Abstract: This article reviewed the clinical diagnostics, laboratory diagnostics and circulating cell-free fetal DNA(ccffDNA) detection of pregnancy from the following four aspects:principle, method, diagnostic time and accuracy. Through the comparison and comprehensive analysis of the above methods, The advantages, limitations, research trends and the actual application effects of the above diagnostic methods were summarized, in order to provide suitable methods of livestock pregnancy diagnosis applied in different situations. The traditional clinical diagnostics have the double advantages of fast and cheap, but the accuracy is susceptible to the artificial operation. Laboratory diagnostics are earlier and more accurate, but they have disadvantages of lacking unified standard and costing more. The detection of ccffDNA can be used to identify fetal sex in domestic animals, whereas the specific markers of non-sex-dependent fetal DNA are still needed to be explored further.

Key words: radioimmunoassay, enzyme immunoassay, early pregnancy factor, pregnancy-associated glycoproteins, circulating cell-free fetal DNA
