1. Know your plant.

Begin by finding out about the nutritional value and the toxins in your target plant. Many weeds are very nutritious, but like all plants they contain toxins. Prevent illness by knowing your toxins. 2. Choose the right animals to train.

Young animals are more likely to try new things, females stay in the herd longer and teach their offspring. Train only as many as you can handle. They will teach everyone else for you. 3. Reduce the fear of new foods

Setting up a daily routine of feeding animals something nutritious but unfamiliar gives them positive experiences with new foods and makes them comfortable trying new foods. Feed them something new twice a day for four days. When you introduce your target weed on the fifth day, they'll eat it because it's just one more new thing in their routine of new things. 4. Practice in pasture.

Each new plant requires that your animal learns a new grazing technique. Give them a day or two to practice in small "classroom" size pastures. Then when you send them out in the world, they'll have the skills they need.
