Animals can then adapt to higher levels. Do not feed suspect materials to hungry animals. Severely restrict or stop intake of suspect materials if problems are encountered. In dry years, most poisoning most often occurs in overgrazed pastures. Check your pastures for toxic plants.
Pastures are subject to many potentially harmful toxic plants.
Exposure can come through weedy pastures, hay, along ditches, in wooded areas, in corrals and holding lots. Signs of poisoning may include chronic wasting disease, abortions, congenital defects, and death. Ferns, night shade, crotalaria, oleander, sicklepod, horsenettle and many other plants, which stay green in a drought have toxic components. The following is a listing by class of poisoning. Fungi known as ergot are common in the seed heads of warm season grasses such as Dallisgrass and Bahia grass.
