Abstract
OBJECTIVE
The main aim of the present study was to detect bovine fetal DNA in the maternal circulation, a relatively unexplored subject in the literature.
STUDY DESIGN
DNA was extracted from blood of 84 primipara cows (Bos indicus) at different gestational ages (30-270 days) and from 100 adult animals (50 males and 50 non-pregnant cows). The samples were analyzed using PCR with primers for TSPY gene.
RESULTS
Molecular results matched the fetal phenotypic gender in all 47 male and 37 female fetuses, including early pregnancy, and in control animals.
CONCLUSIONS
These results evidence a bovine transplacental fetal DNA passage.
