Sažetak
The objective of the present study was to compare transrectal ultrasonography and pregnancy associated glycoprotein (PAG) tests for determination of pregnancy in Holstein-friesian heifers imported in Croatia. 72 heifers imported from Holland were used in present study. All came to Croatia with written confirmation of pregnancy. During caranteen we preformed rectal and ultrasound exploration of heifers and simultaneusly collected blood samples from each heifer. PAG concentrations were determined by a RIA imunoassay using bovine PAG 67 KDa as a tracer and standard. In our study 68 hefers confirmed to be pregnant by both methods and 4 cows were confirmed for abortion by PAG test and nonpregnant for ultrasound checking. Transrectal ultrasonography is accurate test for pregnancy diagnosis in pregnant heifers but it is impossible to say only on basis of ultrasound examination if heifers conceived and aborted or they failed to conceive in the first place. PAG RIA test is not only highly accurate and reliable method to distinguish between pregnant and nonpregnant heifers on the market. It is also usefull to determine whether heifers were pregnant and embryo died and was absorbed during the trasfer or heifers failed to conceive. It is possible because level of PAG persists in circulation after abortion or embrional death. In doubtfull cases it can be used as a proof of pregnancy existence in heifers later confirmed to be nonpregnant
