A milk test is a process to evaluate milk production, quality, and overall animal health. It typically involves collecting milk samples from individual animals and analyzing them for various components.
Types of Milk Testing:
DHIA (Dairy Herd Improvement Association) Milk Testing
A structured program where official testers visit the farm, collect milk samples, and record production data.
The test measures milk weight (volume), butterfat, protein, somatic cell count (SCC) (indicator of udder health), and other components.
Results help with herd management, breeding decisions, and production improvement.
One-Day Milk Test
Often used for verifying production in dairy goat performance programs like ADGA’s (American Dairy Goat Association) ST Performance Program.
A licensed tester measures milk production from does over a 24-hour period to verify daily yield.
305-Day or Extended Testing
This type of test tracks a doe’s or cow’s milk production across an entire lactation period, helping determine overall productivity.
Somatic Cell Count (SCC) Testing
Checks for mastitis and udder health issues by measuring white blood cells in the milk.
Butterfat and Protein Testing
Helps determine the quality of milk, which is crucial for cheese and dairy product production.
Why Do a Milk Test?
Helps improve herd genetics by identifying high-producing and high-quality milk animals.
Aids in nutrition and health management by detecting deficiencies or issues.
Provides proof of production for registering performance records (e.g., ADGA, AGS).
Assists in pricing and marketing for those selling milk or dairy products.
Detects mastitis and other health concerns early.
