Other factors such as the species of livestock, their age, size, nutritional status and health will be important in determining how sick the animal becomes. Signs of Plant Poisoning When animals become sick suddenly for no apparent reason, especially if large numbers are involved or a new pasture is being used, plant poisoning should be suspected. Your local Agricultural office can help arrange plant identification, veterinary diagnosis and treatment. Animals suspected of being poisoned should be immediately removed from the suspect pasture. If the plants have been ingested quite recently, attempts to induce diarrhea to remove the toxins may be helpful.
Specific treatment depends on the quantity and type of plant that was eaten.
