CYSTITIS and pyelonephritis is reported to account for between 7 and 29 per cent of adult sow deaths, although it has become less common in the UK in recent years. While clinically the condition must be treated on an individual basis, where a number of animals are affected the disease can affect farm performance. This article discusses the treatment of the individual sow and the various protocols for controlling cystitis in a herd.
