In addition, it aimed to study the concentrations of cortisol and the echotexture of the placentome. Fourteen goats were assigned into two equal groups (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20097, each) based on the animal\u2019s emotional temperament (calm versus nervous groups). All goats were examined for assessment of the blood flow within the fetal aorta (FA), umbilical artery (UMA), and middle uterine artery (MUA) using color-pulsed Doppler ultrasonography. Goats were exposed to light sedation using the recommended dose of xylazine (0.05\u00a0mg\/Kg Bw) intramuscularly. Goats in each group were reassessed for the studied parameters after sedation. Blood samples were drawn to determine the concentrations of cortisol. Placentome echotexture pixel intensity (PXI) was evaluated using computer image analysis software. Results revealed the significant impact of the xylazine sedation on the Doppler indices of the blood flow within the measured arteries (FA, UMA, and MUA), the PXI of placentome echotexture, and cortisol concentrations. The emotional temperament of goats had significant effects on the blood flow parameters of the MUA and UMA, concentrations of cortisol, and the PXI of the placentome. The interaction effect (sedation x temperament) was noticed in the measured parameters of the UMA blood flow, fetal heart rate, and cortisol concentrations. In conclusion, xylazine sedation and emotional temperaments induced alterations in the echotexture of the placentomes as well as the hemodynamic parameters of late-stage pregnant goats without affecting the pregnancy outcomes.\n                  <\/jats:p>","DOI":"10.1007\/s11259-024-10330-2","type":"journal-article","created":{"date-parts":[[2024,2,20]],"date-time":"2024-02-20T22:02:06Z","timestamp":1708466526000},"page":"1545-1561","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Emotional temperaments in advanced pregnant goats and its relationship with the feto-maternal blood flow and placentome echotexture"],"prefix":"10.1007","volume":"48","author":[{"given":"Haney","family":"Samir","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayman A.","family":"Swelum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Farag","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hossam R.","family":"El-Sherbiny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,2,21]]},"reference":[{"issue":"3","key":"10330_CR1","doi-asserted-by":"publisher","first-page":"H881","DOI":"10.1152\/ajpheart.00611.2009","volume":"298","author":"GW Aberdeen","year":"2010","unstructured":"Aberdeen GW, Baschat AA, Harman CR, Weiner CP, Langenberg PW, Pepe GJ, Albrecht ED (2010) Uterine and fetal blood flow indexes and fetal growth assessment after chronic estrogen suppression in the second half of baboon pregnancy.
