Late-Breaking Original Research Session (half day, afternoon)

The 2018 ADSA Annual Meeting will include a session of late-breaking abstracts of original research that hopes to highlight a broad spectrum of work, including cutting-edge, high-tech research that was completed recently and is important to the species or discipline. Up to eight abstracts will be accepted from those submitted for the session. The authors of these abstracts will present their data at the Late-Breaking Abstract Session from 3:00 to 5:00 pm on Sunday. Authors of accepted abstracts for this session are required to prepare both an oral and a poster presentation. Oral presentations will include the speaker introduction, presentation, and question time in the usual 15-minute time slot. Posters of these presentations will also be available on Sunday (before the start of the oral session) and will remain on display for the duration of the meeting. This session is scheduled early in the program to allow networking with the presenting scientists and to avoid subject-matter conflicts.

Workshop: Dairy Records Analysis (full day, additional fee required)

Dairy Records Management System (DRMS) has developed reports to aid in analyzing dairy information for daily decision-making by herdspersons and consultants. In addition to these reports, DRMS’ PCDART herd assessment tools enable managers and advisors to analyze herd performance using either on-farm or downloaded data.

The primary goal of this workshop is to show participants how they can use a combination of DHI and PCDART reports to analyze dairy herd data and draw conclusions from the results. Data from the following herd management areas will be used as examples:

  1. Reproductive Performance
    1. Pregnancy rate
    2. Conception rate
    3. Services per conception for pregnant cows and for all cows; by parity
  2. Herd Health Assessment
    1. Udder health
    2. Reporting health data to DHIA and PCDART
    3. Prevalent health problems
    4. Inter-relationship between health problems
  3. Stocking Rate
    1. Replacement requirements
    2. Pregnancy rate requirements to satisfy replacement needs
    3. Decisions to keep or cull cows

This workshop will use a combination of presentations, discussions, and hands-on exercises with a maximum of 25 participants. Laptop computers will be required for hands-on exercises.

Workshop: Spore Sources and Transmission from Farm to Fork—Detection and Control Strategies (Half day, afternoon, additional fee required)

Spore-forming bacteria are known to play a role in the quality of a variety of dairy products, from fluid milk to dairy powders. These organisms represent farm-to-fork contaminants in that they enter the dairy product continuum at the farm level as well as in the processing facility. Therefore, minimizing product failures due to spore-forming bacteria requires a systems approach from production through processing. This workshop will address current research on spore sources, intervention strategies, and methods of detection, and will utilize industry knowledge on interrupting the transmission of spore-forming bacteria into dairy products.

Workshop: NANP Nutrition Models (full day, additional fee required)

The National Animal Nutrition Program (NANP) Nutrition Models workshop will use lectures and exercises to illustrate how mathematical models are constructed, evaluated, and applied toward problems in animal nutrition. Several modeling approaches are covered, but particular emphasis is given to dynamic, mechanistic models. The workshop will give attendees a basic fluency in mathematical modeling and, in so doing, advance their use of models in nutrition research.

ADSA 2018 Mini Symposium: Priorities for Fiber Research (DC33 Follow-Up)

The program for the 33rd ADSA Discover Conference “Integrated Solutions to Fiber Challenges,” held September 19–22, 2017, encompassed the following themes: Plants and climate; Animals and analysis; Animal by fiber interactions: impact of the plant on the animal; Animal by fiber interactions: getting the most out of fiber; and Modeling animals and fibers. Representatives from the conference summarized the challenges and recommendations from the three-day conference and conducted a survey of attendees to evaluate the relative importance of priorities in order to focus ongoing research to improve fiber utilization by animals. A mini symposium is scheduled for Sunday, June 24, from 2:00 to 3:00 pm to summarize the results from the September conference, convey the identified future research priorities, and discuss strategies to implement the priorities.

Discover Conferences, hosted by the American Dairy Science Association, address important contemporary issues in food animal agriculture and are organized to provide unique opportunities for professional interactions that will facilitate development and use of frontier science for the benefit of the global food industries and society. The conferences offer an environment that fosters creativity, emphasizes interaction and open discussion, and promotes the development and use of science. The mini symposium is an example of conference follow-up by a Discover program committee to further enhance the conference discussions, recommendations, and networking.

Animal Behavior and Well-Being Platform Session: Assessment of Affective States of Dairy Cattle (half day, morning)

An ever-growing body of research describes those factors that influence the welfare of dairy cattle. Scientific assessment of dairy cattle welfare includes investigations into effects on health and production, natural behavior, and the affective state of animals. Most research to date has been focused on the first two areas, with less attention being given to the final area (affective state). Many new research approaches are being used to measure affective state in dairy cattle, and this platform session will address those approaches.

Small Ruminant Platform Session: Addressing Management Challenges and Improving Performance in Small Ruminants (half day, morning)

The interest of small ruminants to the dairy industry worldwide and in the United States has increased in recent years, especially in areas where dairy cows have significant economic and social impact (e.g., US Midwest and Idaho). Since small ruminant dairy production has been mainstreamed in many places, we urge students and professionals to be aware of the unique aspects of small ruminant production. Mammary gland anatomy in the bovine and small ruminant has many similarities, but milk synthesis throughout lactation has many functional particularities in small ruminants compared with cows. Understanding the different mammary gland patterns throughout lactation is essential for today’s high-yielding dairy sheep and goats, and is critical for milking management strategies that have welfare implications. Management strategies for improving milk production with respect to behavioral peculiarities are key for producing value-added dairy products while enhancing the profitability and sustainability of any small ruminant business. This type of dairy production will also create long-term economic opportunities for people in resource-poor communities.

ARPAS Symposium: Sustainable Dairy Production (half day, morning)

The effects of agricultural production systems on the environment and the effects of regulations and climate change on animal production systems are areas of increasing concern for consumers, producers, and regulators. This has resulted in the need to better understand the vulnerability and increase the resilience of dairy production systems in the context of nutrient conservation and climate change and to better understand methods to conserve nutrients, mitigate greenhouse gas emissions, and adapt to new regulations and climatic variability. Speakers in this symposium will summarize the current regulatory climate for livestock operations and summarize current data regarding dairy greenhouse gas emissions and how they affect modeling of dairy production systems.

Reproduction: Joint ADSA-SSR Symposium: The Immune–Reproduction Nexus—The Good, the Bad, and the Ugly (half day, morning)

Control of the reproductive system is integrated with other physiological systems governing energy homeostasis, psychological stress, mineral metabolism, and so on. Fertility can be compromised when physiological functions are disrupted by adverse environments. A key regulator of reproductive function is the immune system. Indeed, recent evidence indicates that the implantation process evolved from a local, ancestral inflammatory response. The purpose of this symposium will be to highlight how the immune system can both facilitate the establishment and maintenance of pregnancy (the good) and lead to compromised ovarian (the bad) and uterine function during infection (the ugly). Prospects for manipulating immune function to enhance pregnancy will also be discussed.

Ruminant Nutrition: Management and Nutrition of Dairy Cattle in the New Era of Automation (half day, morning)

Whether it is an automatic calf feeder, a robotic teat-spraying arm, a self-guided feed pusher, or a whole milking system, an increasing number of dairy farms are incorporating automation into their regular operations. Common farming practices, including feeding strategies, may not be totally compatible with some of these technologies, and adjustments in management, feeding, and nutrition must be made to ensure proper animal performance.

Forages and Pastures Symposium: Fiber Digestibility—From Cell Wall Composition to Forage Utilization (half day, afternoon)

Highly digestible fiber from forages is critical for maximizing feed efficiency, sustaining health of the gastrointestinal tract, and ensuring profitability of dairy farming systems. The US dairy industry feeds approximately 23 million tonnes of fiber per year to lactating cows alone. In the last decades, the formulation of high-forage diets has increased substantially as a means to overcome challenges in rumen health and in volatile commodity prices. In this regard, forage quality and fiber digestibility are critical in ensuring maximum profitability when formulating high-forage diets for lactating dairy cattle. Climate change is an ongoing global concern that may influence forage yield and quality. Despite our existing knowledge about the effects of environment on forage yield and quality, specific information about the effects of abiotic stresses, such as drought and heat, on fiber digestibility is scarce. As a means to improve forage fiber digestibility, different technologies have been, or are being, evaluated for dairy cattle; for example, the production of forages containing reduced concentrations of lignin, the addition of exogenous fibrolytic enzymes to the diet, and the chemical treatment of forages. This symposium will feature lead researchers who will provide a holistic update of cell wall composition and fiber digestibility, from the basic aspects of cell wall organization and their impact on fiber digestibility to the practical aspects of ration formulation and fiber utilization.

Joint MILK and Lactation Biology Symposium: Milk Globules, Vesicles, and Exosomes—Update, Origin, Structure, and Function (half day, afternoon)

This year, our MILK Symposium’s topic is a particularly interesting one, because it deals directly with the potential of milk structure and components and its role in human health and wellness beyond basic nutrition. This year, the MILK Symposium brings together two currently developing areas in dairy science: lactation biology and food biotechnology, as well as current views of milk synthesis, structure, and function. Milk globules, vesicles, and exosomes constitute a topic of increasing research interest, and one in which dairy scientists and scientists of diverse disciplines working with milk have a great deal to contribute to our members. The presenters for this MILK Symposium and their insights promise to be highly motivating for students and young scientists.

Dr. Ian Mather has studied lactation for a long time, and his work in fundamental aspects of the unique origin of the most important food for all mammals has achieved a level of sophistication and complexity that is increasing our understanding on how milk is produced and secreted in the mammary gland.

Dr. Janos Zempleni is a pioneer in the area of exosomes in milk and has impressive developments in understanding their function. His research leads to the potential development of dairy foods in the future, where new delivery systems will result from our understanding of nature’s micro- and nano-vesicles.

Dr. Nurit Agrov-Argaman is currently studying the factors that influence the size of fat globules in the bovine mammary gland. The size and composition of the fat globules seem to be correlated with important functions in nutrition, which may hold the key for a smarter design of individualized food development. A fundamental understanding of how to regulate the size and composition of fat globules is a new perspective in milk production.

Dr. Harjinder Singh’s research group has a long tradition of exploring the relationship of structure and function of dairy foods, and the area of fat globules, vesicles, and their role in digestion is one of the latest areas in which Dr. Singh has developed novel techniques and constructed current views on the relationship of structure and function of dairy emulsions.

Dr. Rafael Jimenez-Flores has focused in the last 15 years on the study of the milk fat globule membrane (MFGM) and its potential in food nutrition and function. With new approaches to the analysis of MFGM and vesicle components and structure, models of innovation in foods with directed health and wellness targets may be possible.

Dairy Foods Microbiology Symposium: Whole-Genome Sequencing for Dairy Microbiology (half day, morning)

Whole-genome sequencing (WGS) is revolutionizing food microbiology. This new tool is providing dairy researchers, industry, and regulators with a broad range of new abilities, including (1) troubleshooting and tracking pathogen and spoilage organisms; (2) understanding the genetic regulation and subsequent metabolism of dairy cultures during fermentation; and (3) gaining a deeper perspective of how dairy cultures have evolved and how new directions in modern genetic techniques can be applied to these microorganisms. The breadth of WGS can be intimidating, and the goal of this symposium is to highlight recent applications of WGS that have effectively addressed and illuminated microbiological questions along the dairy supply chain.

Breeding and Genetics Symposium: Fertility—Filling the Gaps. (half day, morning)

Although genomic selection has maintained its promise for most traits under current selection and even for new traits (e.g., the recent implementation of disease resistance in North America and the substantial effort to increase efficiency currently underway), fertility perhaps remains the “trait” that has benefitted the least from genomic technologies, for several reasons. In this symposium, we aim to provide a comprehensive overview of the status of current research and the efforts needed at different levels to harness the full potential of new technologies/strategies to enhance fertility without compromising production. In particular, we are interested in how to (a) collect better phenotypes (closer to the biology of the cow, both for estrus detection and maintaining a pregnancy); (b) achieve a more exact understanding of physiology (and how to include it in genetics programs); that is, bridge the gap between veterinarians and geneticists; and (c) deploy selection tools that are of value for the industry/producers.

Ruminant Nutrition: Interface of Environment and Nutrition—Targeted Nutrition to Overcome Heat Stress (half day, morning)

The dairy industry loses billions of dollars annually due to heat stress. Although we have made great improvements in physical heat abatement strategies, we still have limited control of the ambient environment. Additionally, as an industry, we have made strides in breeding more heat-tolerant cattle but that often comes at a loss in the volume of milk produced. Even after environmental and genetic improvements, we have limited solutions for helping cows overcome heat stress. Recently, studies have been conducted to address heat stress at the cellular level and respond to changes by providing targeted nutrition.

Growth and Development Symposium (joint with Ruminant Nutrition): Post-Weaning and Beyond (half day, afternoon)

Most of our knowledge about weaning dairy calves and rumen development was generated decades ago using milk and solid feeding strategies that are very different from those in use today. With the recent adoption of new feeding strategies, such as elevated milk and automated feeding, weaning has become an even more critical period that can affect long-term growth, health, and potentially future productivity. In addition, as we continue to unlock the growth potential of preweaned calves by increasing feed intake, the recommendations for how to properly manage calves for the next two years need to be redefined. There has been a flood of research recently on this topic and this symposium aims to address the following important questions:

  • When and how to wean calves fed elevated levels of milk?
  • When to make dietary and housing switches while weaning?
  • How is rumen and intestinal development affected by weaning? Does this carry over into lifetime productivity? (A common question but not a lot of data yet.)
  • Do calves fed high amounts of milk experience impeded growth checks compared with calves fed high starter diets?
  • What is the best form of feed for calves post-weaning?
  • What is the role of the gut microbiome and gut physiology in post-weaning management?

Southern Section Symposium: Sustaining the Southern Dairy Industry: University Research, Teaching, and Extension Outlook (half day, afternoon)

This year's Southern Section Symposium will have a different twist than normal. The number of dairy farms in our region has decreased tremendously over the last few years, and as such, academic, outreach, and research programs at Southern universities have shrunk. This year, the ADSA Southern Section symposium will feature faculty and administrators who have demonstrated successful research, teaching, and extension programs in our region. The goal is to have a thought-provoking discussion about the status of our industry and shape the future direction. You will hear from Cathy Williams (Louisiana State University) about teaching and extracurricular programs focused on dairy science; John Bernard (University of Georgia), who will discuss a successful model for extension moving forward, and Michael Ballou (Texas Tech University), who will give insight into establishing quality industry relationships to support research activities. Also, Steve Smith from the US Department of Agriculture-National Institute of Food and Agriculture will join this set of speakers for a panel discussion just before the ADSA Southern Section reception. We will kick the session off with the Southern Section business meeting and hope that everyone can join us!

Animal Health Symposium: Bovine Tuberculosis—An Ongoing Animal Health Challenge

Bovine tuberculosis (bTB) is a devastating but poorly appreciated infectious disease that affects cattle but can also cause severe life-threatening disease in other domesticated and wild animals. It is endemic in many areas of the world and periodically reemerges in the United States and Canada. The public and many in the industry are not aware that bTB causes an untold number of human TB cases each year and that it contributes to an estimated US$300 billion in global economic losses due to lost livestock and income. The symposium will review the current status of the disease and efforts of combat it.

CSAS Symposium: Genomic Alterations and Implications on Health: Gut and Beyond

Over the past decade, the dairy research community has been adopting new molecular biology–based techniques in hopes of improving the breadth of research. The techniques within molecular biology have evolved quickly, encompassing high-throughput genomics, metagenomics, transcriptomics, decreasing, many researchers are now able to implement them as a means of better explaining biological systems. Where once a technique was applied only by geneticists, we now have nutritionists, physiologists, and immunologists integrating data from high-throughput methods, which has significantly advanced our understanding of dairy cow biology. However, these techniques also impose certain challenges—mainly interpretation of the underlying biology and integration of actual biological outcomes. Therefore, the aim of this symposium is to highlight how researchers are using “omics” techniques in their research program to explain the biology of the dairy cow in all major fields of dairy science.
