Cows can control Canada thistle and brush

Managed grazing is one way to suppress aspen and thistles in your pasture

By
Last fall, while driving through central Alberta and Saskatchewan, I saw pasture after pasture full of mature Canada thistle and aspen regrowth, which reduce available forage. Over the years, research has found that rotational grazing can help control these weedy outbreaks. The main reason for rotational grazing is to give plants a chance to regrow […] Read more

Nature vs. Nurture in animal performance

Research on the Record with Reynold Bergen

By
Nothing is ever as simple as we think it is or wish it was. We’ve known for centuries that an animal’s performance, health, behaviour and other traits depend on a combination of their genetics and their environment. The genetics are inherited from their parents. Environmental influences are not inherited. Environments might be similar across generations […] Read more
University of Alberta researchers have flagged 19 genes that may play a role in feed efficiency.

Cattle researchers map feed-efficiency genes

Research: News Roundup from the November 2019 issue of Canadian Cattlemen

By
After sifting through thousands of genes, researchers have flagged a handful of genes that seem to be related to feed efficiency in cattle. Hui-Zeng Sun, a post-doctoral student at the University of Alberta, used functional genomics and computational statistics to better understand feed efficiency, writes Justin Dupuis on the U of A’s research blog, folio.

University’s ‘Beefier Barley’ billboard binned

By
A billboard about Alberta barley’s prospects under climate change in the University of Alberta’s ‘Truth Matters’ promotion — a series of ads meant to spark discussion about its researchers’ work — has been winnowed out of the campaign. Jacqui Tam, the Edmonton-based U of A’s vice-president for university relations, announced Sunday it would withdraw the […] Read more

Could a new premium program and grading system boost consumer satisfaction?


A student project at the University of Alberta suggests that introducing an additional quality grading system could benefit the Canadian beef industry. Five animal science students in the final year of their undergraduate degree have proposed the development of a voluntary muscle-based grading system, modeled after a similar program that has had positive results in […] Read more

Genomic tools for crossbred cattle in the works

The structure of the beef industry poses challenges

By
Genomic technologies may soon be available to predict traits in commercial cattle, according to University of Alberta researchers. Graham Plastow, CEO of the University of Alberta’s Livestock Gentec Centre, spoke about current opportunities for commercial producers to benefit from genomic tools and technologies in development during the Canadian Beef Breeds Council’s Technical Forum. This was […] Read more

That sort of sums up Brian Chrisp’s view on rearing purebred cattle

By
When Brian Chrisp went to college with plans of becoming a veterinarian, he didn’t think he would ever want to come back to the family farm near Vermilion, Alta. But life intervened. “While I was in college I switched course and got an ag economics degree at the University of Alberta. As graduation neared, I […] Read more

Do RFI ratings predict cattle performance on pasture?

In a word, no

By
Producers often wonder if genetic markers for feed efficiency based on drylot tests reflect feed efficiency on pasture where terrain, water sources and plant diversity are very different from a pen setting. Genetic markers for residual feed intake (RFI) have been identified that correlate well with actual RFI determined during the standard trials in pens […] Read more
