Extension Fond du Lac County

UW–Madison Extension Educators invite you to participate in a short survey. We are conducting research to better understand what dairy and livestock producers currently know about biosecurity, as well as how and what they would like to learn moving forward. The survey will take approximately 15 minutes to complete. Your responses will remain anonymous, and […]

Dairy ventilation systems require optimized fan selection and design efficiency to combat severe heat stress and minimize hidden costs. Proper mechanical ventilation controls airflow, removes heat and moisture, […]

Dietary lipids provide high-density energy to dairy cows, primarily boosting milk production and reproductive performance. Microbes in the rumen tend to turn unsaturated fatty acids into saturated fatty acids through a process called biohydrogenation. Later, the fatty acids go to the small intestine for absorption. Managing this fat intake within specific thresholds prevents negative rumen […]
