Genetic Improvement in Dairy Livestock
While Holstein cows dominate commercial milk production due to their high yield, current challenges like heat stress, feed efficiency, and methane emissions require a shift in breeding goals. What alternative breeds or crossbreeding strategies (e.g., with Jersey, Montbéliarde, or indigenous breeds) could make dairy livestock more resilient and sustainable?

Shifting dairy breeding goals away from pure Holstein reliance toward more resilient and sustainable systems requires utilizing breeds with better feed efficiency, heat tolerance, and fertility, often achieved through crossbreeding to leverage heterosis (hybrid vigor).
