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
