This presentation introduces the main mitigation approaches, with attention to their effectiveness, tradeoffs, and relative costs within whole-farm systems. Anaerobic manure storage is the dominant source of methane emissions in manure management systems. Emissions can be reduced through a combination of technological and management strategies, including anaerobic digestion, solids separation, manure acidification, and more frequent […]

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 […]

It is getting hotter and hotter here in Fond du Lac County and cows feel it too. For that reason, we are talking about ventilation in dairies. 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 […]

Bovi-Noticias is a bilingual newsletter (English and Spanish) created to support dairy producers and farm managers in training, educating, and engaging their teams. Its mission is to improve on-farm practices, boost worker confidence and skills, and promote safer workplace behaviors.  Bovi-Noticias is more than a newsletter—it’s a bridge between knowledge and action on the farm.  It delivers relevant, easy-to-understand information tailored to both dairy workers and […]

Commercially launched over a decade ago, high-oleic soybeans (HOSB) have continued to spark interest as a beneficial ingredient for dairy rations. As feeding research trials continue to emerge, we’re gaining better insights into how HOSB can fit within dairy diets compared to conventional soybeans. This article discusses what makes high-oleic soybeans unique, summarizes findings from […]
