Sažetak
The aim of this study was to investigate the role of pregnancy associated glycoproteins (PAG) in early pregnancy physiology in cows as well as possibility of using PAG as diagnostic tool in diagnosis of embrionic mortality. In our research we used 74 cows of simmental breed aged 3-7 years, already used in reproduction and calved every year.. We divided cows in 3 groups: pregnant cows (n=34), nonpregnant cows (n=18) and cows experienced embrionic mortality (n=21). According to ultrasound and laboratory findings for progesteron and PAG in sera samples collected between 12. and 45. days after AI every 72 h, we concluded few things. First of all, it is impossible to determine embrionic mortality on basis of progesterone profil, but it is easy to distinguish pregnant from nonpregnant cows, if cows are supposed to be pregnant more than 21 day. In group of cows with embryonic mortality, it occured 17-24 days after conception in 98% cows. It was visible in drastic decrease of PAG 7, 5-9 days later (7, 5-9 days consists T2 for PAG in first month of pregnancy). Using PAG for pregnancy diagnosis enables us to prove existence of alive vital embryo in uterus 24 days after conception.
