Blood samples taken from the ear vein of 1037 sows two to three weeks after service were assayed the same day using Ovucheck 'Sowside' kits. Colour development was compared with oestrous and pregnancy controls. Reliable data on reproductive performance were obtained from 908 sows sampled 17 to 20 days after service. The accuracy of identification of 796 pregnant and 12 non-pregnant sows was 94.6 per cent and 35.7 per cent, respectively. Excluding animals which returned outside the normal range of 18 to 24 days, 52.1 per cent of 48 empty sows were identified by the test. Problems with blood sampling were reported on seven of 18 farms and this may explain the low accuracy of the kit on some farms.
在配种后两到三周，从1037头母猪的耳静脉采集血样，并于当天使用Ovucheck“Sowside”试剂盒进行检测。将显色情况与发情和怀孕对照进行比较。从配种后17至20天采样的908头母猪中获得了关于繁殖性能的可靠数据。796头怀孕母猪和12头未怀孕母猪的识别准确率分别为94.6%和35.7%。排除返情时间超出18至24天正常范围的母猪后，该检测识别出了48头空怀母猪中的百分之52.1。在18个农场中的7个农场报告了采血问题，这可能解释了该试剂盒在一些农场准确率较低的原因。
