News and Updates for the 2018 Annual Meeting

Meet Geoffrey Dahl
Incoming ADSA President

Dr. Geoffrey E. Dahl, Professor in the Department of Animal Sciences at the University of Florida, Gainesville, assumed the role of president of the American Dairy Science Association® (ADSA®) during the 2018 ADSA Annual Meeting held June 24 to 27 in Knoxville, Tennessee.

Dahl will serve as president of the association for one year. Dr. Dahl served as vice president of the organization for the past year on the Board of Directors for ADSA from 2011 to 2014.

He has served as the ADSA representative to CoFARM from 2005 to 2008 and served as Production Division Secretary (2010-11), Vice-Chair (2011-12), and Chair (2012-13). Geoff served as Overall Program Chair for the JAM in 2013 and again in 2015. He has been a member of the Journal of Dairy Science Editorial Board since 2001, became a Physiology & Management Section Editor in 2008, and served as Senior Editor from 2012 to 2014.

Dahl grew up on a dairy farm in Massachusetts and received his B.S. in Animal Science (with a minor in Food & Resource Economics) from the University of Massachusetts in 1985. Geoff completed his M.S. in Dairy Science at Virginia Tech in 1987, and earned his Ph.D. in Animal Science from Michigan State University in 1991.

He then spent 3 years as a Postdoctoral fellow in the Reproductive Sciences Program at the University of Michigan, before joining the faculty at the University of Maryland in 1994. At Maryland, he served as Associate Professor and Undergraduate Program Coordinator in the Department of Animal & Avian Sciences.

Prior to his current appointment, Dahl served as Professor and Extension Dairy Specialist in the Department of Animal Sciences at the University of Illinois, Urbana-Champaign (2000-2006). He has been an active member of ADSA since 1985, and has served as a member and chair of the Lactation Biology and Growth & Development committees, and the selection committees for the Cargill Young Scientist Award, the Merial Dairy Management Award, the Genevieve Christian Student Award, and the Pfizer Animal Health Award.

Dahl previously served as Chair of the Department of Animal Sciences at Florida from 2006 to 2018, and served as liaison between the university, livestock producers, and allied industries.

In addition to his administrative responsibilities, Dahl conducts applied and basic research with direct impact on dairy production. Specific research interests include effects of photoperiod manipulation on production and health, the impact of frequent milking in early lactation on milk production, and heat stress abatement during the dry period on cow productivity and health. Dahl's extension activities included financial decision support tools for producers and development of on-line delivery of information and training to dairy producers and industry professionals. He has taught courses on dairy management, general and lactation physiology and endocrinology at the undergraduate and graduate levels.

Dahl has authored over 110 peer-reviewed papers and numerous symposium and popular press articles. He has trained 22 graduate students and post-doctoral fellows. Dahl received the Agway, Inc. Young Scientist Award (1999), the Merial Dairy Management Research Award (2004), the Pfizer Animal Health Physiology Award (2008), and the West-Agro Award from ADSA (2014). He has also been honored for with the Award for Excellence in Off-Campus Teaching from the University of Illinois in 2006. Dahl is a member of several other professional and honorary societies including the American Society of Animal Science, the Society for the Study of Reproduction, and the Endocrine Society.
As President of ADSA, Dahl seeks to further solidify the strength of the Journal of Dairy Science as the premier conduit for dissemination of information related to dairy science knowledge, across the production to consumption continuum, and extend the reach of the JDS brand. In addition, he wants to further promote the annual meeting and Discover Conferences by expanding partnerships with other professional groups globally.

Effects of grass silage chop length explored

The particle size (PS) of a diet along with its fiber content is important to maintain optimum rumen function and animal performance. Studies to date largely have focused on the PS of alfalfa and corn silage (CS) with relatively little work on grass silage (GS) PS even though GS is predominant in the diets of cows in Northern Europe. 

The objective of a study reported by Usama Tayyab of Harper Adams University during the American Dairy Science Assn. annual meeting in Knoxville, Tenn., was that of evaluating the effect of GS chop length and diet GS:CS ratio on cow performance and milk composition.

Hoof health impacts Holstein cow behavior

Digital dermatitis is linked to approximately 50% of lameness cases in dairy cattle. These hoof lesions may alter cow feeding and estrus behavior.

Amber Adams of Washington State University reported during the American Dairy Science Assn. annual meeting on a study that investigated how different hoof lesion sizes and the healing status affect cow activity, rumination and feeding behavior.

Time for change for some raw milk indicators 
Steven Murphy of EAS Consulting Group, Alexandria, Va., provided an overview at the American Dairy Science Assn annual meeting on the current science related to regulatory standards used as indicators of conditions considered public health risks for grade A milk and milk products.

Requirements for grade A raw milk include temperature (≤7°C); bacterial limits (≤100,000/mL producer); drug residues (Not Found), and SCC limits (≤750,000/mL). While lower temperatures are ideal, Murphy said limited storage time reduces public health risks.
