The financial incentive for this genetic pivot is significant for the dairy producer. Farms are now strategically using sexed semen to divide their operations: the top 60% of the herd, defined by genetic potential, is bred with dairy female sexed semen for replacements. Crucially, the bottom 40% of the herd is crossed with male sexed semen from high-value beef bulls. This dual-purpose strategy delivers maximum genetic improvement for future milking stock while generating revenue from premium beef-cross calves selling for over $2,000—three times the value of a pure dairy bull calf.

This strategy is amplified by the power of genomics. The use of genomic sequencing, which allows for genetic potential analysis at birth, accelerates genetic improvement by four years compared to the decades-old progeny testing methods. This results in a staggering 3% annual efficiency increase in the herd, as tracked by Lactanet data. The combined result is clear: Canada now produces 23% more milk than a decade ago with 19,000 fewer cattle, proving that maximizing milk production efficiency is the new economic imperative.

However, the reduction in cow numbers and fewer necessary calvings have translated directly into a structural beef supply shortage. Dairy farms historically provided up to 20% of the raw material for the Canadian beef sector through culled cows and male calves. This supply shrinkage, combined with the 11% decline in pure beef cattle numbers across the US and Canada due to ongoing climate change and drought, has broken the traditional three-year livestock supply cycle and propelled ground beef prices to record highs.
