Inject to clean the womb?

摘要

An international exercise in datat gathering is taking place currently, to confirm scientific backing for a novel technique that is already in use in pioneering herds from Spain and France to Canada and the USA. It involves the injection of a prostaglandin product into sows at the end of farrowing -- a treatment which has been variously reported to reduce the interval to oestrus after the next weaning, increase the number of livebom pigs in the subsequent litter and cut both stillbirths and absortions.
