Twelve sheep were exposed to sublethal doses of powdered metallic lead in their feed during the entire period of gestation and nine were treated as unexposed controls. The rate of lambing was 18% and 100% in the exposed and unexposed sheep, respectively. Abortions occurred at a rate of 27% in the exposed group but did not occur in the control group. Levels of lead in blood and urine of exposed sheep were related to the amount of lead in the feed. On the basis of this study it may be concluded that chronic lead poisoning in sheep causes abortion, miscarriages, and transitory sterility. 23 references, 3 figures, 3 tables.
