One of the first steps to consider when choosing an implant is deciding on how aggressive you want to be with your program.

Choosing the right implant for feedlot cattle

Nutrition with John McKinnon

In last month’s column, I covered the various classes of implants currently on the market and traced the development of the technology over the last 50 years or so. With this column, I want to look at some of the factors to consider when choosing an implant for feedlot cattle, with emphasis on the class […] Read more

There are a variety of things to consider when feeding set-aside cattle.

Flattening the cattle supply curve

Nutrition with John McKinnon

Over the last 10 weeks or so that we have lived through the COVID-19 pandemic, we have come to understand the term “flattening the curve” and its importance to our public health system. With respect to the beef industry, the largest impact of the virus to date has been on the health and safety of […] Read more

Meeting metabolizable protein requirements of your cattle

Nutrition with John McKinnon

In my April column, I covered the basic concepts of ruminant protein nutrition and introduced the concept of metabolizable protein. As a quick review, metabolizable protein is the protein — or more specifically the amino acids — available for absorption in the small intestine of the animal. Metabolizable protein is used to meet the animal’s […] Read more

It’s important to realize that an animal does not require “protein” per se. Rather, it requires amino acids, the building blocks of the various proteins.

The basics of protein nutrition for improved cattle performance

Meeting the protein requirements of your cattle is a cornerstone of a well-balanced nutrition program. Not only is protein one of the most expensive nutrients to supplement, but it is also one of the most important from a performance perspective. Consider, for example, that protein requirements increase during the latter stages of pregnancy and with […] 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?

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
