Benefits of milk pregnancy testing
A convenient way to find out which cows are pregnant using milk samples from a herd test.
Milk pregnancy testing is:
- non-invasive — no need for rectal scanning
- convenient — you can combine it with a routine herd test
- accurate — the results compare very favourably with vet pregnancy diagnosis.
How milk pregnancy testing works
We use milk samples from a routine herd test to detect pregnancy-associated proteins called glycoproteins. These proteins are produced by the placenta and can be detected 28 days after conception.
Two options available
- Whole herd — test all your animals.
- Partial herd — test a selected group of animals (minimum 25).
You’ll get the results by email up to a week after you get the lab strip from your herd-test. They’re also automatically updated to MINDA.
There are three possible results:
- No pregnancy detected.
- Re-check — when we can’t confirm whether a cow is pregnant or not.
Ask your vet to diagnose animals in the re-check category.
False positive results are possible in animals that have recently aborted. This is because it takes at least two weeks for pregnancy protein levels to drop.
When to test
Book a milk pregnancy test at least 28 days after your herd’s final mating. You must tell us your final mating date (including natural mating bulls) when you book the test.
