The Canadian Beef Industry Award for Outstanding Research and Innovation is presented by the Beef Cattle Research Council (BCRC) each year to recognize a researcher or scientist whose work has contributed to advancements in the competitiveness and sustainability of the Canadian beef industry.
Nominations are welcome from all industry stakeholders. Download the nomination form here. Nominations must be submitted firstname.lastname@example.org no later than May 1st with 3 or more letters of support that speak to the nominee’s influence on Canada’s beef industry.

Growth promotants dramatically improve the growth rates and feed efficiency of beef cattle. Trenbolone acetate (TBA) behaves like testosterone and is used in several feedlot implants (Component, Revalor, and Synovex). Melengestrol acetate (MGA) behaves like progesterone, a pregnancy hormone. Some feedlots feed MGA to suppress estrous cycles and riding activity in heifers until a few days before slaughter. Ractopamine (Actogain, Optaflexx) is a feed additive that improves weight gain, feed efficiency and leanness in the last 28-42 days before slaughter.
Growth promotants also have environmental benefits; reducing the number of days (and amount of feed) needed to finish cattle means fewer days producing greenhouse gases and manure, and less water, feed and fossil fuel inputs per pound of beef.
Animals metabolize and excrete these growth promotants over time – that’s why growth promotant residues in beef are too low to pose any risk to consumers. But do these excreted residues and metabolites pose a risk to the environment? How long do they persist in soil and manure, and is there a risk they could enter surface or groundwater?
This past year we published 78 blog posts that offered production tips and decision tools, provided a science-based perspective on issues in the media, highlighted new beef, cattle and forage research projects and results, and announced other exciting initiatives. Of those, these were the top 10 most popular:
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.
