The overriding economic importance of reproductive efficiency to successful pig production makes it necessary to collect and analyse performance records for the diagnosis and control of reproductive failure. Recently published production standards from the United Kingdom are related to the results obtained from 68 herds in the National Pig Health Scheme. It is concluded that more attention to the managerial aspects of weaning and rebreeding will do much to improve farrowing frequency.
