Objective: To characterize ultrasound images of placenta and amniotic fluid in cases of singleton pregnancies beyond term predictions, and also explore the relationship between placenta, amniotic fluid and labor transfer status, postpartum child status. Image properties of prenatal placenta and amniotic fluid are immediately examined with ultrasound in 267 cases of postterm pregnancy beyond prediction at Obstetric Department, Hue Central Hospital. Results: In postterm pregnancy, placenta thickness decreases gradually according to gestational age. Oligohydramnios is 30.3%. There is a correlation between amniotic fluid index and birth method with r = 0.41. Sensitivity is 89.15%. Specificity is 48.55%. There is also a correlation between amniotic fluid echogenicity and method of birth: r = 0.478. Sensitivity is 97.67%. Specificity is 42.75%. Amniotic fluid index and baby Clifford's syndrome are also relevant, with r=0.466. Sensitivity is 83.78%. Specificity is 78.26%. Conclusions: Ultrasound scanning of amniotic fluid properties should be noted in the case of postterm pregnancy.

Abstract The improvement of carcass traits is an important breeding objective in beef cattle breeding programs. The most common way of selecting for improvement in carcass traits is via indirect selection using ultrasound scanning of selection candidates which are submitted to genetic evaluation programs. Two systems used to analyse ultrasound images to predict carcass traits are the Pie Medical Esaote Aquila (PIE) and Central Ultrasound Processing (CUP). This study compared the ability of the two systems to predict carcass traits for genetic evaluation in Australian Angus cattle. Genetic and phenotypic parameters were estimated using data from 1648 Angus steers which were ultrasound scanned twice with both systems, first at feedlot entry and then following 100 days in the feedlot. The traits interpreted from ultrasound scanning included eye muscle area (EMA), rib fat (RIB) rump fat (RUMP) and intramuscular fat (IMF). Abattoir carcass data were collected on all steers following the full feedlot feeding period of 285 days. For all ultrasound scan traits, CUP resulted in higher phenotypic and genetic variances compared to the PIE. For IMF, CUP had higher heritability at feedlot intake (0.51 for CUP compared to 0.37 for PIE) and after 100 days feeding (0.54 for CUP compared to 0.45 PIE). CUP predicted IMF also tended to have stronger correlations with the breeding objective traits of carcass IMF marbling traits, both genetically (ranging from 0.59 to 0.75 for CUP compared to 0.45 to 0.63 for PIE) and phenotypically (ranging from 0.27 to 0.43 for CUP compared to 0.19 to 0.28 for PIE). Ultrasound scan EMA were the only group of traits in which the heritabilities were higher for PIE (0.52 for PIE compared to 0.40 for CUP at feedlot intake and 0.46 for PIE compared to 0.43 for CUP at 100 days of feeding), however with similar relationships to the breeding objective carcass EMA observed. For subcutaneous fat traits of ultrasound RIB and RUMP, the heritabilites and genetic correlations to the related carcass traits were similar, with the exception being the higher heritability observed for CUP predicted RUMP at feedlot intake at 0.52 compared to 0.38 for PIE. The results from this study indicates that the CUP system, compared to PIE, provides an advantage for genetic evaluation of carcass traits in Angus cattle, particularly for the IMF and associated marbling traits.
