Trans-Abdominal Ultrasonography during Second and Third Trimester in Murrah Buffaloes

Abstract

Ultrasonographic studies using trans-abdominal RI (1.39 ±0.18 to 0.66 ± 0.97) and PI (3.72 ± 0.65 to 1.17 ± 0.15)

Ultrasonography in Uterine Torsion: A Futuristic Tool

“…The declined pulsatility index (PI) and resistive index (RI) during the gestation were recorded in Murrah buffaloes, which may be due to gradual placental maturation, increased tertiary villi, and increased fetal blood flow and umbilical diameter (Singh et al, 2017). The researcher-clinician uses RI and PI to appreciate the vascular perfusion (Urban et al, 2007) because both RI and PI are not affected by either Doppler angle or blood vessel diameter but only by the heart rate (Maulik, 1993).…”

“…Additionally, mean pixel values measured by trans-abdominal ultrasonography were significantly higher (P<0.05) than the pixel values measured by trans-rectal ultrasonography in both normal and torsion suffered buffaloes. These observations could be useful to determine the duration and severity of uterine torsion The pixel values of Murrah buffaloes fetal fluid (40.44±1.19 to 36.72±2.33) measured in computer-based "Adobe Photoshop" software varied non-significantly during 4 th to 10 th month of gestation (Singh et al, 2017).…”

Transabdominal ultrasonographic determination of pregnancy and fetal viability in buffalo cows

“…A few and limited studies have adopted the transabdominal ultrasonography for evaluation of pregnancy in large ruminant (3,(13)(14)(15). While only one study was applicated the transabdominal ultrasonography for pregnancy diagnosis in buffaloes (16). The present study was designed to evaluate an alternative approach for pregnancy diagnosis and determination of fetal viability in Iraqi buffaloes.…”

Changes in blood flow to the umbilicus, placentomes, and uterus in Surti buffaloes during complete gestation

“…With the advent of ultrasonography maternal and fetal structures during gestation, fetal well-being and their correlations have been studied in live cattle ( [20] and buffaloes (Zambrano, 2015; Gaur and Purohit, 2018) [31] . The placentome diameters have formed the basis to predict gestational age in cattle (Blakenvoorde, 2011) and buffaloes (Singh et al, 2017) [35] . The placentome diameters increased linearly up to Day 180 of gestation but beyond Day 190 the placental dimensions decreased or remained static thereafter in cows (Adeyinka et al, 2014) [2] thus, limiting the prediction efficacy.…”
