How do hock injuries heal?

Cows can experience skin lesions on their hocks. Researchers studied how housing environment affects healing of hock injuries.

Field data identify cows with greater resilience to heat stress

Researchers used weather and production data from across Canada to identify cows that maintained milk yield better under high temperature and humidity. This can allow for genetic selection for animals with greater heat tolerance.

New approaches to reduce the effects of inbreeding on fertility

Targeted genomic selection may help to reduce inbreeding and improve fertility while maintain other genetic gains.

Genetic selection to reduce methane from cows

Large multi-site research projects led by Dairy at Guelph geneticists are identifying more feed-efficient cows with lower methane emissions.

Optimizing calcium and vitamin D intake for children

Researchers looked into sources and adequacy of intake of calcium and vitamin D by young children

The science of validating grass-fed milk labels

Food scientists developed a method to confirm grass-fed milk labels based on the fatty acid profile of the milk.

Exploring immune response genotype under heat stress

Cows with favorable High Immune Response status may also be more resilient to heat stress.

Understanding the impacts of management practices on udder health during dry-off

Farmers have long used antibiotic treatment at dry-off to cure and prevent intra-mammary infection. But with health concerns growing over antimicrobial resistance, producers are looking for other management practices

Dairy calf management practices following disbudding are a major driver for wound healing

Farmers looking to improve pain management and wound healing following dairy calf disbudding procedures should consider the level of milk feeding as well as pain medication, according to University of Guelph research.

Identifying opportunities to improve calf health with transition milk

A new University of Guelph study suggests that dairy farmers feed newborn calves milk from their dam for several days after colostrum feeding to help ensure health and prevent disease.

Oligosaccharide Yield

Understanding the impacts of transportation on dairy calf welfare

University of Guelph researchers expect that their new study will help improve calf welfare by determining effects of long-distance transportation.

Long Transportation

Understanding dairy farmers’ thinking
about antimicrobial use

With growing scrutiny of the use of antimicrobials in food animals, a University of Guelph study provides insights into how dairy farmers make decisions about antimicrobial use (AMU).

Next generation links — maternal and daughter health in dairy cows

Clinical disease has negative effects on dairy cow health and performance—but a new study shows the offspring of cows who have experienced disease are actually less likely to become ill themselves.

Health in Dairy Cows

What’s the best method to reduce calf disbudding pain?

University of Guelph researchers have found that a particular veterinary sedative may reduce indicators of pain during calf disbudding.

Herd management and milk production
in farms with automated milking systems

Improved milk production and quality on Canadian dairy farms are expected to result from a benchmark study on herd management and housing conditions conducted by University of Guelph researchers.

Herd Management

New technology assessment targets improved efficiency

A complete genetic and economic assessment of the current breeding structure in Canadian dairy cattle is in the process of being completed by a team of U of G researchers from the Department of Animal Biosciences. For more information, contact Prof. Christine Baes cbaes@uoguelph.ca or Prof. Flavio Schenkel schenkel@uoguelph.ca.
