Canadian research team to expedite improvement in productivity of domestic beef sector


 

A multi-agency research team led by University of Saskatchewan (Canada) veterinary reproductive biologist Dr. Gregg Adams aims to make fast strides in improving the productivity, efficiency and sustainability of Canada's $18-billion beef sector.

 

The effort would be achieved by integrating advances from the field of omics into livestock production.

 

"USask (University of Saskatchewan) has an amazing facility and programme centred around the Livestock and Forage Centre of Excellence, and expertise in all areas of livestock production, but one thing that has been missing is a genomic component," said Adams.

 

Genomics and other omics tools in biological science - such as phenomics, microbiomics, proteomics - involve the study of the appearance, structure and behaviour of animals, their microbiomes and cell proteins. Researchers have made tremendous progress in these areas over the past decade, and they can now use these advanced tools for extensive livestock production, Adams said.

 

Canada's beef cattle industry is tremendously important in its western region, with Saskatchewan and Alberta accounting for 70% of the country's beef production, Adams said. Consequently, even incremental changes in performance translate into big gains in economic value and job growth.

 

Adams' integrated omics for sustainable animal agriculture and environmental stewardship (IntegrOmes) project has been awarded $6.75 million over five years by the Canada Foundation for Innovation, with another $10.1 million expected from institutional partners, private industry and vendor in-kind support.

 

By bringing together experts in microbiology, epidemiology, reproductive biology and forage nutrition, the project aims to integrate the advances in omics tools to address challenges in the beef industry such as disease management, fertility improvement and environmental impact mitigation.

 

The first step is to gather reams of previously unavailable behavioural and other physical data on beef cattle by placing multispectral cameras in pastures and close confinement areas and linking the information with gene markers for desired traits, Adams explained.

 

"Once we identify these markers - the genomic characteristics that relate to performance, we can actually begin to collect the genetic material - the germplasm, embryos and semen from those individuals that have desirable characteristics," he said. 

 

The goal of IntegrOmes is to make it easier for cattle producers to identify and breed animals with desired traits such as better meat quality, stronger disease immunity, healthy uterine and semen microbiomes, shorter gestation periods, and good maternal behaviour and heavier calf weights at weaning.

 

To accommodate the collection, processing, sorting and cryopreserving of bulls' semen and cows' eggs, and creating and preserving embryos, IntegrOmes is establishing a biobank at the LFCE that fits hand-in-glove with the genomic tools researchers will use. The biobank will serve the needs of the beef livestock industry as well as bison conservation efforts - the other facet of Adams's research included in the CFI award.

 

IntegrOmes researchers are also using genomics to develop rapid diagnostic tools for diseases and antimicrobial resistance that have been problematic for the beef industry.

 

"If we can put these tools in the hands of diagnosticians or farmers themselves, they can report the results immediately - within hours or a day rather than having to wait days or even weeks - then we can cut the head off an epidemic, or certainly focus on appropriate antibiotics," said Adams.

 

"This project has been two years in the making, and it's created a lot of enthusiasm and momentum. Once the infrastructure and equipment are in place and we become proficient in its use, the impact will be felt for a generation or more."
