Abstract The study was conducted to evaluate body temperature of hair sheep ewes at various stages of the production cycle in an accelerated lambing system in the tropics. Multiparous St. Croix White (STX: n = 7) and Dorper x STX (DRPX; n = 7) ewes lambing in October and raising single lambs weaned at 120 d were used. Synchronized breeding began at 96 d postpartum. Vaginal temperature (VT) was measured at 10-min intervals for 96 h at 38 and 66 d post-partum (PP1, PP2) and at 2 days after mating (PM) using data loggers. Daily minimum, maximum and range of VT were determined for ewes within PP1, PP2 and PB. Data were analyzed using GLM procedures of SAS with breed, day and time (PP1, PP2, PM) in the model. Mean ambient temperature, temperature-humidity index and solar radiation at PP1, PP2 and PM were 24.8 °C, 25.2 °C, 23.8 °C, and 74.7, 74.9, 73.3, and 180 W/m2, 160 W/m2 and 155 W/m2, respectively. Minimum VT was lower (P < 0.002) in STX than DRPX ewes at PP1, PP2 but not PM (38.27 ± 0.04 vs 38.44 ± 0.04 °C, 38.16 ± 0.04 vs 38.33 ± 0.04 °C, 38.47 ± 0.04 vs 38.58 ± 0.04 °C, respectively). There was no difference in maximum VT between breed or time (P > 01.0). There was no breed difference (P > 0.10) in range of VT, but the range of VT was lower (P < 0.0001) at PM compared to PP1 and PP2 (1.22 ± 0.04 vs 1.77 ± 0.04 vs 1.63 ± 0.04 °C, respectively). These results show that tropically adapted STX ewes have lower body temperatures, as shown by the lower minimal VT which indicates a degree of nighttime cooling, during the postpartum period compared to DRPX ewes in a tropical environment.

Uterine Involution

The aim of this study was to observe the uterine involution of Etawa crossbreed (PE) goat using transcutaneous ultrasonography (USG). This study used four postpartum female goats that released placenta normally. The goats were examined on lateral recumbence position. Uterine involution was observed daily. The study began from the first day of postpartum period until there were no more reduction of uterine horns lumen diameter. From the 1st to 7th day of postpartum period, ultrasound imaging of the uterine wall showed caruncle which was hypoechoic, lumen of uterine filled with lochia (the image was hypoechoic to anechoic) and a clearly visible uterine horns lumen which had decreased in diameter from 105.9 ± 0.9 mm to 87.2 ± 4.6 mm. From the 8th day to the 14th day, lumen diameter had decreased from 80.4 ± 3.8 mm to 63.6 ± 3.2 mm. The presence of caruncle was reduced and the amount of lochia was decreased (anechoic). From the 15th day to the 21st day, lumen diameter had decreased from 61.4 ± 2.1 mm to 52.1 ± 2.7 mm, and the remnants of caruncle and lochia were still visible. From the 22nd day to the 26th day, the diameter of the uterine wall had decreased from 49.7 ± 0.6 mm to 41.5 ± 6.7 mm, and the lochia and caruncle were no longer visible. From the 26th to the 30th day, uterine horns lumen diameter had still decreased from 41.5 ± 6.7 mm to 31.7 ± 0.9 mm. Uterine horns lumen diameter size had decreased every day, stabilized on the 30th day, and ceased to decrease on the 31st day, where the diameter size was the same as on the 30th day postpartum (31.7 ± 0.9 mm). It can be concluded that the duration of uterine involution in PE goats, which had normal delivery is 30-31 days.

Follicular Dynamics

The study of ovarian follicular dynamics (OFD) and other changes in the bovine reproductive tract has developedsignificantly over the past two decades, primarily due to the use of non-invasive investigative approaches suchas ultrasound. Advances in ultrasound examinations have provided a better understanding of ovarian activity,uterine involution, oviducts status, and other segments of the reproductive tract in the bovine postpartumperiod. Procedures including tracking of the reproductive tract have likewise aided in the development of newmethodologies and techniques to improve reproductive performance in cattle. The aim of this review was tosummarize knowledge regarding the reproductive tract in dairy cows during the postpartum period.

Purpose Our aim was to describe the changes observed by ultrasonography in uterine dimensions during the early puerperium among women who experienced an uncomplicated puerperium. Additionally, the influence of parity, mode of delivery, breastfeeding and birth weight on uterine involution was evaluated. Methods Ninety-one patients underwent an ultrasound examination on days 1 (D1), 2 (D2) and 7 (D7) of the postpartum period. The longitudinal, anteroposterior and transverse uterine diameters were measured, and the uterine volume was calculated by the formula: longitudinal diameter (LD) X anteroposterior diameter (APD) X transverse diameter (TD) X 0.45. The thickness and length of the uterine cavity were also measured. Results The uterine volume and the LD, APD and TD decreased by 44.8%, 20.9%, 11.8% and 20.0% respectively. The uterine cavity thickness was reduced by 23%, and the length of the cavity was reduced by 27.2% on D7. Uterine involution was correlated inversely with parity when the day of the postpartum period was not taken into account (p = 0.01). However, when the uterine involution was correlated to parity separately, with D1, D2 or D3, no correlations were found. A significant difference occurred at D2, when it was found that the uterus had a smaller volume following cesarean section compared with vaginal delivery (p = 0.04). The high birth weight and breastfeeding were significantly related to uterine involution (p ≤ 0.01 and p = 0.04). Conclusion The sonographic evaluation of the uterus in the early puerperium should consider birth weight, breastfeeding and parity, as well as the delivery route on D2, to identify abnormalities related to uterine involution.
