▶ Watch: Grazing your way to reduced heifer cost and better sustainability
Back to our roots with grazing dairy heifers with Jason Cavadini, Extension Grazing Outreach Specialist
Just a few generations ago nearly all dairy heifers spent part of the year on pasture. Today, most dairy farmers choose not to implement grazing. But there’s good reason for dairy farms to consider going Back to Our Roots with grazing of dairy heifers. It’s important to understand the distinctions between managed grazing and other types of grazing management. The three foundational principles – the Three R’s – are what make managed grazing different. This presentation will discuss how Rotation, Rest, and Residual influence forage production, animal performance, and cost savings for heifer raising programs.
Advancing sustainable grazing: quantification of greenhouse gas emissions from pastures using a “flying” air analyzer with Nesli Akdeniz, Livestock Controlled Environments Extension Specialist
The Rotational Grazing Handbook (A3529) recommends that all pastures with less than 40% legume content require N fertilization for optimal growth. Fertilizer application not only contributes to additional forage growth, allowing for a longer grazing period but also enhances pasture yields leading to increased carbon sequestration. However, nitrogen fertilizer should be applied in a way that minimizes the emissions of greenhouse gases and their precursors. In this presentation, we will discuss the quantification of greenhouse gas emissions from dairy pastures using a “flying” air analyzer. We will also explore the effects of split N application and drought conditions on these emissions.

Heat Stress in Calves
▶ Watch: Understanding the carryover effects of early life heat stress on dairy calves
In this episode of Badger Dairy Insight, we hear from Dr. Jimena Laporta, Assistant Professor – Lactation Physiology for the University of Wisconsin-Madison Department of Animal and Dairy Sciences.
Heat stress, a prevalent challenge in modern dairy farming, has been shown to have far-reaching consequences on young calves’ health, well-being, and productivity; even before they are born. This presentation will explore how heat stress affects the physiological, behavioral, and developmental aspects of calves during their critical early stages of life and highlight the long-lasting implications that persist into adulthood. Additionally, this presentation will discuss potential strategies to alleviate the detrimental impacts of heat stress on dairy calves, including housing management interventions.
▶ Watch: Strategies for keeping calves cool in hutches
In this brief presentation, Jennifer Van Os will continue some of the themes from Dr. Laporta’s presentation, specifically discussing collaborative work at UW-Madison to identify practical strategies for alleviating heat stress in hutch-housed dairy calves.

▶ Watch: Updating our thinking about corn silage and alternative forages
MILK 2024 – what’s new?
Differences in nutrient composition and digestibility among corn hybrids have the potential to impact energy content of corn silage and ultimately influence dairy cow production. From the perspective of maximizing nutritive value, energy predictions of corn silage can be useful to aid producers in selecting hybrids. The MILK index was developed to predict the energy content (milk/ton) and energy yield (milk/acre) of forages. This presentation will discuss the novel aspects of the newest iteration of the MILK model.
Cover crops, alternative crops- how well do they feed?
Extension gathered samples of forages at harvest and after fermentation and visited with producers about their experiences with some of the forages that today are being used in addition to corn silage and alfalfa. These feeds included winter cereals such as rye and triticale, warm season grasses such as sorghum-sudangrass and annuals including Italian ryegrass and mixtures with legumes. These crops fill many agronomic and conservation niches, but how well can they be utilized to feed lactating dairy cows. Results are variable but many opportunities exist.
July – August 2024 Topics
July 16, 2024
▶ Watch: Leveraging digital technologies to improve management decisions in dairy farms
Dr. João Dórea is an assistant professor in Precision Agriculture and Data Analytics in the Department of Animal and Dairy Sciences at UW–Madison. Dr. Dorea develops research focused on digital technology and predictive analytics to optimize farm management decisions. Dr. Dórea’s research group is interested in large-scale implementation of computer vision systems, wearable sensors, infrared spectroscopy, and other sensors to monitor animals in livestock farms. Examples of application include the use of digital technologies to monitor animal behavior, growth development, social interaction, and early detection of diseases or animal welfare concerns.

▶ Watch: New Concepts in Colostrum Feeding for Dairy Calves
Dairy producers should consider feeding a smaller volume of colostrum to newborn calves. Delivering the correct mass of immunoglobulin in a smaller volume ensures the successful transfer of passive immunity (TPI) is preferable to current colostrum feeding guidelines. Feeding too large a volume of colostrum can cause serious complications that affect the health and well-being of newborn calves.

Fresh cows: fetching the cow and blood money
Ryan Pralle, Assistant Professor in the School of Agriculture at the University of Wisconsin-Platteville will talk about two projects he is currently working on. The first topic will be on a novel blood panel developed that will predict high liver triglyceride status in multiparous cows as a proxy for fatty liver. His second topic will be on the impact of early lactation milking frequency (3x vs 6x) on multiparous dairy cow production and health from cows at the UW-Platteville farm utilizing Lely robotic milkers. He will discuss the differences in productivity, possibly nutrient partitioning, and surprising lack of habituation/training on the high frequency cows to high voluntary visits after they stopped fetching intensively.

Manure Processing Systems
Rebecca Larson, Professor and Extension Specialist in the Nelson Institute for Environmental Studies at the University of Wisconsin-Madison will talk about manure processing systems. The information will cover a wide variety of research trials and extension information on the types of manure processing systems available including their benefits and limitations. She will cover composting, anaerobic digestion, solid liquid separation, sand separation, struvite recovery, pelleting/granulation, drying, pyrolysis (biochar), membrane treatment, and treatment to clean water. The presentation will include the basic system components, current status of the technology, future direction of the technology, products and nutrient values they each produce, and general limitations and operating requirements.

Moving cows without the cows: new options for interactive employee training
Handling cows is necessary to harvest milk and provide animal care, but these interactions also present a risk of injury to personnel. Inappropriate cow handling threatens animal welfare, milk production, and public trust in dairy farming. But how can the industry best teach these skills? Interactive learning experiences can help build confidence by allowing dairy workers to actively participate in their own training.
Interactive training methods, such as group activities, simulations, games or other hands-on methods, keep employees engaged in the learning process and create a safe space for questions. In collaboration with Wisconsin dairy stakeholders, Extension Dairy Welfare Specialist & UW Madison Department of Animal & Dairy Science Assistant Professor, Jennifer Van Os, created an innovative learning tool for people to practice the appropriate handling of dairy cows.
Join Jennifer Van Os and Extension Farm Management Specialist Jim Versweyveld as they discuss interactive learning and the Mooving Cows(TM) digital educational game in which learners practice moving cows in simulated dairy farm environments. The game, like a flight simulator, is a way for participants to “learn by doing.” The learning objectives in the game are to understand how human actions affect cow behavior, stress, productivity, and worker safety.
