The Iowa State University Extension and Outreach Dairy Team monthly webinar series continues on Thursday, May 29, from 12 noon to 1 p.m. This program will be presented by Dr. John Cole discussing the impact of inbreeding in Holstein dairy cattle.
Genetic base changes include both corrections for observed genetic trends in the population and adjustments to account for inbreeding according to Dr. Cole. He will discuss how the observed changes in Predicted Transmitting Ability (PTA) for individual animals may not match the base change values as closely as they have in the past and how it is due to Estimated Future Inbreeding (EFI) changes in the population that are larger than they’ve been in the past.
Dr. Cole serves CDCB as the Chief Research and Development Officer. Before coming to CDCB, he spent three years as the Senior Vice President, Research and Development, for PEAK Genetics, where he oversaw genetics and reproductive biology research for the largest producer of cattle genetics in the world. Prior to joining PEAK, he spent 17 years as a Research Geneticist (Animals) and Acting Research Leader for USDA’s Animal Genomics and Improvement Laboratory (formerly the Animal Improvement Programs Laboratory). John has authored more than 150 peer-reviewed research articles, mentored many postdoctoral scientists and graduate students, and is a frequent speaker at industry and scientific meetings.
Producers, dairy consultants and industry reps are encouraged to attend the free webinar live from 12 noon to 1:00 p.m. on Thursday, May 29 by registering at least one hour before the webinar at:
