Over the past few years, on farm breeding strategies have shifted to include the use of beef sire semen to breed lower genetic merit females and increase the sale value of calves. In...
One thing I love about the dairy industry is that we are always looking for ways to improve on what we are already doing…
And the McCartys are no different.
In this episode of the Uplevel Dairy Podcast, we are heading...
What is A2 Milk?
A2 milk comes from cows that produce only the A2 variant of beta-casein protein, which makes up 30% of milk protein. This milk may be easier for humans to digest, but scientific evidence supporting health...

The Council for Dairy Cattle Breeding (CDCB) releases updated dairy sire summaries three times a year to help producers make informed decisions about herd genetics. Advances in genomic data and expanded trait evaluations have made it easier to identify...
In light of rising feed costs, dairy farms can boost profitability by focusing on whole-farm feed efficiency, particularly by managing feed cost per hundredweight (cwt) of energy-corrected milk. According to data from the University of Minnesota, the top 10%...
DNA parentage testing in animals operates on exclusion principles, where an offspring’s DNA profile is compared to that of potential parents. If the genetic markers don’t align, the parent is excluded. When markers match across the evaluated DNA markers,...
A University of Wisconsin–Madison team conducted surveys in 2019 and 2023, examining how dairy farms integrate beef x dairy crossbreeding to improve market efficiency. The surveys revealed that conception rate, calving ease, and semen cost were the top criteria...
