Abstract

The purpose of this study is to characterise progesterone concentration in Bali cows before, during and after pregnancy. This study enables pregnant status to be detected shortly following conception in Bali cow. Five Bali cows and one Bali bull were used in this study, between July 2010 and September 2011. The concentration of progesterone in the blood serum was analysed using Enzyme-Linked Fluorescent Immunoassay principle in Enzyme Linked Immunosorbent Assay method. Cow bodyweight increased during pregnancy aligned with foetus development in uterus. The progesterone concentration in non-pregnant cow was 1.32 ± 0.93 ng/ml over 11 months of observation. For the pregnant cows the progesterone concentration was 0.76 ± 0.64 ng/ml before pregnant and increased pronouncedly ranging between 7.43 ± 5.27 and 16.7 ± 2.29 ng/ml from the first up to the 7th month of pregnancy, then slightly declined toward parturition, between 11.55 ± 0.71 and 8.46 ± 5.33 ng/ml, and plunged down markedly to level of 0.89 ± 0.24 ng/ml following parturition. Progesterone concentration were markedly different in pregnant versus non-pregnant Bali cows. This allows pregnant status of Bali cow to be detected shortly following conception.
