Comparison of the Effectiveness of Two Different Pregnancy Detection Methods in Awassi Ewes
Aim of Study: This study aimed to compare several methods of pregnancy diagnosis in local Iraqi ewes including progesterone (P4) assay and the Ultrasongraphy (ULR) to identify the Sensitivty(Se), Specificity(Sp) and Accuracy(Acc) of the methods of diagnosis. Materials and Methods: This study was c...

| description | Aim of Study: This study aimed to compare several methods of pregnancy diagnosis in local Iraqi ewes including progesterone (P4) assay
and the Ultrasongraphy (ULR) to identify the Sensitivty(Se), Specificity(Sp) and Accuracy(Acc) of the methods of diagnosis. Materials
and Methods: This study was carried Sixty of local Iraqi ewes with 3-5 years old. The experimental animals were subjected to an estrus
synchronization. Blood samples were collected at 25 days of insemination, in order to measurement the level of P4 the first method. Pregnancy
was diagnosed with Transrectal ULR (TRU) (second method) via TRU and transabdominal (TAU) –ULR, respectively. Results: The result
showed that the Se, Sp, Acc of the P4 measurement at 25 days post-examination using the COBAS test were 95.1%, 42.1%, and 78.3%
with (P < 0.05), respectively. The Se, Sp, and Acc at 30 days of examination by ULR were 85.4%, 78.9%, and 83.3% respectively, with
(P < 0.05). The Se, Sp, and Acc at 60 days of examination by ultrasography were 100%, 100%, and 100% respectively, with (P < 0.05).
The findings demonstrated that Se and Acc for P4 assay in day 25 were higher than ULR at day 30, but the Sp was lower than ULR method.
Conclusion: It can be concluded that diagnosing pregnancy Depending on P4 assay at day 25 in sheep by measuring P4 concentration on day
25 after insemination and performing TR_ULR on day 30 and TA-ULR on day 60, are very effective methods for identifying pregnant sheep.
Furthermore, the parameters for evaluating these methods (Se, Sp, Acc) improved as the pregnancy progressed, reaching their maximum on
day 60 after insemination. |
