Most dairy producers have probably heard that in vitro fertilization (IVF) is expensive but may not know much more about it than that.

It’s true, IVF can be expensive, but so is feed and labor.

Cow with calvesIn vitro fertilization (IVF) is finding its place on commercial dairies, but the way it is being used may come as a surprise.

IVF technology is not new to the dairy industry. For years, it has been used to increase the number of offspring from genetically elite females. These were often hand-picked, high-type show cows or off-the-charts genomic animals. IVF opened a window of opportunity to harvest oocytes and, ultimately, make more embryos from these top-tier cattle.

Dairy employeesWhat if you could improve your dairy’s 21-day pregnancy rate simply by taking the time to hold a bi-monthly team meeting? That is what happened to nearly all of the 40 dairies enrolled in the University of Wisconsin’s Repro Money program.

Back in November, the Council on Dairy Cattle Breeding (CDCB) began conducting preliminary genomic evaluations on a weekly basis. Prior to this change, genomic evaluations were provided each month, requiring producers to submit samples by a predetermined due date in order to deliver results as part of the next month’s official report.

While certainly not a new concept, inbreeding has become a hot topic in recent years. Producer concern is on the rise over whether genomics is creating too much inbreeding in the dairy cattle population. The worry is that there will soon be limited options to which a herd can be bred to avoid negative effects of inbreeding.

Today, many dairy producers are integrating genomic testing into their daily breeding and selection decisions or contemplating doing so. It is remarkable to think that a tissue sample collected from the ear, a hair pulled from the tail switch or a drop of blood spotted onto a card from a day-old calf can get you a genetic evaluation equal to progeny tests on many daughters of sires.
