New Publication-Toxic Plants in Midwest Pastures and Forages

New from the Learning StoreToxic Plants in Midwest Pastures and Forages

While most plants are safe for livestock to consume, a few plant species can sicken or even kill animals if ingested. Recognizing poisonous plants and knowing proper livestock management are important steps in minimizing the potential for poisoning animals.

There is a new guide to identification information about plants, the guide provides detailed information on what the toxin is, what animal species it is toxic to, where the plant is generally found, what parts of the plant are toxic and how long the toxin persists, and what can be done.

The easy to use, spiral-bound book, Toxic Plants in Midwest Pastures and Forages, is available online at The Learning Store under Farming/Crops/Forages & Pastures/Diseases/Weeds, Insects and Other Problems. The guide can either be downloaded for free or a hard-copy purchased.

If you suspect plant poisoning in livestock, follow these recommendations:
• Remove animals from where the plants are present and remove any affected feed or forage
• Contact your veterinarian
• Survey the area to identify any plants that may be the potential source of toxicity.
Use a digital camera to compare the images to online identification databases such as or published references.

You can also submit unknown images to your county extension agent to confirm their identity or if you cannot reach your county agent, contact Mark Renz, UW-Extension Weed Scientist, by phone at 608-263-7437, or email at
