A field study into the appropriateness of transcutaneous ultrasonography in the diagnoses of uterine disorders in reproductively failed pigs.

This study was conducted to define the characteristics of the uterus of reproductively failed pigs by transcutaneous ultrasonography (SONO) in order to investigate the appropriateness of SONO to diagnose presumptive uterine disorders. Zearalenone (ZEA) is known to affect uterine function and causes endometrial liquid accumulation and was also determined. In 33 sows and 14 gilts, of unknown reproductive stages and culled for failing to conceive, the uterus was scanned transcutaneously and the females slaughtered on the same day or the day after scanning.
