“…The stage of pregnancy was assessed by measuring the crown-rump length of the foetuses [15]. As in previous works, the placentae were collected after day 100 [9,10]; in this study the period was focused on days 60 to 100.…”

-Pregnancy-associated glycoproteins (PAG), structurally related to aspartic proteinases, are expressed in the outer epithelial cell layer (chorion/trophectoderm) of the ungulate placenta. The aim of the present study was to isolate as many PAG molecules as possible from placentae collected between day 60 and day 100 of gestation and to characterize their amino-terminal amino-acid sequences. Three heterologous radioimmunoassays were used to monitor PAG immunoreactivity throughout the isolation procedures. Sequential use of DEAE-cellulose, gel filtration, and CM ceramic chromatographies led to the isolation of several fractions rich in PAG immunoreactivity. The fractions with a large amount of proteins were also purified by chromatofocusing. The analysis of immunoreactive fractions by SDS-PAGE, Western blotting and two-dimensional electrophoresis followed by amino-terminal microsequencing on PVDF membranes allowed to identify eight different ovPAG with apparent molecular masses ranging from 55 to 66 kDa and isoelectric points from 4.0 to 6.8. The N-terminal sequences were determined and their comparison to those previously identified revealed that four of them are identical to those encoded by previously known cDNA, while the additional four sequences appear to be novel since they have not yet been described. ovine / pregnancy-associated glycoprotein / placenta / multiple forms / N-terminal microsequencing

“…The head was flexed at right angle to this line. The body measurement in respect to Crown-rump length (CR length), Curved Crownrump length (CVR length), height at withers and height at pin of fetuses were taken and recorded in centimetres (cm) using non-stretchable thread and scale as per the method adopted by Joubert, (1956) (Table 1). The approximate age of goat fetuses was estimated on the basis of CR length as per the normograph of Lyngset (1971).…”

The present study was carried out on tongue measurements in Surti goat fetus to establish the relationship among various biometric measurements of the tongue and body in relation to prediction of fetal age. Total 39 apparently normal Surti goat fetuses were procured and categorized into three groups based on Crown-rump length. The body measurements like Crownrump length, Curved Crown-rump length, height at withers and height at pin of fetuses were taken. The biometrical measurements of the tongue were recorded identically weight, length, width, thickness and circumference. Tongue biometry and body measurement's association determined by simple linear correlation. Attempts were made for development of prediction equation for prediction of fetal age with tongue and body measurements. All the biometric measurements of tongue increase significantly (p0.05) with advancement of age. Association among biometric measurements of the tongue and body expressed high degree of positive correlation. Predictability of regression equations is very high for prediction of fetal age. All biometric and body measurement's correlations are highly significant (p0.01).
