Dairy goats should be purchased from Registered studs.
A list of these studs will be available from the Secretary of the branch in your state .
When buying a doe in milk, it is wise to buy one not more than 4 years old as this leaves about half the animal’s productive life in front of it. To assess its milking ability, see it milked right out in the evening and then be present to see it milked out the following morning.
After the udder is milked out, examine it for lumps and thickenings which could indicate some udder problem. The udder should be shrunken silky and soft, and the skin free of sores or warts. The teats should also be free of warts, sores and thickenings especially around the orifice area. Teats of medium length, which are easy to milk with a good milk flow, are preferred.
You should also open the mouth to examine the teeth and ensure there are 8 sound biting teeth on the lower jaw.
The general health and appearance of the doe should be good, and if she has been in milk for more than seven months she should again be in kid. It is important that a goat can be easily caught and has a docile temperament.
An alternative way of getting started with Dairy Goats is to buy, preferably two young female kids (remember they are a herd animal and like company) and rear these yourself. It is usual not to mate young goats in their first year until they are about 19 months of age so that they kid and come into production at approximately 2 years of age. It always pays to buy a good quality animal from reliable milking stock.
Remember to get the transfer of registration done and a service certificate if the doe is in kid at the time of purchase along with a receipt for payment.. Also check her health papers.
