ABSTRACT

Despite proven ability of pregnancy-associated glycoproteins (PAGs) for early detection of pregnancy in several livestock, studies on its diagnostic reliability in Aardi goats are lacking. Thirty-two healthy mature Aardi does, managed under an intensive condition, were screened for pregnancy at 1, 7, 15, 23, 35 and 60 days post natural mating (NM) to evaluate the ability of utilizing caprine pregnancy-associated glycoproteins (caPAGs) compared to other methods frequently applied -but have several setbacks- in screening goats for early pregnancy diagnosis. According to the enzymatic-immunoassay data, our results indicated that pregnant Aardi does had higher (P 0.05) between the sensitivity, specificity, predictive values, and accuracy of serum caPAGs and other methods as early as day 23 post NM. Moreover, both serum caPAGs and US technique were proven to give higher (P y diagnosis in Aardi goats. In conclusion, the obtained results herein clearly demonstrated that enzymatic-immunoassayed serum caPAGs, as a direct, simple, accurate, inexpensive, practical and fast screening measure, was greatly feasible for distinguishing pregnant from non-pregnant as early as day 23 post NM, which is crucial to treat fertility problems early and efficiently.
