Identification of ferrous sulfate toxicity in a commercial broiler flock.
A 2.5% mortality rate was observed in a flock of 19,000 commercial one-day-old broiler chicks that had been placed 24 hours previously on litter treated with ferrous sulfate heptahydrate. Ulcerative ventriculitis and severe hepatopathy were the primary lesions observed grossly and microscopically. Pooled digesta contained 6854 ppm iron. Lesions identical to those found in the field case were reproduced experimentally.
