When it comes to the use of hormones in beef cattle, sometimes there are more questions than answers. Reynold Bergen, PhD, with the Beef Cattle Research Council (BCRC), breaks down why hormones are used and how they work in a recent BCRC webinar.
He tackles the question that is at the top of everyone’s mind – is the use of hormone implants safe? (Spoiler alert — yes!).
Although there has been sound scientific research to back up the decades-old practice of using hormonal growth implants, one can find many headlines to falsely suggest otherwise. It’s important to take a critical look at the source of such information. Is it credible? Do the studies reflect the science, real world conditions or practices? Who are the authors of the article and who performed the study? Continue reading
Allowing cattle access to clean water can improve herd health, as well as increase weight gain and backfat. A 2005 study reported that calves whose dams drank from water troughs gained on average 0.09 lbs per day more than calves whose dams had direct access to the dugout. Because water and forage intake are closely related, as cows drink more water they also spend more time eating and therefore produce more milk for their calves. Calves with access to clean pumped water were on average 18 lbs heavier at weaning time. A separate study in 2002 found that calves, with dams drinking clean water, gained 9% more weight than calves Continue reading
It will soon be time to start thinking about next year’s winter feed. If you plan to graze your cows on corn next fall or winter, consider these recommendations on planting corn for grazing purposes from Breeanna Kelln, a PhD student at the Western Beef Development Centre (WBDC) who also ranches near Duval, SK, and Dr. Bart Lardner, Senior Research Scientist at the WBDC:
1. First time? Start small
Corn is a high input crop. It requires more time and inputs at the beginning of the growing season than cereals used for grazing. Kelln says there is a learning curve for both the producer and the cattle, especially for cattle who have never been exposed to extended grazing. Lardner recommends Continue reading

Getting weaned calves on feed can be a challenge. This is often attributed to the change from a forage-based diet to unfamiliar feedlot rations and feed bunks, distress from recent weaning, illness, etc. To compensate for this, some feeders use a relatively high-energy receiving diet, the rationale being that if they’re not going to eat much, each mouthful better pack a nutritional punch. But part of the challenge these calves face may be complications from feed deprivation during marketing and transportation. Recent research led by the University of Saskatchewan’s Greg Penner suggests that the rations fed both before and after feed restriction affect how well cattle cope with and recover from these challenges (J. Anim. Sci. 91:4730-4738 and 91:4739-4749).
What they did: This study used Continue reading
Recognizing replacement and first calf heifers need extra management, producers take different paths to get to the same destination.
Beef producers like Darren Bevans in Alberta, Tyler Fulton in Manitoba and Murray Shaw in southwest Ontario know that replacement and first calf heifers need some extra attention, especially heading into and over winter — the heifers are not only pregnant and about to produce calves, but these young females are still growing themselves.
The “extra attention” doesn’t require over the top management, but just paying attention to feed and weather conditions to ensure heifers maintain a proper body condition to meet the nutritional requirements of the unborn calf as well as to support their own body growth.
In their respective operations, with extended fall and winter grazing programs, Bevans and Fulton manage heifers separate from their main cowherds so that Continue reading

Every time a beef producer in Canada markets an animal, he or she invests in research – through a portion of the Canadian Beef Cattle Check-off. Those producer dollars help fund scientific studies and innovative developments that are advancing Canadian beef production and impacting farms and ranches across the country.
What does that mean …for you, your herd and your industry?
The Beef Cattle Research Council (BCRC) is excited to invite you to an upcoming presentation to get a clearer picture of beef research in Canada.
Join us Thursday, August 17 at the BMO Centre in Calgary, Alberta. The BCRC presentation will be held in the Palomino Room A-C from 1:30 – 4:30pm.
You’ll hear recent examples of progress made, discuss the objectives to be tackled next, meet the individuals leading the way, and take home new ideas to help keep your operation ahead of the herd. Top researchers will be in attendance to discuss Continue reading

Aside from price insurance (in provinces where it is available), cow-calf producers can’t do much to control the price they receive for their calves, so managing input costs is often the biggest opportunity to improve profitability. The Western Beef Development Center has found that annual production costs differ by at least $100 per cow between the 25% lowest cost producers and the average producer. A 2015 Quebec report found a $79 per cow per year difference between a group of cow-calf operations with the highest margin and the average. In PEI, annual cost of production between the 10% highest and lowest cost operations differed by $660 per cow.
During BSE, drastic times called for drastic measures, and input costs were often cut as much as possible. But this may not be the best strategy for today’s more normal conditions. If it’s not done carefully, reducing inputs can harm profitability.
Feed is responsible for the biggest costs, including land, fuel, seed, and fertilizer to establish, grow, manage and graze or harvest pasture or winter feed. Investments to increase forage and feed yield and/or quality, through Continue reading

The rumen allows cattle to make highly nutritious beef out of things that humans can’t even digest. Rumen microbes have digestive enzymes that mammals don’t. This allows rumen microbes to break down complex feeds into very simple molecules, and reassemble those molecules into volatile fatty acids that the animal can absorb and use as an energy source. These microbes can also take some simple nitrogen-based compounds like ammonia and urea, turn them into amino acids, and assemble those amino acids into microbial proteins that the animal can digest and absorb. But the rumen can be wasteful as well. Some rumen microbes assemble carbon (C) and hydrogen (H) molecules together into methane (CH4) instead of volatile fatty acids. The animal can’t absorb or use methane, so methane gets belched out. This can waste significant feed energy – methane is the main ingredient in natural gas, after all. If we can find a way to reduce methane production in the rumen, we may be able to further improve feed efficiency and shrink beef’s environmental footprint at the same time.
