Abstract
Early pregnancy detection in dairy cows {Bos taiinis) is an integral part of a rational and successful animal husbandry practice. In this respect a plethora of pregnancy detection techniques have been tried in cows with variable degrees of reliability. These techniques broadly comprise physical (rectal palpation, radiography, laparoscopy and ultrasonography), chemical (cuboniĆ¢ s test,), biochemical (assay of hormones and pregnancy specific proteins by radioimmunoassay), immunological (rosette inhibition test for early pregnancy factor) (Wani et al., 2003) and biological methods (Ascheim-Zondek test).
