In this study genetic parameters of weekly average milk MIR-predicted CH4 production (PCH4) and its genetic correlations with milk yield, fat yield, and protein yield were estimated using a large number of PCH4 records in Canadian Holstein dairy cattle.

Dr. Edward (Ted) Burnside, one of the founder members and the first director of CGIL, was inducted into the Ontario Agricultural Hall of Fame on June 8, 2025. Dr. Burnside spent 31 years at the University of Guelph in teaching and research, and one of his major career accomplishments was his work in animal evaluation. In 1984, he co-founded and directed the Centre for Genetic Improvement of Livestock, which was instrumental in accelerating genetic progress, in turn resulting in many export spin-offs for Ontario genetics.
Exciting news from CGIL – our summer course is coming up fast! After a brief hiatus due to COVID, we are back at the University of Guelph to learn about a select topic in genomics research with Dr. Norbert Reinsch from the Research Institute for Farm Animal Biology (FBN). This one-week course will focus on parent-of-origin effects, especially on the epigenetic phenomenon of genomic imprinting. You will learn how genetic analyses may accommodate these effects and how appropriate models can be implemented in broadly used software programs. Spaces are limited so be sure to register in advance!
Projected climate changes will influence livestock production, an important issue for the dairy industry.
Lowered inputs with greater outputs for dairy farmers.
Association of milk production traits with weather data helps to identify heattolerant dairy cattle.
This issue of Animal Frontiers led by the Canadian Society of Animal Science covers prospects for exploiting epigentic effects in livestock production.
