This week’s article collection was inspired by an email I got from the Agricultural Research Service presenting the results of some research looking at foraging behavior in rotational and continuously grazed pastures and how that affects weight gain. The results are part of ongoing, long-term, landscape-scale research at the Central Plains Experimental Range.
The first three articles in this collection will likely cause some consternation as their results are different than what both researchers and graziers expected. Having shared some of these articles in the past, I know folks will say, “Well! They must have done something wrong!”
My response to that is: This is science and the point of it is to provide information that might be helpful in improving things for everyone. To that end, these researchers clearly tell you everything they did that led to these results. If you see an error, the next step in science is to do research with your own adjustments, and see what the answer is. In that way, we all move forward. In the meantime, we can consider this new information and if it leads us to reconsider what we “know” and what we might do differently.
I’ll also add a word on continuous grazing. Like all management, doing it well means knowing how much forage you have, how much you need, and then stocking accordingly. When we get in trouble is when our stocking rate doesn’t match the forage available.
First, the New Paper
Here we learn how grazing management affects foraging behavior and how much weight animals gain.
Two Papers That Add to Our Knowledge
Yes, regrazing is bad. But is it really happening to the extent we think it is? These researchers crawled around on the ground marking tiny grass plants and then coming back to what happened.
After working really hard to make good rotational grazing decisions, this 11-stakeholder group of ranchers, and land managers learned something surprising.
Thoughts About the Economic and Lifestyle Considerations When Deciding How Often to Move Livestock
John Marble has done a lot of thinking about this and his grazing business has changed over the years based on what he’s discovered and on how he prefers to spend his time. I think you’ll appreciate his ideas.
