Timely ingestion of high-quality colostrum transfers critical immunoglobulins to newborn calves, protecting them during the early immune development phase. Absorption efficiency rapidly declines after four hours of life, with all absorption ending by 24 hours. High bacterial contamination in equipment or udders blocks immunoglobulin uptake and introduces infectious agents to the calf. Establishing strict colostrum […]
We know that every farm operation has a list of “someday” tasks. Often, organizing essential documents and financial records sits right at the top of that list. Whether preparing for an emergency or long-term transition planning, having your vital records in order is one of the best gifts you can give your family and your […]
The University of Wisconsin-Madison Division of Extension is inviting farm families and farm business owners to participate in Cultivating Your Farm’s Future, an interactive virtual program designed to kickstart the vital process of farm succession planning. Succession planning is more than just paperwork; it is about answering the critical questions that define a farm’s survival […]

El “Break” Info-Lechero, the Spanish webinar for Wisconsin’s Dairy workers and farmers is back for the 4th year! To help Wisconsin dairy workers and the dairy community to get the most current and update research information, UW Madison-Extension has developed the Dairy Spanish Webinar El “Break” Info-Lechero 2026. This Webinar is an update on different […]
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 […]
