Do antimicrobial growth promoters really improve performance, or just improve health?

CCT150518Ionophores (Rumensin, Bovatec, Posistac) are not medically important because the ionophores approved for use in cattle are not used in human medicine. Other antimicrobials used in livestock are medically important. Concerns around antimicrobial resistance in both human and veterinary medicine have led to increased scrutiny regarding how medically important antimicrobials are used in livestock production. In response, pharmaceutical companies throughout North America are removing production claims (i.e. growth and feed efficiency) from products containing medically important antimicrobials. Some of these products also have health claims, but four Canadian products only have production claims (two Aureo S-700G products, Chlor S-700, and Neo-Terramycin). These products may disappear unless the companies pursue new health-related label claims.

But do medically important antimicrobials really promote growth? Or do they just keep calves healthy, which grow better than sick calves? Alberta Agriculture and Rural Development’s Dr. Kim Stanford led a research project Continue reading

Weed Control

Weed control is an important aspect in forage and cattle production as it affects forage yield and quality. Weed management can be accomplished through cultural, mechanical, chemical and biological controls. A more effective and sustainable weed management program should integrate two or more of these methods and consider long-term impacts. Over 95% of the weed control in a healthy forage crop comes from the competition provided by the existing forage stand.

Weeds on farmed landWeeds in perennial Alberta crops

In 2009, a survey that focused on weeds was conducted of common irrigated crops including annual cereals (spring wheat, barley, corn), annual broad-leaved crops (canola, sugar beets, dry beans, potatoes) and perennial crops (alfalfa, grass hay) in Alberta. For the 135 fields of irrigated perennial crops, the top 10 most abundant weeds were reported as: Dandelion, Canada thistle, Lamb’s-quarters, Kochia, Green foxtail, Wild buckwheat, Redroot pigweed, Foxtail barley, Smooth brome, and Quack grass.

Weeds on pasture

Other than plants that are poisonous to livestock, individual plants growing on a pasture are rarely a problem. However when large populations of a single species spread over a wide area, choking out and replacing the pasture grasses that provide nutrition to livestock, weeds become an economic issue.1

If weeds become a problem, they can compete or interfere for light, nutrients, water and space, directly influencing forage yield. A study by Chad and Bork (2004)2 assessed…

ABP and ALMA accepting applications for forage research funding

Attention researchers:

The Alberta Beef Producers (ABP) and the Alberta Livestock and Meat Agency (ALMA) are now accepting letters of intent (LOIs) for research and development in areas that address targeted industry priorities.

As stated by ABP “The purpose of this $1 million targeted call for proposals is to focus on forage research priority areas benefiting Alberta’s cattle producers. Forage is the key driver of Alberta’s cattle industry competitiveness, accounting for two-thirds of costs.”

Only LOIs related to the following targeted priority research areas will be considered: Continue reading

The Value of Your Industry Investments in Research

This article written by Andrea Brocklebank, BCRC Executive Director, originally appeared in the April 2015 issue of Saskatchewan Cattlemen’s Connection magazine and is reprinted on the BCRC Blog with permission of the publisher.

“Telling the future by looking at the past….is like driving a car by looking in the rear-view mirror” – Herb Bordy…but history helps illuminate the present. Shortly after Confederation, agriculture became a nation-building tool to settle the West and prevent U.S. expansion. Agriculture provided freight for Canada’s railroads, fed the urban population, and supplied millers, processors and exporters. Canada’s Experimental Farms Stations Act of 1886 supported productivity-boosting research and provided even more freight, food, and economic spin-offs.

Canada’s farm population declined as technology and mechanization reduced the need for farm labour, and more people moved into other jobs in Canada’s expanding economy. When Canada’s first agricultural census was completed in 1931, 31.7% of Canada’s population Continue reading
