Early and accurate determination of pregnancy is critical to optimum reproductive performance in pigs and enables farmers
to early rebreed or cull non-pregnant animals. Most of the conventional diagnostic methods are unsuitable for systematic
application under practical conditions. The advent of real-time ultrasonography has made it possible to establish relatively
more reliable pregnancy diagnosis. The present study was carried out to evaluate the diagnostic accuracy and effectiveness of
trans-abdominal real-time ultrasound (RTU) imaging vis-à-vis pregnancy status in sows reared under intensive management.
Trans-abdominal ultrasonographic examinations were performed using a mechanical sector array transducer and portable
ultrasound system in crossbred sows from 20 days post-insemination for up to next 40 days. Animals were followed up for
subsequent reproductive performance with farrowing data used as the definitive test for deriving predictive values. Accuracy
for diagnosis was determined by diagnostic accuracy measures like sensitivity, specificity, predictive values, and likelihood
ratios. Before 30 days of breeding, RTU imaging had 84.21% sensitivity and 75% specificity. Relatively higher false diagnosis
rates were obtained in animals checked at or before 55 days after AI than in animals checked after 55 days (21.73% versus
9.09%). Negative pregnancy rate was low with 29.16% (7/24) false positives. Overall sensitivity and specificity, using farrowing
history as the gold standard, were 94.74% and 70.83% respectively. The sensitivity of testing tended to be slightly
lower in sows with litter size of less than 8 total born piglets, compared to sows with 8 or more piglets. Overall positive
likelihood ratio was 3.25 while negative likelihood ratio was 0.07. The results indicate that pregnancy in swine herds can be
reliably detected earlier in gestation by 30 days post-insemination using trans-abdominal RTU imaging. This non-invasive
technique with portable imaging system can be used as an integral part of reproductive monitoring and sound management
practices for profitable swine production systems.
