A new webpage on BeefResearch.ca provides an overview of what mycotoxins are, the threat they represent for Canadian beef production and how to implement best practices to protect beef cattle.
Mycotoxins are often hidden hazards – a group of harmful toxins produced by certain types of fungi including mould that are only detectable with lab testing. They can create a variety of problems for beef cattle including reduced health and productivity.
The source of mycotoxins are fungi, including mould, that can be present in green pastures, cereal swaths, standing corn for winter grazing, cured and ensiled grass, cereal forages, crop co-products (straw, distillers grains, grain screenings, oilseed meals) and commercial feeds. Continue reading
Editors note: This article is the second in a series featuring ideas from beef producers across the country. See the first: Eight beef producers share their recent changes
Fine-tuned management decisions with quick results and bigger management changes that may take a few years for benefits to materialize — these are ideas that Canadian beef producers are applying to their farming and ranching operations.
Good ideas can range from improving pasture watering systems and regularly testing winter feeds, to reducing costs during the fall/winter grazing period, to simple ideas that reduce the stress of calving out heifers, to more sweeping approaches on how to manage an intensive grazing system — all have a common objective to improve beef herd performance in sustainable farming systems.
Here are some ideas that Canadian beef producers have shared that help them produce more pounds of beef, reduce workload, improve overall efficiency and benefit cattle and the environment: Continue reading
Do growth promoting, antimicrobial or other veterinary drugs affect the food safety of Canadian beef?
Veterinary drugs are regulated by the Food and Drugs Act and Regulations. All veterinary drugs go through a Health Canada approval process before they are licensed for use. The Health Canada Veterinary Drug Directorate (VDD) evaluates and monitors the safety, quality and effectiveness, and sets standards for the use of veterinary drugs to ensure that, when used according to label directions, they are safe for both animals and humans.
For a more detailed explanation of the veterinary drug approval process in Canada, download ‘Canada’s Veterinary Drug Approval Process‘
Label and veterinary directions indicate proper administration doses and routes for veterinary products, as well as pre-slaughter withdrawal times, which ensure that the product has been metabolized by the animal before the meat is harvested. Most drugs are completely metabolized during the prescribed minimum number of days between the last administration of the drug and slaughter, and therefore leave no residue. Continue reading
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
This article written by Dr. Reynold Bergen, BCRC Science Director, originally appeared in the October 23, 2017 issue of Canadian Cattlemen magazine and is reprinted on the BCRC Blog with permission of the publisher.
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
