Researchers at Embrapa and the Universidade Federal Fluminense have developed a new treatment for pseudopregnancy in goats and ewes, a condition that can cause subfertility and infertility. The treatment involves using three doses of the hormone prostaglandin with a ten-day interval between doses. The study, sponsored by the National Council for Scientific and Technological Development (CNPq), has shown initial success and the treatment is already being used in the field. The researchers recommend periodic ultrasound evaluation of herds to identify the condition early and minimize economic losses. The treatment drains uterine fluid and stimulates ovulation, with recovered females usually maintaining good reproduction rates. However, females with undrained uterus should be discarded after subsequent attempts.
