Abstract
The study was undertaken with the objective to compare different techniques of
pregnancy diagnosis like pregnancy detector, vaginal electrical resistance (VER),
ultrasonography and progesterone assay in Osmanabadi goats. Pregnancy detector has not
yielded good results to detect pregnancy in does from day 1-30 post breeding. Higher
VER values are indicative to detect pregnancy on day 19 post breeding and with accuracy
of 66.67 % and 100 % from day 19-20 and day 21-30 post breeding respectively in does.
Trans-abdominal ultrasonography was effective tool to detect pregnancy with accuracy of
73.33 %, 80.00 % and 100 % from day 19-20, 21-30 and 31-45 post service respectively
in does. Visibility of embryonic vesicle and gestational sac as early as on day 20 after
natural service in does by trans-abdominal ultrasonography was an accurate, rapid, non
invasive, potential and safe technique for pregnancy diagnosis in does. Visibility of
gestational sac and fetal heart beat was detected on day 30 by trans-abdominal
ultrasonography and fetal heart beat and measurement of crown-rump length and
biparietal diameter measurement was possible on day 45 post breeding in does.
Progesterone estimation was useful aid to detect pregnancy in does with highest accuracy
(100.00%) from day 21-30 followed by day 19-20 (80.00 %) and day 1-18 (66.67 %)
respectively. Progesterone estimation on day 18 post breeding was a useful aid to detect
pregnancy in does. Progesterone estimation was effective aid to detect pregnancy from
day 1-18 post breeding in does with 81.82 % sensitivity, 25.00 % specificity and 66.67 %
accuracy respectively.
