New Tools for Dairy Reproduction Programs
Dr. Paul Fricke, University of Wisconsin-Madison
Dr. Fricke covered two areas of reproductive research that have investigated new tools for reproduction and conclude each with an economic analysis of the data. The first new tool will be the use of accelerometer systems combined with various levels of synchronization for submitting cows for first AI service. The second tool will be new methods for nonpregnancy diagnosis coupled with strategies for resynchronization of ovulation.

Far Off to Fresh Cow – Opportunities to Improve Transition Performance
Dr. Mike Overton, Elanco
A successful lactation starts well before calving. Going back to the completion of her previous lactation and entry into the far dry cow pen, how we manage and feed the cow well before she approaches calving contributes to the likelihood of her achieving a high level of milk production and conceiving in a timely manner. This presentation will “walk” through the opportunities and challenges in the far dry, close-up, and fresh pen, including nutritional and housing management, and discuss a few of the key monitoring approaches for evaluating performance.
Outcome Driven Health Management
Dr. John R. Wenz, Washington State University
The goal of the “Good Health Records” program at Washington State University (www.goodhealthrecords.com) is: Accurate and consistent health records, efficiently summarized, used to evaluate and inform management decisions on all dairies. "Good records" have long been recognized as a cornerstone of successful animal husbandry and are becoming increasingly important in the dairy industry as the size of herds has grown. However, industry-wide standards for recording and evaluating health data don't exist. Connect with us for this webinar to learn how to achieve truly “good” health records and use them to make health management decisions based on hard evidence (outcomes) from the cows rather than perceptions of people.
Better Milk Quality from Better Mastitis Therapy Decisions
Dr. Ron Erskine, Michigan State University
Mastitis is one of the biggest chronic problems facing the dairy industry- it is ever present. In this session, Dr. Ron Erskine will discuss how to better identify cases of mastitis through tools such as milk culturing, somatic cell count records, and treatment records.
Potential and Pitfalls for Genomic Selection
Dr. Chad Dechow, Pennsylvania State University
Dr. Dechow reviewed genomic technology and implementation, comparisons of early genomic predictions to actual daughter proofs, a discussion of inbreeding, and how genomics can be used as a herd management tool.
Feeding Systems for Group-Housed Dairy Calves
Dr. Mark Thomas, Countryside Veterinary Clinic
Nutrition is a vital part of calf health and development, and making sure that calves get the nutrients they need in an efficient manner is an important job! Dr. Thomas will review feeding systems for dairy calves in a group-housed setting. Tune in to learn about how to optimize nutrition, some practical concepts for ad libitum, acidified group feeding, to see comparisons of other available systems, and for a review of possible health benefits and challenges of feeding calves in a group setting.
Diagnosing Problems in Nutrition Programs Through Records
Dr. Greg Bethard, North Carolina State University
There are numerous points in a nutrition program where problems may arise, especially when you're dealing with transition cows. In this webinar, you can learn how to use records to track performance of transition and early lactation cows to diagnose problems in your nutrition program.
Can I Really Prevent My Cows from Becoming Lame?
Dr. Ernest Hovingh, Pennsylvania State University
Lameness is a painful, costly, common and complex problem - a problem with which too many dairies struggle. Dealing with a lameness problem not only involves identifying and dealing with lame cows in the herd, but trying to prevent new cases from occurring in the first place. This webinar will focus on a number of best management practices that farms can utilize to try to minimize the number of cows that become lame - even when milk prices and profit margins are low.
Cooling Strategies During Heat Stress
Dr. Pete Hansen, University of Florida
Cooling dairy cows is the most important strategy to improve both milk production and reproduction during summer months. Opportunities that dairy farms can utilize to evaluate the effect of heat stress on their dairy will be discussed. Also, various environmental modifications can be employed to improve cow performance and will be presented herein.
Economics of Heat Stress: Implications for Management
Dr. Albert DeVries, University of Florida.
Heat stress costs the American dairy industry approximately 1 billion dollars annually in production losses. Understanding the economic consequences of employing various strategies to reduce the effects of heat stress and how this affects the dairy farm’s profitability is important for producers to make economic decisions. Novel economic evaluation and approaches will be discussed to educate producers on cost effective strategies to improve summer fertility.
Nutrition Programs for the Heat Stressed Herd
Dr. Jose Santos, University of Florida
Proper dietary programs are essential to cow health and performance during heat stress. Understanding what dietary changes can be made prior to and during summer heat stress are important for assisting thermoregulatory mechanisms of our modern high producing lactating dairy cows to aid in reducing the negative effects of heat stress. Nutritional changes will be presented for producers and consultants to make informed decisions on the proper dietary changes necessary to reduce the severity of summer heat stress
Strategies to Improve Reproduction During Summer Heat Stress
Dr. Todd Bilby, Texas A&M
Reproductive failure is the number one reason dairy cows involuntarily leave the dairy farm and summer heat stress exemplifies this costly issue. However, managerial, hormonal and novel reproductive technologies are available for producers to utilize which will reduce the severity of summer heat stress on reproduction. The various strategies will be presented in detail to educate both producers and consultants to be able to implement reproductive program changes to subside summer’s negative effects.
Animal Welfare Certification Options
Dr. Jim Reynolds, Western University
Dr. Reynolds, Professor of Large Animal Medicine and Welfare at Western University College of Veterinary Medicine, discussed current options in animal welfare certification, along with the value of certification and how to determine if you should become part of one of these programs.

Managing TMR Variability
Dr. Tom Oelberg, Diamond V
Dr. Tom Oelberg discussed managing TMR variability through the use of TMR audits. He covered what a TMR audit is, as well as factors that affect TMR consistency such as bunker face management, overfilling, under-processing of hay, improper loading of liquid supplements, worn equipment, and under-mixing.
Appropriate Drug Use and Residue Avoidance Practices
Dr. Michael Apley, Kansas State University
Dr. Craig Shultz, Pennsylvania Department of Agriculture
Drs. Apley and Shultz discussed the why and how of drug residue avoidance, as well as appropriate usage of medications on dairy farms.
Here is an example record sheet for recording treatments given to cattle.
Human Resource Management: Being a Boss or Building Relationships
Bob Milligan, Dairy Strategies
Dr. Bob Milligan, Cornell University Dyson School of Applied Economics and Management Professor Emeritus and Senior Consultant at Dairy Strategies, LLC, introduced the audience to the current thinking in human resource management. Current research substantiates that great leaders and supervisors focus on relationship building, communication, clarity and feedback rather than command and control.
Handling High Commodity Prices
Normand St-Pierre, The Ohio State University
Dr. St-Pierre discussed how to control feed costs using various methods. These methods include: getting the full value of forage crops, purchasing ingredients that are favorably priced, inventory management, producing things that you are being paid for, managing the herd structure, cow grouping, and feed additives.
Impact on Air Quality and Climate Change- Where the Dairy Industry Stands
