Are Texas bluebonnets poisonous to livestock - cattle, horses, goats, etc?

Plants in the genus Lupinus (Blue Bonnet), especially the seeds, can be toxic to humans and animals if ingested. Sensitivity to a toxin varies with a person’s age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plant’s different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil. I would not worry about livestock grazing on bluebonnets.
