
There are also a few cases where the doe will cycle every 42 days, which may indicate problems with one of the ovaries.
Any of these situations usually indicate that you need to discuss the matter with your vet.
Anestrus or irregular cycles
From injuries, endocrine problems or from some disease. In goats, Vitamin E and Vitamin A may help. "
Hope this helps you understand a bit more..
