title: Spontaneous acute poisoning by Crotalaria retusa in sheep and biological control of this plant with sheep.
abstract: After the diagnosis of acute Crotalaria retusa poisoning, 21 healthy sheep from the affected flock were returned to the paddock and continued to consume the sprouting plants. Two years after returning these sheep to the paddock, very few plants were still alive, and after 3 years, no C. retusa plants were observed. The sheep had neither clinical signs nor biochemical alterations and delivered healthy lambs. It is concluded that resistant sheep can be used for the biological control of C. retusa.
