You’ve got questions and I’ve got answers.
This week I’m continuing my quest to make myself obsolete by sharing more information on my method for teaching livestock to eat weeds. My dream is that teaching livestock to eat weeds will become such a common practice that my name as the developer of the technique will be forgotten. I’m waiting to pop the champagne cork to celebrate that event, something I had hoped would happen in 2024. I may not make it by 2024, but maybe it can still happen. So read on for answers to questions I’ve been asked about the particulars of livestock as weed-eaters.
(And if you missed them, here is the first article collection in the series covering examples of weeds that make great forage and why we should graze them, and here is the second collection on the science behind why this works.)
How Much More Forage Will I Have If My Livestock Are Weed-Eaters?
For the answer to this question, I worked with a economist who looked at the literature on how may weeds the typical pasture has, and what that meant when converted into usable forage. The answer: 43% more forage.
Another answer: 200,000 more cows a year in a 17-state region.
In 2010, a rangeland ecologist working for the Agriculture Research Service (ARS) developed an online calculator that could tell producers how many more cattle they could raise if they were able to eliminate one or two widespread invasive plants. He used it to estimate that ranchers in a 17-state region could raise 200,000 more cows a year and save tens of millions of dollars if leafy spurge were eliminated. Check out what he learned and how we can help him accomplish that dream – by teaching livestock to eat those weeds.
Will my livestock gain as much weight eating weeds?
Yes, and maybe even more. This article talks about the nutritional value of weeds and why they’re good for weight gain.
How Should I Graze to Best Manage Weeds?
You need to know some things about your weed so you can choose the right timing and grazing intensity. In general, since they come up earlier than many of our “preferred” forages, hitting them early can slow them down and give your grasses and other forages a competitive advantage. Another great time to hit them is just as they’re beginning to flower. This reduces seed set and how many weeds you’ll have to manage in coming years.
Here’s a free ebook I put together on how to manage grazing for three weeds: Canada thistle, leafy spurge, and spotted knapweed. Even if these aren’t your weeds, it will give you an example of what you need to know and how to adjust your grazing.
