Poisonous Plants for Livestock in Kittitas County

Livestock have a remarkable ability to largely avoid poisonous plants. They learn about safe foods from their mother, and they have a variety of aversion mechanisms to avoid consuming the same toxic plant again following a negative experience, assuming they live. In addition, many toxic plants are quite unpalatable or distasteful. However, under certain circumstances, domestic animals will consume poisonous plants:

  1. When available or provided foodstuffs are undesirable
  2. When available forage is not sufficient to meet nutritional requirements for the individual
  3. When the toxic plant is at a particularly tasty stage of growth
  4. When insufficient water is provided forbs (weeds) may be selected to boost water intake
