Sire contribution to pregnancy loss and pregnancy-associated glycoprotein production in nelore cows
(2018-02-01)
Pregnancy loss is a major contributing factor to reproductive inefficiency in both the beef and dairy industries. Sires can have a significant influence on the amount of pregnancy loss; however, this relationship is still ...
Sire Effect on Pregnancy Associated Glycoprotein (PAG) Concentrations in Nelore Beef Cows.
(Amer Soc Animal Science, 2017-01-01)
Pregnancy diagnosis in cattle using pregnancy associated glycoprotein concentration in circulation at day 24 of gestation
(Elsevier B.V., 2018-01-15)
Cattle producers are limited to day 28-30 of gestation as the earliest time point for accurate pregnancy diagnosis due to the effectiveness of ultrasound and chemical based methods, including commercially available pregnancy ...
The ability to predict pregnancy loss in cattle with ELISAs that detect pregnancy associated glycoproteins is antibody dependent
(2018-03-01)
The concentration of circulating pregnancy associated glycoproteins (PAGs) early in pregnancy may serve as markers to predict late embryonic mortality or fetal mortality in cattle. In this study, pregnancies were established ...
Using pregnancy-associated glycoproteins to provide early pregnancy diagnosis in Nelore cows
(Elsevier B.V., 2018-08-01)
Pregnancy-associated glycoproteins (PAG) are expressed in the placenta of ungulate mammals. Ruminants secrete PAGs continuously from embryonic implantation until delivery. In this study, we evaluated the feasibility of ...
Use of bovine pregnancy-associated glycoproteins to predict late embryonic mortality in postpartum Nelore beef cows
(2016-06-01)
The primary objective was to determine if circulating concentration of bovine pregnancy-associated glycoproteins (bPAGs) on Day 30 after artificial insemination (AI) may serve as a marker of late embryonic mortality in Bos ...
Association of concentrations of beta-carotene in plasma on pregnancy per artificial insemination and pregnancy loss in lactating Holstein cows
(Elsevier B.V., 2020-01-15)
The objective of this study was to determine the association of beta-carotene concentration in plasma at the moment of artificial insemination (AI) on pregnancy/AI in lactating Holstein cows. A total of 399 events from 364 ...
Circulating concentrations of bovine pregnancy-associated glycoproteins and late embryonic mortality in lactating dairy herds
(Elsevier B.V., 2016-02-01)
The objectives of these experiments were as follows: (1) to determine the association between circulating concentrations of pregnancy-associated glycoproteins (PAG) and late embryonic mortality (EM) in lactating dairy ...
Markers of pregnancy: How early can we detect pregnancies in cattle using pregnancy-associated glycoproteins (PAGs) and microRNAs?
(2016-01-01)
Pregnancy detection has evolved over the last few decades and the importance of early pregnancy detection is critical to minimize the amount of time a cow spends not pregnant. Embryonic mortality (EM) is generally considered ...
Genetic and nongenetic profiling of milk pregnancy-associated glycoproteins in Holstein cattle
(Elsevier B.V., 2018-11-01)
Pregnancy-associated glycoproteins (PAG) are secreted by the trophoblast and are detectable in maternal circulation around the time of attachment of the fetal placenta, as well as in blood and milk throughout gestation. ...
