Abstract
This study was carried out the determine the progesterone concentration for serum by enzyme-linked immunosorbent assay(ELISA) in bovine adult at estrous, pregnant, after patuation and male, female calves of 1 month old, respectively. The results obtained were summarized as follows ; 1. The assay has a sesitivity of $0.1ng/m{ell}$. 2. Intra and inter-assay coefficient of variation were 4.5%, 6.1~9.4% when used for the determination of progesterone in samples of bovine serum. 3. The percentages of recovery for progesterone added were between 88.0 to 88.9%. 4. Progesterone concentration of adult bovine serum at estrus, pregnant and after 1 day of parturition were $0.37{pm}0.16$, $7.1{pm}1.0$, $0.13{pm}0.02ng/m{ell}$, respectively. 5. There was no differences in serum progesterone concentration of calves both male($0.16{pm}0.03ng/m{ell}$) and female($0.15{pm}0.04ng/m{ell}$) on 1 month old. From these results, progesterone determination by ELISA is very applicable to detect of early pregnancy diagnosis, factorial analysis of reproductive disorder, and also reproductive physiological functions such as veterinary therapeutic measures and monitoring of cyclicity.
Key Words: enzyme-linked immunosorbent assay(ELISA), progesterone, coefficient of variation, serum, bovine
