Antimicrobial Resistance: Why Beating the Bugs is Futile
Dr. Guy Loneragan, Texas Tech University
We will discuss the basics of antimicrobial resistance, why it matters, and what causes it.  Examples from our research projects will be shared.  In addition, we will discuss some ways we might think about controlling antimicrobial resistance under the umbrella of antimicrobial stewardship.

Nutrition 2.0: The Increasingly Complex World of How Nutrients Work
Dr. Barry Bradford, Kansas State University
In the first century of nutritional science, the roles of nutrients as fuels, building blocks, and enzymatic cofactors were carefully worked out, and this framework continues to define most of our thinking about nutrient requirements. However, a variety of other mechanisms are now known to mediate nutrients’ effects on the animal, and these impacts don’t necessarily fit within the traditional paradigms. Nutrients can act by modulating the gut microbiome, by acting as cellular signals, by influencing a host of metabolic hormones, or through epigenetic mechanisms. We will review some examples of such effects and consider how this understanding should influence nutrition research moving forward.

Approaches to Mitigating On-Farm Pathogen Burdens
Dr. Bill Stone, Diamond V
A variety of approaches can be used to reduce the pathogen burden that occurs at the farm level. We will discuss the use of both conventional and nutritional interventions to improve herd health, public health, and animal performance.

Precision Dairy Farming in the Future – Can Technology Replace Cow Sense?
Mr. Aidan Connolly, Alltech
Big data in technology is all the rage, and the promise of its application in dairy farming is intriguing.  But can technology and AI fully replace human labor and the importance of cow sense and human judgment in operating a dairy farm?  The discussion will be provocative and the answers may surprise you!

Relationships Between Undigested and Physically Effective Fiber in Lactating Dairy Cows
Dr. Rick Grant, Miner Institute
As we learn more about rumen fiber digestion pools, we must also focus on the proper physically effective fiber content that optimizes dry matter intake and productive response. For some diet types at least, the proper particle size is related to the concentration of undigested fiber.

Determination of First Limiting Physical Factors in Corn Silage Hybrids: Modeling Multiple Pools of Ruminal aNDFom Digestion in CNCPS
Dr. Mike Van Amburgh, Cornell University
The CNCPS v7 has been developed and uses multiple pools of aNDFom to describe digestion and passage.  Forages have been analyzed that allow for this approach and when fully implemented, the effect of rumen digestion and rate of rumen emptying can be estimated, thus rumen fill becomes a quantifiable factor.   This paper will describe an approach using a large corn silage dataset to evaluate the corn silage hybrids based on what is first limiting rumen fill, total aNDFom intake or uNDF.

The Synergy of Choline and Fatty Acids for Optimized Nutrition
Dr. Joe McFadden, Cornell University
This presentation will discuss new insights related to choline and fatty acid metabolism with regard to hepatic health and nutrient partitioning.

Practical Solutions for Year-Round Sheep Milk Production
Ms. Niko Kochendoefer, Cornell University

Modeling the Nutrition-Environment Nexus
Dr. Kristan Reed, Cornell University
Dairy farms are complex, interconnected systems. Nutrient management planning requires consideration of how the impacts of management decisions percolate through the entire system. Whole farm models can simulate interactions and feedback that occur between different parts of the farm and help us to understand how feeding practices influence short and long term nutrient management.

Milk Analysis for Dairy Herd Management: Today and in the Future
Dr. Dave Barbano, Cornell University
How does mid infrared milk analysis work?   How well should laboratories agree on milk testing?  This presentation will discuss various testing models and equipment and provide and introduction to in the interpretation of herd management milk testing results.

Mid-infrared Milk Testing for Evaluation of Health Status in Dairy Cows
Dr. Heather Dann, Miner Institute
This presentation will discuss the use of mid-infrared milk testing to identify health issues in dairy cows. Milk analyses from Individual fresh cows and pens of fresh cows will be shared along with field application and interpretation.

Ron's Range of Scientific Inquiry

Creating a Resilient Herd Against the Microorganisms That Will Rob You of Productivity
Dr. Elliott Block, Arm & Hammer Animal and Food Production
Variable feed intake and milk production, bouncing component levels, off feed and digestive issues, reproduction and health issues that crop up, deaths by hemorrhagic bowel syndrome – These are the daily challenges that seem to elude rational explanations. Rations are balanced by qualified nutritionists with all feedstuffs analyzed, veterinary protocols are followed, you are compliant with reproductive protocols, yet you know that these issues are robbing cows of productivity and robbing you of revenue and profit. There are a few potential culprits that play a major role in these challenges and can make your herd less resilient to coping with them. Pathogenic and non-pathogenic organisms along with mycotoxins that are always present constantly challenge the cow’s ability to cope and respond. This presentation will discuss some of these issues and a few ways that can help the cow’s immune and digestive system bounce back from and deal with these challenges.

Of Cows and Men: Reviewing the Link Between Dairy Fat and Human Health
Dr. Eduardo Rico-Navarrete, Cornell University

Potential of Nutrients in Coping with Environmental Stress
Dr. Xingen Lei, Cornell University

Dietary Management of Hypocalcemia Through the Use of a Synthetic Zeolite A
Ms. Allison Kerwin, Cornell University
Although we have decreased the prevalence of clinical hypocalcemia within the industry, some degree of hypocalcemia still affects approximately half or more of cows in the days following parturition. In this presentation, we delve into the results of a study which observed the effects of feeding a synthetic zeolite A for the last 3 weeks of gestation as an approach for minimizing hypocalcemia.

The Bovine Milk Proteome: What’s In It and How Can It Be Manipulated?
Dr. Sabrina Greenwood, University of Vermont
The bovine milk proteome includes thousands of proteins. These proteins appear to be diverse in their functions, and many have known bioactivity, affecting calf and human health. This presentation will focus on defining the different protein classifications and their proportions within the milk proteome, and how nutrition can impact the milk protein profile being produced by dairy cattle.

Optimizing Productivity from Pasture Based Systems – Quantification of Nutritional Limitations
Mr. Michael Dineen, Cornell University
An overview of the management practices implemented in intensive pasture based systems to optimize dry matter intake and milk solids production will be discussed. Additionally, the benefits of in-depth feed chemical composition analysis will be discussed with examples of how this data, in synchrony with the CNCPS, can help unlock a greater understanding of the biology of the grazing dairy cow.

Creating a Nutrient Sustainability Stamp for Dairies Nationwide
Dr. Quirine Ketterings, Cornell University
Many industries have, in recent years, focused on development of Sustainability Performance Indicators, reflecting the desire by food processing companies to implement a profitable agricultural supply chain that protects the environment through adoption of sustainable practices. Such indicators should be fairly easy to derive, be verifiable, be meaningful, and responsive to change in management over time. With the nutrient mass balance assessment, we present a farmer-focused approach of a sustainability stamp for three key nutrients (nitrogen, phosphorus, and potassium). We will present 10 years of results for New York dairies that participated in the development of this approach, and compare this to developments in other states and internationally.
