The study will focus on cattle’s mitochondria, cell components whose biochemical activity produces most of the body’s energy for cell function. The researchers hope the project will expand the range of genetic tools used by animal breeders.

The number of straws of beef semen sold to the dairy industry has more than doubled in the last five years, although dairy cow numbers have been relatively stagnant. So what has changed?

While choosing replacement females may seem like a singular task, you know that months and years of strategic planning lead up to the moment. Every replacement heifer is evidence of the work that’s been done and is the foundation of future herd performance and profitability.

Larger cows and their calves’ heavier weaning weights may not bring profits to the operation. How do these cattle impact productivity, and what changes can beef producers make to improve profitability?

“Male sexed semen is an opportunity to capture value,” said Kansas State University's Ken Odde, who also helps manage a family cow-calf ranch in South Dakota. “The opportunity’s greater when the price spread between steers and heifers is significant.”

Over the past few years, genetic testing has become more readily available and used by commercial cattlemen. Information that was once used mainly by registered cattle producers is being utilized to make improvements on commercial operations and produce higher-performing cattle by making decisions with more information.

To remain competitive in today’s beef industry, commercial producers must identify and implement technologies that have favorable impacts on their beef cattle enterprises, and crossbreeding is one such technology.

In recent years, the dairy industry has witnessed a significant rise in the number of beef cross calves being born. This emerging trend of crossbreeding dairy cows with beef bulls at a large scale has not been a linear process.

The usual suspects (expected progeny differences [EPDs], genomic testing, heterosis) were covered, as were some issues (beef-on-dairy, methane emissions, cardiac health) that may have been a bit more of a surprise to the uninitiated at an event ostensibly dedicated to beef cattle genetics.
