Roger Thomson, DVM, Milk Quality Consultant
The milking system is the heart of any dairy operation, and requires a lot of consideration! Dr. Thomson discussed the design and analysis of a milking system, including some reasons a producer might consider changing the milking system, frequency of evaluation, and basic system design. He also covered regular maintenance concerns and discussed the National Mastitis Council's analysis fundamentals and goals.
Ray Nebel, Select Sires
Many dairies experience difficulty in their reproduction programs, and a wide range of factors can affect reproductive success in a herd. In this session, Ray Nebel took a look at some of the factors that affect reproduction on dairies, including labor, nutrition, environment, and the cow herself. He also discussed how you can find and fix problems that could be affecting the success of your reproduction program.
Limin Kung, University of Delaware
With so many variables affecting the quality of silage, it can be difficult to manage the fermentation process to produce an optimal feed.

He covered the costs involved, factors that influence those costs, the economic impact of the replacement program on the dairy farm's performance, and several other factors to consider in a replacement program.
Dr. Micheal Brouk, Kansas State University
Unsure of where your dairy's feeding program might be leaking money? Dr. Brouk discussed how you can do a little detective work to identify some common sources of unseen feed costs in a dairy herd. Just a few areas he covered included commodity shrink, mixer errors, refusals, and expense of inventory.

There are many financial benchmarks and ratios a lender will use to evaluate a dairy farm’s financial position and progress. During this webinar, Gary sorted out and discussed 8 key items that are critical for a dairy producer to monitor.
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.
Dr. Victor Cabrera, University of Wisconsin-Madison
Drs. Cabrera and Fricke of the University of Wisconsin-Madison have been working to develop some new economic analysis tools for dairy reproduction programs. During this session, Dr. Cabrera discussed three main decision support systems, including the UW-DairyRepro$Plus and the Dairy Reproductive Economic Analysis. These tools are openly available at http://dairymgt.info/tools.php under the Reproduction heading.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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
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.

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.
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.
