Real Science Exchange-Dairy

Greg Nye introduces himself and Mountain View Dairy, where he manages three facilities and associated farm ground. He outlines the design and construction timeline of their fully enclosed feed center and shares the three primary benefits behind the project: reduced shrinkage, improved ration consistency, and enhanced employee safety. (1:41)
Greg explains how external receiving and intentionally separated traffic flows eliminate cross-traffic between loaders and delivery trucks, which significantly improves safety and efficiency. The group discusses early design considerations, lessons learned from other operations, and how “R&D” (rob and duplicate) helped shape the final layout of the facility. (2:32)
Scott and Walt introduce footage showing how feeds are received, stored, and staged. Greg walks through the grain elevator, unloading, conveyor systems, bay storage, and handling efficiencies that minimize ingredient touches. (5:03)
Greg explains how strategic ingredient placement and facility layout shorten cycle time for high-use ingredients while maintaining flexibility for premixes and specialty feeds. He then goes into inventory management strategies, including rotating bins, tracking shrinkage, and maintaining ingredient freshness. (6:32)
The conversation shifts to dust control and shrink reduction, highlighting the enclosed facility design and the use of an industrial baghouse system to recapture nutrients. Feed processing is simplified by reducing complex operations to just a few controls. Greg highlights the impact of reducing corn handling to a single touch and how it accelerated ROI.  (8:28)
Finally, Greg discusses ration delivery innovations, including feed staging on conveyors and a custom delivery box that allows multiple loads to be staged and delivered efficiently. He shares how learning from other operations and refining those ideas to fit their scale and how it played a critical role in designing a system that maximizes efficiency without sacrificing flexibility. (15:08)
As we look ahead, join us for the next Real Producers Exchange on Tuesday, February 17, 2026, featuring Skylar Gerke, an Arizona dairyman with Midwestern roots. Skylar brings a unique perspective on what it’s like to transition from Midwest dairying to operating in the West. Registration is now open at balchem.com/real-science or agproud.com/real-producer. And as always, thank you to Walt for riding shotgun once again, and to our loyal listeners—thanks for being part of the journey. (20:39)

This episode’s guests were speakers on the Joint ADSA-CSAS Breeding and Genetics Symposium:
Dairy Welfare—Breeding and Management Strategies at the 2025 ADSA annual meeting. 
Jessica’s talk was titled “Herd Sustainability Index: Using milk recording data to evaluate dairy herd sustainability.” This index provides a national percentile ranking benchmark for producers relative to sustainability from DHI data. The index evaluates ten indicators in four major categories: longevity and culling, feeding and production, heifers, and health. (2:51)
Dr. Vasseur’s talk was titled “Improving welfare through inclusive innovation: The story of WELL-E.” This inclusive innovation delivers data-driven solutions with and for the Canadian dairy industry by integrating stakeholder and domain knowledge with cutting-edge tools and methods of the improvement of animal and human welfare. (4:48)
Dr. Vasseur talks about the development of the Code of Practice for the Care and Handling of Dairy Cattle, which was published in 2023. This most recent code of practice included recommendations and requirements for more opportunities for movement for dairy cattle, particularly those in tie stall environments. Dr. Vasseur’s lab has conducted research in this area to help dairy producers with possible modifications of stalls and other recommendations to improve cow comfort. Jessica describes her master’s research in tie stall modifications. The guests go on to talk about how often cows in tie stalls bump into their stall, some proof-on-concept research looking at doubling stall size, and recommendations for cow comfort improvements in existing tie stall operations. (6:53)
Dr. Vasseur discusses the relationship between cow comfort and longevity. She also talks about the realities of converting a tie stall barn to a free stall barn. (20:12)
Jessica describes the indicators used in the Herd Sustainability Index in more detail. A minimum of six tests in the last 12 months with 50% of the cows being recorded are needed to calculate the index for a farm. Seven of the ten HSI indicators are required for the index to be calculated. She goes on to explain how producers can see their index compared to the rest of Canada as well as historical change in their index, and details an incentive program for high-indexing and most-improved herds. (24:07)
Dr. Vasseur talks about cow comfort and welfare comparisons among intensive dairy production countries. She envisions the development and implementation of technology to allow for more automation and reduced observer bias of processes such as lameness evaluation. (30:30)
So what is WELL-E? Dr. Vasseur gives some background and details about bringing together animal scientists, computer scientists, and stakeholders to develop cutting-edge tools for the improvement of animal and human welfare. (33:24)
Jessica talks about her PhD research in dairy cow behavior and pasture management. She conducted a study where pastures were mowed the morning of grazing compared to conventional grazing. Cows in the mowed pastures spent more time ruminating and drank more water, but no differences in milk production or milk components were observed. (38:02)
Panelists share their take-home thoughts. (43:07)

Rob and Adrian share their family’s journey, from Dutch immigrant roots to managing large-scale dairy operations in California and Colorado, and discuss how communication, leadership structure and disciplined decision-making have helped them successfully scale their operation. The conversation also dives into lessons learned from facility design, sustainability initiatives and the launch of a consumer colostrum brand rooted in dairy science.
Rob and Adrian introduce themselves and share their family’s immigration story and early dairy roots in California, including how prior generations entered the U.S. dairy industry. (1:01)
The Diepersloot’s tell the story growth on their dairy operations, including expansion in California, the decision to diversify geographically and the opportunity that led them to build Wolf Creek Dairy in Colorado in 2017. (1:29)
Rob and Adrian describe how they build and empower a strong leadership team, emphasizing the importance of hiring the right people, expecting managers to think like owners, and conducting efficient and candid meetings that focus on the entire business. (6:25)
The conversation shifts to facility design and operational successes in Colorado, including no-headlock systems, sort gates, feed efficiency improvements, and later adopted in California. (9:59)
Sustainability initiatives are explored, including methane digesters, power generation, manure management and solar energy projects, with a comparison of approaches between California and Colorado. (11:10)
Rob and Adrian share lessons learned from technology challenges, including manure handling systems, activity collars, and feeding infrastructure, and how those experiences shaped future decisions. (15:46)
The discussion turns to the origin of WonderCow Nutrition, detailing how academic research on colostrum and personal family experiences led to the launch of a consumer colostrum brand in 2023. (17:47)
Rob explains WonderCow’s calf-first sourcing commitment, how colostrum is collected responsibly, and what differentiates whole colostrum products from skim-based alternatives. (20:19)
The episode concludes with a preview of the exclusive “Back 30” live Q&A, available only to live webinar attendees, and a reminder of upcoming Real Producer Exchange events including the next one on February 17 with Skylar Gericke out of Arizona which will focus on reproduction success and heat stress. (23:23)

In the Real Science Exchange Legacy Series, we celebrate the pioneers who have shaped the dairy industry. In this episode, we honor Dr. Don Beitz, a distinguished professor at Iowa State University. At the 2025 ADSA Annual Meeting, a symposium was held titled “Donald C. Beitz Recognition Symposium: 50-Plus Years of Dairy Science Research.” The guests on this episode, all former graduate students of Dr. Beitz, were speakers at the event. Join us as we explore Dr. Beitz’s contributions and enduring impact on our industry. 
Panelists introduce themselves and how they met Dr. Beitz. Tricky MS and PhD exam questions are also shared. Panelists emphasize Dr. Beitz’s love for biochemistry, teaching, and collaboration. (1:17)
Dr. Beitz shares about his early life, academic career, and family. (11:45)
Dr. Goff’s symposium presentation focused on Dr. Beitz and colleagues’ contribution to our understanding of transition cow hypocalcemia. He talks about studies on low calcium diets, investigating the metabolic pathways of vitamin D, and low phosphorus diets. Dr. Beitz also studied the impact of vitamin D on meat tenderness. (22:37)
Dr. Nelson’s presentation detailed the advances in understanding bovine immunology from the work of Don Beitz and his colleagues. From the milk fever vitamin D research, it was also discovered that vitamin D had an impact on the immune system, which led to further work with vitamin A and immunity as well. Dr. Beitz also had students investigate calf growth rate influence on immune system development as well as Johne’s disease. (27:22)
Dr. Drackley focused on Dr. Beitz’s work in understanding fatty liver and ketosis. The transition period was of interest to Dr. Beitz, which is reflected not only in his work in hypocalcemia, but also the lipid and carbohydrate metabolism of ketosis. Dr. Beitz and his colleague, Dr. Young, developed a successful ketosis model using a slight feed restriction and supplementing a ketone body precursor, which was used to investigate ketosis and fatty liver. (30:25)
Dr. VandeHaar spoke about Dr. Beitz’s passion for research and teaching in dairy science, biochemistry, and life. He emphasized the depth and breadth of Dr. Beitz’s work and teaching. He shared that Dr. Beitz has served as major professor for around 107 graduate students and has taught biochemistry to over 16,000 students. (35:02)
The panelists share stories about Dr. Beitz’s humility, care and support for students, and the many different professional societies he has been involved in over his career. (38:39)
Panelists share their take-home thoughts. (42:56)

This episode features Dr. Glen Broderick and Dr. May Beth Hall, speakers at the 2025 ADSA Ruminant Nutrition Symposium: Anomalies in Analyzed Nutrient Composition of Feedstuffs.
Dr. Broderick’s presentation was titled “Protein analysis methodology.” The high points of his talk include recommendations for nitrogen analysis in feeds, potential improvements in determining protein degradability and undegradability in the rumen, and near-infrared spectroscopy (NIR) analysis of amino acid composition of feedstuffs. (7:57)
Dr. Hall’s presentation was titled “Success and continuing challenges in analyzing nonfiber carbohydrates.” She gives some history of the analysis of non-fiber carbohydrates and talks about starch assays and how water-soluble carbohydrates are not solely composed of sugars. She also explains how microbes make decisions on which substrates to ferment and which to store for later. (12:47)
The panelists talk about challenges in obtaining real-time nutrient analyses in order to make ration changes. They recommend using rolling averages rather than a single sample and using milk urea nitrogen as a way to evaluate if something is not quite right with a ration. (21:17)
Dr. Broderick notes he recommends that scientists no longer use the Kjeldahl method of nitrogen analysis, that we look for new or alternative methodology other than in situ digestibility to determine protein degradability, and that NIR analysis of amino acids be used to make ration decisions when calibrated for the feedstuff under consideration. (27:10)
Dr. Hall recommends using the appropriate carbohydrate standard when measuring water-soluble carbohydrates: sucrose for fresh forages, fructose for cool-season grasses with high fructan content,  etc. She also notes that some feeds, like bakery waste or amylase-modified grain, contain soluble starch, which shows up in both the starch category and the water-soluble category in a feed analysis, essentially double-dipping. Lastly, she suggests that nonfiber carbohydrates remain a bit of a nutritional black box and we continue to learn more with improved technology.   (29:36)
Panelists share their take-home thoughts. (43:31)
