Livestock can be poisoned or injured by certain plants while grazing. One of the most important steps in reducing animal suffering or loss is good pasture management. Keeping the desirable forage species producing throughout the grazing season reduces the possibility of animals grazing toxic weeds.
Toxic plants (e.g., Creeping Indigo, Crotalaria, black nightshade, spiny pigweed, lantana, etc.) are commonly found throughout Florida. Though animals do not usually choose to graze toxic plants when forage is abundant, they may ingest toxic weeds when quality forage is limited due to poor growing conditions or over-grazing.
If symptoms of poisoning should occur, it is recommended that you call your veterinarian as soon as possible.
