Brief Summary of Minutes of Annual Meeting

May 25-27, 2016

 The joint S-1064 and WERA-1 meeting was called to order on May 25, 2016 by Dr. Jeremy Powell at the Great Hall on the University of the Virgin Islands Campus in St. Croix. Dr. Bob Godfrey invited everyone to enjoy the coffee and other refreshments and covered other general housekeeping items. All participants introduced themselves and provided a brief overview of their roles at their respective institutions. Dr. Powell took volunteers for the nominating committee (Bob and Jeremy) and resolutions committee (David and Bryan).   Dr. Godfrey gave an overview of the experiment station because it was the first trip to the island for most of the attendees.

WERA-1 reports were interspersed between S-1064 reports:

Milt Thomas reported on ongoing efforts at CGEL at Colorado State. He shared genomic research on grazing distribution collected with HD genotypes and GPS collars. He also shared PAP genetic trend data. PAP has a moderate heritability and making genetic change at high altitude is highly desired by producers. He also shared results from RNA sequencing of high and low PAP bulls. There were between 500 and 1000 genes differentially expressed between the high and low animals in a variety of tissues. He also shared results examining PAP measures and late feedlot death.

 David Schafer presented a WERA-1 report on the V bar V Ranch in Arizona. He described some of the research projects that are ongoing at the Ranch including breeding projects evaluating breed selection in that environment, brand healing rates between different times and coat colors, grazing distribution, and early weaning.

 Dr. Powell invited reports from the nominating and the resolutions committee for the S-1064 project group for the business meeting. Dr. Powell and Dr. Godfrey indicated that the nominating committee had nominated Bryan Kutz as incoming secretary for the S-1064 executive board. Bob moved we accept this nomination and it was seconded by Megan. His nomination was accepted by unanimous vote. The resolution committee report was read by Bryan. It was moved by Rhonda and seconded by Bob that we accept the resolutions and it was accepted by unanimous vote from the group. The resolutions are provided at the end of the meeting minutes.

 Dr. Joe West gave an administrative report, which was preceded by his encouragement for the group to band together and submit AFRI proposals. The project runs through 2019 and has been around in one form or another since the 1950s. He encouraged recruitment of new members and solicitation of new types of funding to grow the group’s expertise and ability to do research. Opportunities for recruitment for both S-1064 and WERA-1 were discussed. The group intends to continue meeting every other year with the WERA-1 group, so the next joint meeting would be in 2018. Next year, we will discuss where the joint meeting will be held. We reviewed the positions everyone would hold on the executive committee next year.

 We discussed meeting locations for next year. Gainesville, FL was nominated as the location for the next meeting in 2017. Bob moved that we go to Gainesville in 2017 and it was seconded by Bryan and it was approved by a unanimous vote.

 Tours included a tour on Wednesday afternoon of the UVI sheep farms and Annaly Farms, who are Senepol breeders who helped found the breed. On Thursday afternoon, we visited the AES Beef Cattle Facility at Estate Longford and ate dinner there. On Friday, May 27, we toured Buck Island National Park.

Accomplishments:

Objectives for this project are: (1) Develop, disseminate, and maintain resources on the genetics of beef cattle and comparative genetics among cattle breeds and other species (e.g, sheep, wildlife) to support outreach, extension, and education activities, (2) Maintain animal populations, DNA and RNA repositories, and performance and health databases to support beef cattle phenomics research, (3) Integrate quantitative and molecular research tools that contribute to the understanding of genetic associations among economically important traits and their indicators, and (4) Exchange information, discuss research results, plan new research, examine new developments, discuss future problems, plan cooperative research and share ideas for interdisciplinary involvement in beef cattle breeding.

For the upcoming year, committee members will continue individual and collaborative activities regarding data collection, analyses, publication and dissemination of results. Scientific and producer/stakeholder meetings will be targeted as outlets. The committee will assemble for an annual meeting. New funding possibilities will continue to be targeted.

Short-term Outcomes:

Increased knowledge has been attained of QTL for Mycobacterium avium paratuberculosis tissue infection in Holsteins and Jerseys.

Knowledge of BRD susceptibility loci in dairy and beef cattle has been improved.

Identification of genomic regions associated with BRD will allow investigation of causal mutations to benefit selection for BRD resistant animals.

Identification of genomic regions associated with beef cow stayability and longevity will allow investigation of causal mutations to benefit selection for fertility.

Bull test producers have been provided with detail performance data for improved selection and marketing decisions.

Knowledge of rumen microbial species potentially important to the regulation and prediction of feed efficiency in ruminants has been increased.

Increased knowledge of rumen microbial species as affected by high dietary sulfur has been attained.

Wolf genetics research was used by the U.S. Senate to inform the Fish and Wildlife Service that science does not support an Endangered Species Act listing of wolves in southeast Alaska.

During the past year participants have completed the training of 8 M.S. and 1 Ph.D. students.   

Research trials relating to microbial profiles to feed efficiency have been conducted.

Outputs:

During the previous year, project members provided 26 invited presentations to various state/regional, national, and international audiences.

Regional and state-level educational presentations were provided to youth and producer groups.

Project participants provided invited presentations at national meetings of the American Society of Animal Science, American Dairy Science Association, Academy of Dairy Veterinary Consultants, American Association of Bovine Practitioners, Beef Improvement Federation, and National Cattlemen’s Beef Association.

Participants provided invited presentations to international audiences from Argentina, Brazil, Colombia, New Zealand, Pakistan, and the Philippines.

Research output included 20 refereed manuscripts, 48 abstracts at scientific meetings, 11 conference proceedings, 1 patent, and 3 popular press articles.

Research publications included collaborating scientists from agricultural economics and wildlife population biology.

Complementary wildlife genetics research has led to publications with regarding feral cattle on Chirikof Island, Alaska, polar bear biology, sage grouse endangered species consideration. This collaboration also led to presentations at the Northwest Sheep and Goat Conference and The Wildlife Society Meetings.   

Activities:

Specific research activities:

WSU serves as the repository for the collection, DNA extraction and storage of feedlot samples from Washington as part of the BRD consortium. Samples now include 3000 Holstein and 2000 feedlot cattle samples with phenotypes, diagnostics and 778K genotypes. Additional samples of 500 feedlot cattle and 200 Holsteins (with diagnostics) have been collected.
