In this presentation, Dr. Kent Weigel discusses genomic selection for feed efficiency in dairy cows.

The goal of the project is to increase the efficiency and sustainability of producing milk including 5 specific aims:

1. Develop a dairy feed efficiency database seeded with genotype and phenotype data for 8000 Holstein cows.
2. Determine the genetic architecture of feed efficiency and build a foundation for genomic selection of more efficient animals.
3. Develop and implement genomic breeding tools to produce cows with enhanced feed efficiency.
4. Develop and implement practical decision support tools to improve whole herd feed efficiency.
5. Educate future leaders, voters, and consumers about key practices in dairy husbandry that promote feed efficiency and environmental sustainability.
