With fertility rates on the rise and data guiding every decision, beef-on-dairy matings – especially with composite sires – are helping dairies optimize both efficiency and profitability.

Voluntary waiting periods (VWP) can vary based on the type of operation, management style, herd size and more. Sometimes, VWP can be based on the individuality of each animal. At Isaac Dairy in Steinbach, Manitoba, this strategy aids in overall profitability, creates more space in the dry cow pen, helps select replacement animals and contributes to a sustainable operation.

Dairy producers face many challenges. Animal health, nutrition, milk markets and personnel management cause many farmers to lose sleep. Maintenance and management of a semen tank is a factor that every dairy producer can control.

As cattle producers explore avenues for boosting productivity, the spotlight often shines on genetics. For crossbred beef-on-dairy calves, maximizing genetic potential goes beyond selecting the right genes – it is also about creating the right environment to allow those genes to fully express.

Which traits make an efficient dairy cow? To answer that question, it is useful to carefully think about what a very efficient dairy cow looks like. One definition of an efficient dairy cow is cow that maximizes milk production while maintaining good health and fertility, thereby optimizing profitability for the producer.

“Today we have a third of the number of cows we had in 1960, and we’re producing more milk,” said Christine Baes of the University of Guelph during her keynote presentation at the 2024 Dairy Cattle Reproduction Council annual meeting. “That’s a pretty good sustainability story, but when you Google ‘sustainability and dairy cows,’ you see headlines about cow flatulence. Why is that?”
