Corn silage in backgrounding diets for cattle

Research on the Record with Reynold Bergen

Recent columns indicated that corn’s potential to produce 50 per cent higher silage (and starch) yields than barley may offset its 30 per cent higher growing costs, provided the right corn hybrid is selected for the local growing conditions, and provided growing conditions co-operate. The higher starch content of corn silage also means that feedlot […] Read more


Beef plants cannot operate efficiently without a steady supply of cattle from ranch to feedlot to plants.

Beef producers get a raw deal

Prime Cuts with Steve Kay

North America’s cattle producers were the first in the beef chain to be impacted by the spread of the COVID-19 virus from epidemic to pandemic. Yet they are getting a raw deal from their national governments in terms of financial or other aid. The Canadian and U.S. governments were quick to declare that meatpacking was […] Read more

Silage corn acres on the Prairies is on the rise.

Warm season crops and cool climates

Research on the Record with Reynold Bergen

According to Statistics Canada, silage corn acreage was 26 per cent higher in 2015-19 than in 2010-14. Most of this increase occurred in the Prairies. Achieving corn’s potential will depend on whether plant breeders can successfully adapt this warm-season plant to Canada’s cooler climate. Plants contain two kinds of carbohydrates. Non-structural carbohydrates are starches and […] Read more


For you to understand livestock nutrition, it’s important to have a firm grasp on basic math concepts as they relate to cattle feeding.

Math 101 for beef producers

Nutrition with John McKinnon

When I discuss various aspects of nutrition with producers, I often sense confusion when it comes to “as fed” versus “dry matter” (DM) conversions. Such conversions have a profound effect on our ability to predict feed intake and on our understanding of ration nutrient concentration, feed costs and on cost of gain calculations. If one […] Read more



How well do you mix your cattle feed?

Nutrition with John McKinnon

When it comes to putting quality feed in front of cattle, there are about as many ways to accomplish this task as there are cattle operations. In most finishing operations, we see total mixed rations (TMR) delivered via mixer wagons, while in cow-calf operations we see everything from pail-feeding grain and ad libitum bale feeding […] Read more

There are a number of steps producers can take to ensure that cattle maintain relatively high levels of feed intake while on high-grain rations.

Feed bunk management key to a sound feeding program

Nutrition with John McKinnon

In my last two columns, we have looked at issues with starting cattle on feed, as well as providing insight into the design of backgrounding and finishing programs. In this column, the focus will be on management of the feeding program, particularly feed bunk management. At its most basic level, feed bunk management is the […] Read more


University of Alberta researchers have flagged 19 genes that may play a role in feed efficiency. 


Cattle researchers map feed-efficiency genes

Research: News Roundup from the November 2019 issue of Canadian Cattlemen

After sifting through thousands of genes, researchers have flagged a handful of genes that seem to be related to feed efficiency in cattle. Hui-Zeng Sun, a post-doctoral student at the University of Alberta, used functional genomics and computational statistics to better understand feed efficiency, writes Justin Dupuis on the U of A’s research blog, folio.

The right mineral supplementation program can improve colostrum and calf immunity, according to a study on the University of Florida’s cow herds.

Research suggests trace mineral source matters

New research shows that organic trace mineral supplementation has benefits over its inorganic counterparts

When it comes to mineral supplementation for beef females, new research suggests that the source matters. Studies from the University of Florida show that organic trace mineral supplementation for cows has benefits compared to inorganic trace minerals in areas such as increased pregnancy rates, weaning weight and calf immunity. Dr. Matt Hersom is an associate […] Read more
