Cattle and horses are most sensitive to the PAs, followed by pigs and chickens, and then sheep, goats and turkeys, which are the least sensitive to PA toxicity. Younger animals are typically more sensitive than adults. Therefore, the identification and control of groundsel in forages is important for preventing livestock PA poisonings.
