In raising livestock (or even pets and children) it's important to be aware of
which plants (and which parts thereof) are poisonous. Many people inquire
about buying sheep as "lawn mowers" or they put sheep (or other livestock)
on unimproved land that may harbor one or more of these dangerous plants. If
you intend to introduce animals to any area of your property, do a "nature
walk" and be sure to identify what plants are growing there (including trees
and shrubs) This is a partial list of plants compiled by Ag Agent Ken Bolton of
Jefferson County, Wisconsin for FARMING. The plants in green are ones I
have compiled from Dr. Henderson's book "The Veterinary Book for Sheep

What to do if your sheep ingest a poisonous plant:
One veterinarian advised the following for sheep who had eaten rhododendrons - 4 tablespoons Milk of Magnesia (laxative plus antacid); 1
teaspoon baking powder; 1 teaspoon powdered ginger. Dosage was 2 ounces given twice, 12 hours apart. Also advised was to give them
aspiring (3 per adult sheep)

IN AN EMERGENCY, administer charcoal from a firepit or fireplace to a poisoned sheep as soon as possible. There are charcoal products
formulated on the market for poison cases, but if you don't have anything available. just scoop up some charcoat and break it up into small
pieces and make the animal swallow it. I have a shepherdess friend who saved a ram from dying of cherry leaf poisoning by doing this.
