Relação entre comprimento craniocaudal e diâmetro da vesícula embrionária/fetal com idade de gestação por meio de avaliação ultra-sonográfica em ovino da raça Bergamácia

This study aimed to relate embryonic/fetal vesicle diameter (EVD) and crown-rump length (CRL) to gestational age in ewes from the 15th to the 45th day of pregnancy. Nineteen adult Bergamacia ewes with synchronized estrus were mated by the same male. Ultrasonographic evaluations were performed every 24 hours from the 15th to the 30th day after mating and every five days from the 30th to the 45th day using 5.0 and 7.5MHZ linear transducers. Average daily growth of EVD and CRL were 1.40mm and 1.33mm, respectively. The inverse calibration obtained for EVD was: Days = -11 + 50(0.1 + 0.04log EVD)1/2 with R2 = 0.85, and for CRL was: Days = 13.63 + 12.5(- 0.71 + 0.16CRL)1/2 with R2 = 0.93. Both EVD and CRL obtained by ultrasonography are useful measurements that allow the prediction of gestational age in Bergamacia ewes.

Profile of blood constituents during puerperium of ewes that had a caesarean section or a normal parturition.

Blood components of ewes submitted to cesarean section (n=21, GI) were compared to those with normal parturition (n=11, GII). Blood samples were taken at the following times: on delivery day, before delivery (T1), and one day (T2), two days (T3), three days (T4), and seven days (T5) after delivery. All animals showed normal erytrogram values, which could not be used as a prognostic guide of the pos-partum outcome. Immature neutrophil count in the leucogram was characteristic of animals that died due to surgery (GI). This study showed the importance of sequential hemograms for post-cesarean follow up. Despite of the immature neutrophil count be suggestive of cesarean effect, no determined hematological variable provided an accurate prognostic guide of cesarean section.
