Abstract: The aim of the present investigation was to evaluate the different methods of early pregnancy diagnosis viz., Nonreturn rates, Salivary crystallization, Punyakoti test, Real-time B ultrasonography and Doppler echo+ and to compare between and among different methods. The present study was conducted on Large White Yorkshire aged between 2 to 3 years showing estrus signs and were bred. These were randomly divided and pregnancy diagnosis was carried out at an early stage from day 20 post insemination. Pregnancy diagnosis in Nonreturn rates was carried out using visual observations on day 21 post insemination with presence of boar in pregnant sows. Sows in Salivary crystallization were analyzed for early pregnancy with estimation of saliva progesterone concentration by different types of crystallization on day 18 post insemination using 400x microscope and were recorded in pregnant and nonpregnant sows, respectively. Pregnancy diagnosis in Punyakoti test was undertaken using seed xv germination inhibition test at day 26 post insemination and the sows diagnosed pregnant showed significant inhibition of seed germination and shoot length than the nonpregnant sows with a mean germination inhibition percentage (%) and shoot length (cm) of 74.66 ± 4.42 ; 3.33 ± 0.061 and 52.44 ± 2.33 ; 5.44 ± 0.92 in pregnant and nonpregnant sows, respectively. Sows in Real-time B mode ultrasonography were analyzed for early pregnancy using ultrasound at day 20, 25 and 30 post insemination. Pregnant sows showed anechoic embryonic vesicle within the echogenic uterus on day 20, expansion of embryonic vesicle and embryo proper in some sows on day 25 and clear visualization of anechoic embryonic vesicle and echogenic embryo proper in all pregnant sows on day 30 post insemination. Pregnancy diagnosis by Doppler echo+ were analysed using transabdominal transducer at day 30, 35 post insemination. Confirmation of pregnancy in all the sows that were selected in the five test groups was done by real-time B ultrasonography at day 45-60 post insemination. The overall diagnostic accuracy of Nonreturn rates, Salivary crystallization, Punyakoti test, Real-time ultrasonography and Doppler echo+ was 80.0, 75.00, 75.00, 100 and 85 per cent on days 21, 30, 26, 30 and 30-35 post insemination. The study concluded that Real-time transabdominal ultrasonography was 100 per cent accurate in diagnosing nonpregnancy. Among all the diagnostic techniques in the present study, transabdominal ultrasonography was more accurate in diagnosing pregnancy and nonpregnancy from day 25 post insemination.
