Microbiology results suggest that a rest stop during long-distance transport may increase the risk of BRD in newly weaned beef calves.

Do transport rest stops put calf health at risk?

Research on the Record with Reynold Bergen

By
The Canadian Food Inspection Agency revised the Transportation of Animals regulations a few years ago. Among other things, the revised regulations require longer and more frequent feed, water and rest stops during long-haul transport. Over the past few years, this column has summarized three research trials conducted by Dr. Karen Schwartzkopf-Genswein’s team at Agriculture and Agri-Food […] Read more

M. bovis, repeat offender

By
Police describe the suspect as being in his twenties with shaggy brown hair, wearing a black hoodie, white sneakers, blue jeans and a green backpack. He is known to associate with members of a criminal gang. If that was me, I’d be quick to cut my hair short, dye it gray, grow a distracting moustache […] Read more
The Canadian Cow-Calf Surveillance Network works with vet schools, private vets and 175 cow-calf producers to quantify health and management challenges and opportunities from coast to coast.

Record collectors unite: There’s power in numbers

Research on the Record with Reynold Bergen

Ranching without records is like travelling without a map. Records tell you where you’ve been and where you are. Connecting those dots tells you where you’re heading. If you don’t like that destination, records can help you decide how to adjust your management. When producer records are combined, you can tell where you are with […] Read more

Succession planning in the world of research

Research on the Record with Reynold Bergen

By
There’s been a lot of talk about succession planning in agriculture recently. Succession planning is just as important in research. Here’s an example. Surya Acharya started with Agriculture and Agri-Food Canada in 1989. He and his teammates developed two new cicer milkvetch varieties (AC Oxley II and AC Veldt), two sainfoins (AAC Mountainview and AAC […] Read more

Forages offer protection from flooding

Research on the Record with Reynold Bergen

By
Manitoba’s Hydrologic Forecast Centre predicted a major risk of spring flooding along the Red River a few days before this column was written. Spring floods are an annual concern in Manitoba. High precipitation, heavy soils and a flat topography mean that floodwaters can spread with devastating consequences, especially when ice jams prevent meltwater from flowing […] Read more
Identifying genes that play key roles in stress tolerance will help to breed alfalfa that is more resilient to environmental challenges.

Improving alfalfa’s flood and drought tolerance

Research on the Record with Reynold Bergen

By
One of last year’s research columns bemoaned the fact that only four out of 119 alfalfa varieties registered in Canada between 2012 and 2022 had been developed in Canada. The rest were from China, Australia or the U.S. Since then, the Canadian Food Inspection Agency (CFIA) has approved nine more varieties originating from Washington, Wisconsin, […] Read more
One study used laboratory measurements and eight trained sensory panellists to compare the eating quality of 100 dark-cutting steaks to 100 normal steaks.

Can Canada reduce dark-cutting discounts?

Research on the Record with Reynold Bergen

By
When cattle are severely stressed before slaughter there’s an increased risk that the rib-eye will remain dark red instead of blooming to a bright red colour. This phenomenon is called dark cutting. Extremely dark fresh beef isn’t visually appealing to consumers and has a shorter shelf life, so Canada’s grading system assigns these carcasses to […] Read more
Stress matters as it depresses a calf’s immune system and increases the risks of disease.

Keeping calves healthy

Research on the Record with Reynold Bergen

By
Cow-calf margins get tighter each time you feed a pregnant cow through the winter, only to have her calf die before weaning. Three leading causes of pre-weaning death loss are diarrhea, navel ill and bovine respiratory disease (BRD). Not all calf illness and death can be prevented, especially when the weather gets bad, but remembering […] Read more
A variety of alternative growth promoters have been marketed as natural replacements for conventional productivity-enhancing technologies.

Can we replace growth promotants?

Research on the Record with Reynold Bergen

By
Hormone implants and feed additives such as ionophores (e.g. monensin/Rumensin), beta-agonists (e.g. ractopamine/Optaflexx) and MGA (to suppress heat in heifers) have allowed Canada’s feedlot sector to dramatically improve growth rates, feed efficiency and environmental performance. In-feed antimicrobials to prevent liver abscesses (e.g. tylosin) also have an indirect benefit because healthy cattle grow better. While consumers […] Read more
