Horse owners and other livestock owners should be aware of what plants can kill their animals. For example did you know that just one leaf of an oleander plant can kill a horse in a matter of hours? Yet most unaware horse owners have those plants growing as ornamental bushes in their landscape. I have a friend that almost went ballistic when a neighbor or hers trimmed his oleander bushes and threw the trimmings into her pasture. Her neighbor certainly got educated later that day by her and her husband the deputy sheriff.
If you own livestock, you must educate yourself to the dangers of poisonous plants that your animals might come in contact with. Get yourself a good book on plants with lots and lots of full color photos like, All About Poisonous Plants Most feed stores have them and of course you can find them on sale all over the internet. Or just click on the link above.
Livestock owners that feed their animals baled hays should also be able to identify poisonous plants that have been dried and baled in their hay. Some plants are harmless at certain stages of their growth so you need to be aware of the plants poisonous life cycle.
Protect your animals and get educated about poisonous plants.
