Join us for the 40th ADSA Discover Conference on NASEM Nutrient Requirements of Dairy Cattle
Due to continued COVID-19 related travel and gathering uncertainties coupled with delays with the NASEM publication the dates for this 40th ADSA Discover, NASEM Nutrient Requirements of Dairy Cattle, were changed to August 30-September 2, 2021. The conference is being held as a hybrid program. Interest has been very high and both the in-person and virtual participation options have sold out. A waiting list is being maintained for both live in-person and live virtual participation registrations, but we encourage all potential registrants to consider the Recordings Only option. This provides convenient access to recordings of speaker presentations for viewing on your own schedule. Click here for “Online Registration” and current options. We are looking forward to having you participate in our August program. We are here to help you however we can with questions and requests for support. Contact conference coordinator Molly Kelley or conference director Larry Miller with questions.
The National Academies of Sciences, Engineering, and Medicine (NASEM, previously known as NRC) anticipates the 2021 release of the eighth revised edition of “Nutrient Requirements of Dairy Cattle,” the world’s most highly cited reference on dairy cattle feeding. The expectation is that final release of all chapters will be after this conference. This DiscoverSM Conference will focus on the scientific advancements in dairy cattle feeding used to revise the 2001 edition. The NASEM subcommittee members will address the substantive changes in the nutrient requirements and the conceptual approaches used to make those changes. Participants will hear reports on areas with significant knowledge gaps that still prevent more accurate prediction of the nutrient requirements. Emphasizing the interactive spirit of Discover Conferences, the agenda will incorporate structured small group discussions, including a demonstration of the software and focused discussions with the speakers. The program will bridge the fundamental science to applied dairy cattle feeding.
Conference Topics
- Feed Intake, Fats, Carbohydrates, and Energy
- Proteins and Amino Acids
- Minerals, Vitamins, and Water
- Dry Cows, Calves, and Replacement Heifers
- Using the Model
- Application of the New Requirements
Expanding to a hybrid conference format allows us to offer meaningful collaboration among our colleagues throughout the world in the manner that best meets individual needs. We hope that you will join us for this redesigned event and celebrate our collective resilience and dedication to forging connections without boundaries.

NANP Nutrition Models Workshop
By Leoni F. Martins
The NANP (National Association of Nutrition Professionals) Nutrition Models Workshop was a great opportunity for attendees to deepen their knowledge in the use of equations and statistical resources to predict and evaluate the responses of animals when applying nutritional models. Despite the workshop being focused on dairy cows, professors, scientists, professionals and students left the event with a strong background about the concepts behind the mathematics and statistical parameters and how the biology of the animals can be properly fitted and predicted by the models.
The first section introduced attendees to the statistical software R and familiarized them with its functions and settings. The rest of the workshop consisted of a mixture of theoretical explanations and applied exercises where attendees had the opportunity to try modeling. Participants also learned how mechanistic models could be used to estimate real-world system parameters while reducing the distance between the estimation of a variable and its real observation by working on a case study of rumen protein digestion. Thereafter, the concepts of cross validation and bootstrapping were introduced to guide attendees in how to choose a best model associated with the lowest prediction error rate and how to determine the uncertainty of parameter estimates. The concept of automated model selection was then presented by the lecturer that illustrated how this procedure can be used in the development of empirical models in Animal Science. Lastly, the concepts and theories of rumen digestion, nutrient metabolism and lactation physiology were translated into mechanistic mathematical equations and combined into a dairy cow model (Molly) composed of a digestive and an animal element, wrapping up all the main concepts and examples presented on the workshop.
Leoni F. Martins is from Brazil, and he is a research assistant at Penn State University under the mentorship of Dr. Hristov. He has a strong background in ruminant nutrition, and he is currently working on how precision feeding affects performance and enteric gases emissions of dairy cows.

Norm Olson Symposium focuses on research contributions
By Aakash Varsha Swaminathan
Norm Olson Recognition Symposium was a walk down memory lane that revolved around the career and contributions of Dr. Norm Olson to the field of dairy science. Dr. Norm Olson graduated with a Ph.D. from the University of Wisconsin-Madison and went on to become a professor at the department of food science. During his work as a faculty for over 40 years, Dr. Olson worked towards establishing the Walter V. Price cheese research institute which eventually became the Wisconsin Center for Dairy Research (CDR) established in 1986 and Dr. Olson was named as the first director of CDR. This symposium provided insights on different areas of research that Dr. Olson worked on, shared by his former students and colleagues in 4 separate presentations. The topics of presentations included (1) “What I will always fondly remember about Norm Olson” by Mark Johnson of CDR, (2) “The biochemistry of cheese ripening and acceleration of its maturation: Overview and the contribution of the late Dr. Norman F. Olson” by Dr. Paul McSweeney, a professor at the University of College Cork, (3) “Cheese structure: The beginning of cheese quality” by Dr. David Everett, Strategy lead-Foundational Sciences, AgResearch, New Zealand, and (4) “Rennet coagulation: A critical but complex process” by Dr. John Lucey, director of CDR and Professor at the department of food science, Madison. In addition to Dr. Olson’s research contributions, these presentations also highlighted his contributions as a teacher, mentor, a leader for CDR, and as a human being.
Mark Johnson shared that Dr. Olson offered him his first job at the UW-Madison and he has since stayed on for over 40 years and is currently the Assistant Director and a distinguished scientist at CDR. In his presentation, Mark shared about the various different awards that Dr. Olson was awarded over the years. He mentioned that Dr. Olson was actively involved with American Dairy Science Association (ADSA), once served as a president, and also hosted one of the ADSA annual meetings at UW-Madison in 1983. Mark shared that Dr. Olson was a wonderful teacher and mentor who used a very hands-on approach. Dr. Olson handled various courses including the cheese-making class (2 weeks long where the first week focused on lectures and the second week focused on cheese tasting), food fermentations with lab, and sensory testing. Mark spoke about the beginnings of CDR and the initial industry-sponsored projects that he worked on along with Dr. Olson. He mentions that Dr. Olson had many international friends in cheese research and that Dr. Olson would invite them to CDR to discuss and share their knowledge on the same. Dr. Olson also started the cheese research forum which was organized to serve as an opportunity for the cheese industry partners to hear about the ongoing graduate student research projects. Mark ended his presentation on a light note by sharing a few Ole and Lena jokes (Scandinavian origin) that Dr. Olson had a great propensity for and would always share one of the jokes during the start of a meeting.
Dr. Paul McSweeney shared in his presentation that he was a Ph.D. student who visited CDR and was under the guidance of Dr. Olson for a year (1991-1992). He shared a few photographs that were taken in 1991 including Babcock Hall, a car that he owned, and a picture of him along with David Everett who was also one of the speakers of this session. Dr. McSweeney shared Dr. Olson’s contributions in the biochemistry of cheese ripening through 4 specific topics including lactate pentahydrate crystals, proteolysis, acceleration of cheese ripening, and pink defects. He explained the background and the chemistry involved in these specified topics and simultaneously mentioned Dr. Olson’s contributions to each of them. He also shared about something unusual that Dr. Olson i.e., Analyzing the microbiology and chemistry of 105-year-old cheese which was found on the bottom of Green Bay, Lake Michigan. This work of Dr. Olson was later published in the Journal of Dairy Science in 1970. Dr. McSweeney ends his presentation by saying that “Dr. Olson was universally respected and had an international reputation as a major leader in the dairy research. Norm was extremely kind to me and somebody with his stature could still remain as an utterly decent human being”.
Dr. David Everett was a Ph.D. student under the guidance of Dr. Olson at UW-Madison. In his presentation, Dr. Everett highlighted the research and collaborative activities of Dr. Olson in regard to cheese structure by going through three periods of cheese structural publications (1) protein structure 1962-1982, (2) cheese minerals (calcium lactate) 1986-1990, and (3) fat globule structure and surface chemistry 1995-2003. Dr. Everett shared in-depth about Dr. Olson’s research contributions in this area by presenting results of a few specific research papers that pertain to these above-mentioned topics. He also spoke a little bit about the state of cheese research globally and concluded his presentation with the following remarks from Dr. Olson from one of his papers “…developments in the cheese industry and the evolutionary and revolutionary changes during the past 25 years (are discussed). There is every reason to believe that such changes will continue for the next 250 or 2500 years”. Dr. Everett mentions that Dr. Olson was a great mentor, a true gentleman, and that he learned a lot from Dr. Olson as an educator and as a scientist.
Dr. John Lucey, in his presentation, highlighted the contributions of Dr. Olson on rennet coagulation. He explained how rennet clotted milk remained a mystery for a long time and how we came about understanding this reaction over the years through pioneer research. Dr. Lucey states that today we know that the rennet coagulation in milk is a 2-step process: (1) enzymatic phase (kappa-casein is hydrolyzed) and (2) Aggregation stage (flocculation of curds and aggregation). Dr. Lucey mentions that Dr. Olson in the 1970s worked on understanding the various factors that affected the secondary phase of milk clotting. He also mentions that Dr. Olson was interested in new techniques and technology and that he used a new rheological testing method to study and explore the then-upcoming research on concentrated milk (UF milk), the effect of pre-acidification, starter cultures, rennet addition, and pH on the effect of rheological properties in cheese. Dr. Olson also studied the kinetics of milk coagulation and came up with a theoretical model which still holds true for today’s research shares Dr. Lucey.
The session ended with Q&A from the audience and discussion among the speakers to reminisce Dr. Olson’s contributions and him as a person. To summarize as Dr. Paul Kindstedt, professor, University of Vermont, put it in his words, “Great symposium and great memories of a great cheese scientist, a very good friend and a wonderful human being…we miss you Norm”.
Aakash Varsha Swaminathan (Varsha) is a Ph.D. student in the Department of Food Science at the University of Wisconsin-Madison. She is under the guidance of Dr. John Lucey and her research work is on Modeling functionalities of LMPS Mozzarella based on calcium balances during cheese manufacture.
