Milk Pregnancy Testing
Milk Pregnancy testing has been adopted by many dairy producers as a reliable and convenient means to determine if a cow is pregnant. Using either a preserved milk sample collected on test day, or a strip sample, a milk pregnancy test can be run as early as 28 days post-breeding to determine if the cow is pregnant or not.
Knowing the initial status is only the starting point. Research has shown that 24.7% of pregnancies are lost throughout gestation. (Figure 1 shows the pattern in losses from the initial pregnancy determination until calving) To minimize economic losses, it is key that embryonic losses are caught as early as possible.
Using a confirmatory pregnancy test at two key points in time will help minimize losses. The first occurring around 56 days in gestation where typically 17.2% of losses have occurred and then a second follow-up pre dry-off to catch the remaining 7.2% of losses.
Embryonic losses typically increase due to heat stress. With the summer months ahead, Milk Pregnancy testing can be a convenient tool to help you minimize days open.
