The One-Day Milk Test
Maxine Kinne

Monthly Dairy Herd Improvement (DHI) testing can be prohibitively expensive, depending on where you live and how many goats you are milking. A group or an individual may sponsor a one-day test. An official testing representative must conduct the proceedings.

Does must be milked out completely 12 hours before the first test. Then, two separate milkings 12 hours apart are observed and sampled. The testing agent then sends the samples to an accredited milk testing laboratory. Milk samples are tested for butterfat content and solid non-fat proteins, but some other tests may also be requested, like somatic cell count. When the lab results are issued, a simple milk production formula is used to project each doe's milking ability for that lactation.

Points are earned on the basis of milk quantity, days in milk and butterfat. Each pound of milk is awarded one point, figured to one decimal place. Each 0.05 pound of butterfat earns one point. And for each complete 10 days the doe has been in milk, she earns 0.1 point up to a maximum of 3.6 points. Eighteen points are needed to earn a production award.
