Answer 1

The main reason for livestock poisoning from plants is overgrazing in a specific area. When livestock are confined to a limited pasture or range and there is inadequate vegetative cover or variety of plants, they tend to eat whatever is available, including potentially toxic plants. Overgrazing causes a depletion of the preferred and nutritious forage plants, leaving behind less desirable and potentially toxic plants for the livestock to consume. This increases the risk of livestock consuming poisonous plants, leading to poisoning.
