The Iowa State University Extension and Outreach Dairy Team’s monthly webinar series continues on Thursday, May 29, from noon to 1 p.m. This program will be presented by John Cole, chief research and development officer with the Council on Dairy Cattle Breeding. He will discuss 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 Cole. He will share
how the changes observed in Predicted Transmitting Ability for individual animals may not match the base change values as they have previously, due to larger Estimated Future Inbreeding changes in the population than in the past.
Before joining the Council on Dairy Cattle Breeding, Cole 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.
Cole 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 webinar live, which is available at no cost. Those who wish to attend should register online at least one hour before the webinar.
This webinar will also be archived for later viewing on the ISU Extension Dairy Team website.
