The rumen allows cattle to digest fibre that chickens, pigs and humans can’t, and produce high-quality beef protein from feed and land that otherwise wouldn’t produce food. Understanding the rumen better is the key to improving feed efficiency and improving cattle’s ability to convert fibre to protein. There’s as much energy in straw as grain — […] Read more

Timing cattle breeding for improved calf survival
Research on the Record with Reynold Bergen
I once spent a summer working for canola breeders. Some used traditional selection, while others were experimenting with transgenics. One traditionalist was known to say “sticking a new gene into a plant and expecting it to grow better is like throwing a new gear into a watch and expecting it to keep better time. It’ll […] Read more
On-farm antimicrobial surveillance moves a step closer
Research on the Record with Reynold Bergen
As long as cattle continue to get sick, cattle producers will need antimicrobials to help them recover. At the same time, it’s common to hear activists, regulators, consumers and/or retailers call for livestock producers to stop using antimicrobials altogether, reduce antimicrobial use, or demonstrate that antimicrobials are being used responsibly. Solid, reliable data demonstrating our […] Read more
Johne’s disease: Cheap to buy, costly to live with
“Biosecurity” often conjures up images of poultry or hog operations with truckers-report-at-the-gate signs, shower-in-and-out rules and workers dressed in hazmat suits. The point of biosecurity practices is obviously to reduce the risk that disease-causing microbes will enter or spread within high-health status herds or flocks. It is much harder to implement high levels of biosecurity […] Read more
Bergen: ForageBeef.ca gets a facelift
Research on the Record with Reynold Bergen
Canada’s National Beef Strategy has four goals that our industry aims to achieve by 2020. For the past year this column has explained how research is contributing to a 15 per cent increase in carcass cut-out value (the beef demand pillar), a 15 per cent improvement in production efficiency (productivity), and a seven per cent […] Read more
Persistence pays when it comes to forage breeding
Research on the Record with Reynold Bergen
Forage legumes provide high yields, protein and good animal performance while improving soil fertility by fixing nitrogen from the air. Alfalfa is the highest yielding and most widely used legume but can cause bloat. Legumes like cicer milkvetch, sainfoin and birdsfoot trefoil do not cause bloat. As little as 25 per cent sainfoin in a […] Read more
Exceptional forages for marginal lands
Research on the Record with Reynold Bergen
Tame forages often outperform native species in head-to-head comparisons under optimal growing conditions. This may not be the case on marginal land, with its tougher environments, poorer soil, rougher topography, harsher climates and precipitation extremes. Beef production is expected to rely more and more on marginal land, at least while returns from cash crops exceed […] Read more
What we’ve learned about castration in beef cattle
Research on the Record with Reynold Bergen
When Canada’s 2013 Code of Practice for the Care and Handling of Beef Cattle was being developed, some participants felt it should require pain control for castration at all ages, like the dairy code. The producers and researchers on the beef code committee were confident that pain control was beneficial for feedlot bulls and dairy […] Read more
Narrowing in on Johne’s Disease
Research on the Record with Reynold Bergen
Johne’s disease is caused by a bacterium (Mycobacterium avium paratuberculosis, or MAP) that was discovered in 1895 by a heavily bearded, bespectacled bacteriologist from Dresden named Heinrich Albert Johne. When a cow develops persistent, watery, smelly hosepipe diarrhea, and progressively loses weight and body condition, even though her appetite is normal and she isn’t running […] Read more
New Year’s resolution: Get better beef grades
Research on the Record with Reynold Bergen
Youthful carcasses from feedlot-finished cattle are graded for yield (amount of meat in the carcass) and quality (marbling score). Federal grading began during the Second World War to ensure quality standards during wartime price controls. Canada’s last major beef grading change occurred in the early 1990s, when Canada added quality grades to the grading system. […] Read more
