Abstract
Aim:
This study was aimed to evaluate the sensitivity, specificity,
predictive value and accuracy of ultrasonography in pregnancy rate
(PR) prediction in Sahelian goats after progesterone impregnated
sponge synchronization within the framework of caprine artificial
insemination (AI) program in Fatick (Senegal).
Materials and Methods: Of 193 candidate goats in AI program,
167 were selected (day 50) in six villages. Estrus was
synchronized by progesterone impregnated sponges installed for 11
days. Two days before the time of sponge removal (day 4), each
goat was treated with 500 IU of equine chorionic gonadotropin and
50 μg of dcloprostenol. All goats were inseminated (day 0) with
alpine goat semen from France at 45±3 h after sponge removal (day
2). Real-time B-mode ultrasonography was performed at day 50, day
13, day 0, day 40 and day 60 post-AI.
Results: Selection rate, estrus response rate, AI rate, PR at
days 40 and days 60 were 86.53%; 71.85%; 83.34%; 51% and 68%
(p<0.05) respectively. Value of sensitivity, specificity, positive
and negative predictive value, accuracy, total conformity,
conformity of correct positive, conformity of correct negative and
discordance of pregnancy diagnosis by trans-abdominal
ultrasonography (TU) were 98.03%; 63.26%; 73.52%; 3.12%; 81%; 81%;
50%; 31% and 19%, respectively.
Conclusion: These results indicate that the TU can be
performed in goats under traditional condition and emphasized the
importance of re-examination of goats with negative or doubtful TU
diagnoses performed at day 40 post-AI.
Keywords: accuracy, artificial insemination, estrus,
pregnancy, Sahelian goats, ultrasonography.
