In today’s world, human activities increasingly threaten our planet and natural resources, creating a pressing need for solutions that either reduce environmental impacts or improve production efficiency. Food systems, particularly beef production, contribute significantly to climate change, and are often criticized for their high environmental footprint. However, eliminating beef entirely is not a viable option, as much of Europe’s grassland would go unused, and a key protein source would be lost. A more sustainable approach is the dairy-beef system, which utilizes surplus dairy animals for meat production. This approach requires fewer resources and generates lower greenhouse gas emissions than conventional beef breeds.
By examining the genetic parameters of cow carcass traits and their genetic correlations with key traits in the Nordic breeding goal (Nordic Total Merit index), this research aims to improve carcass traits of dairy cows without compromising efficiency, milk yield or health. We will also evaluate the marginal economic values of each trait to assess the financial impact of including carcass traits in breeding goals. Finally, simulation studies will be conducted to explore the long-term genetic and economic impacts of incorporating cow carcass traits into dairy breeding program. The results will provide practical insights for farmers and industry, showing how the dairy-beef system can deliver high-quality beef while enhancing profitability and environmental sustainability.
