[more ▼] Pregnancy-associated glycoproteins are powerful pregnancy markers in domestic cattle. These proteins are expressed in mono- and binucleate trophoblast cells from the first days of gestation until calving. Different molecules were identified as being expressed at various stages of pregnancy. However, up to date, their functions and activities during pregnancy were not yet established. Specific RIA tests were developed (classic and alternative RIA) and used to measure the concentration of these glycoproteins in blood during gestation and the postpartum period in cattle. In maternal blood, PAGs rise to detectable levels from the 24th-28th days after fertilization. A recent study indicated that PAGs can also be detected in milk samples. However, concentrations in milk are much lower when compared to those of plasma.

[more ▼] This study is carried out to determine ovine pregnancy associated glycoprotein (oPAG) levels in the serum of Berrichone ewes throughout gestation and the first month post partum. The levels were determinated with heterologous RIA using bovine PAG as standard and tracer and rabbit antiserum against oPAG. The level of oPAG increased from the 4th week of pregnancy till 12-13th week and decreased slowly till 17th week, when increased rapidly and reached the highest level (around 600-700 ng/ml). In the sheep carrying twins, we observed higher levels of oPAG than in the uniparous sheep. After lambing, oPAG decreased rapidly in 4 week to basal values. The oPAG concentrations in the animals carrying twins was higher when comparised to single lamb. We concluded that the oPAG level depends on the number of lambs and term of pregnancy. The estimation of oPAG concentrations in the blood can be used as a indicator for pregnancy diagnosis. [less ▲] Detailed reference viewed: 98 (3 ULg) |
