Like cattle performance, crop yields reflect the interplay between genetics, management practices and environmental conditions. Statistics Canada reports show that barley yields weren’t keeping up with other feed crops for decades. Barley yields increased 0.39 bushels/acre/year between 1980 and 2009, slower than either wheat (0.44) or corn (1.66). But since 2010, Canada’s barley yields have improved faster (1.32) than both wheat (0.84) and corn (0.66). This apparent tripling of barley yield gains is remarkable, especially considering that canola, corn and wheat development receive tremendous research investment, and their expanding acreages have squeezed barley’s shrinking acres onto less productive farmland.
Canada’s beef industry can share some credit for barley’s improved performance. Alberta Beef Producers, Alberta Cattle Feeders’ Association and the Beef Cattle Research Council have supported Alberta Agriculture’s Field Crop Development Center, where Dr. Flavio Capettini leads Canada’s only dedicated feed and forage barley breeding program. This team’s work under the 2013-18 Beef Science Cluster illustrates how much effort it takes to breed a new, improved feed grain variety. Continue reading →

10) Three Producers Share Ideas That Improve Efficiency
Beef producers across the country are always looking to improve management and production practices that not only benefit cattle, but also reduce their workload, and help to save time and money. This article highlights 3 producers and a recent change they have made to improve efficiency on their operations those changes include improved calf identification measures, installing remote cameras to monitor watering systems, and adopting quiet livestock handling practices in a flexible year-round grazing system.

Cattle breeders are often cautioned to avoid selecting too heavily for a single trait. Avoiding extremes is the obvious reason; selecting for small frame size in the 1950’s accidentally resulted in a dwarfism problem in a few breeds. Another reason is that a lot of traits are genetically correlated, meaning that selecting for one trait can have effects on other seemingly unrelated traits, like how selecting for increased growth rate or leanness eventually results in later puberty in heifers and larger mature cows. No matter what trait you’re selecting for, there will always be unintended consequences on other genetic traits. Breeding your way into a corner can happen quite quickly, but breeding your way out can take a lot longer.

The rumen allows cattle to digest fiber 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 fiber to protein.
There’s as much energy in straw as grain – burning a ton of either straw or grain generates the same amount of heat. But cattle can’t access all the energy in straw.
Grain is mostly starch. Starch is a long chain of identical sugar (glucose) molecules connected by simple links that rumen microbes can easily break using a few enzymes. That’s why feedlot cattle digest and convert grain-based diets so rapidly and efficiently. In contrast, straw contains cellulose, hemicellulose, pectin and lignin fibers. These contain many different molecules (not just glucose) connected by complex links that are much tougher (and require many more enzymes) for microbes to break. That’s why cows can’t be wintered on straw alone.
Fall has arrived and focus has shifted to winter feed supplies. Feed prices have dropped significantly from their June highs, but unfavorable weather conditions have left the question of available supplies. Hay prices vary significantly with prices in some areas with short supplies nearly double those in areas with adequate supplies. On the other hand, there could be numerous options for alternate winter feeds this year as some crops originally intended for grain are being harvested as livestock feed. Harvest delays and the likelihood of frost damage has led to quality downgrades. Alberta feed barley prices have dropped 13% from the June peak at $205/ton to $179/ton in September, and market analysts project that the feed grain markets have not hit bottom yet.
In eastern Canada, last year’s fall and winter conditions caused significant winter kill on the winter wheat and hay crops, while spring planting was delayed due to excessive moisture. According to local market reports, the fears of supply shortage have sent Ontario wheat straw prices to $0.06-0.10/lb in some areas compared to the historical range of $0.03-0.04/lb. Cool, wet weather in August and September are also causing harvest delays in the east, with the possibility of more cereal crops going to the feed market.
Do you ever look at a feed analysis report and think “huh?” Unsure of how to collect and send away feed samples for testing? Want to be sure you’re using feed wisely so your cattle perform as expected without wasting valuable feed? This webinar is for you.

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 →
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.
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 →
