Plan to Adapt When Grazing



Adaptive grazing herd management applies to grazing practices that are developed with careful consideration to the specific conditions that exist on individual farms and ranches. When it comes to adaptive grazing management, it’s all about using the resources you have available and incorporating different techniques depending on where you live, says rancher and consultant Sean McGrath. McGrath spoke about the value of being flexible but also the importance of making a plan and measuring success, during a BCRC webinar last winter.

Managing the movement of cattle through pastures or paddocks will help producers achieve energy efficiency. “Plants are solar panels and to make them efficient, we need to make sure there are solar panels there to start with,” McGrath said. He pointed out that it is much cheaper for cattle to graze than it is to manually feed them and understanding the key principles of grazing management is vital for adaptive management (skip ahead to 15:05).

Producers should manage herd movement to prevent overgrazing, which is defined as a plant being grazed before it has recovered from the previous grazing event. “We would never cut a hay field on the first of June and come back and hay it on June 10. A pasture is no different,” McGrath reasoned.

Adaptive Grazing Management and How it Can Increase Your Pasture Productivity Webinar: February 12



Adaptive grazing is a flexible grazing system that increases the productivity and performance of pastures. This system can benefit all types of operations and management intensities by mimicking the disruptive manner of natural grazing patterns through the use of grazing and rest periods.

DNA Sampling and Application in the Cow Herd

This is a guest post written by Sean McGrath, a rancher and consultant from Vermilion, AB.



DNA is the genetic code that determines how an animal grows, performs and interacts with its environment. Every animal inherits DNA from its parents with ½ coming from the maternal side and ½ from the sire. The building blocks of DNA are four base pairs: Adenine (A), Thymine (T), Guanine (G) and Cystosine (C). DNA is arranged in long ‘double strings’ in which A and T are paired and C and G are paired. A ‘gene’ is an area of this double string that codes for a specific function in the animal. By substituting one or more base pairs in the gene (i.e.: replacing an AT pair with a GC pair) a different function may be expressed in the animal (i.e.: red coat colour vs. black).

Technology to examine DNA in cattle has been around for several years, however in the past it has been cost prohibitive. Newer technology called SNP (pronounced “snip”) has changed much of this and made DNA testing a viable option for beef producers, even at commercial industry levels. SNP technology looks for Continue reading
