Radioimmunoassay of FSH in the plasma of post-partum dairy cows.
A method for measurement of bovine plasma FSH has been established with an interassay coefficient of variation of 15.5% over the workable range of the assay. Compared to values at the end of pregnancy (42-122 ng/ml), FSH concentrations were greater (P less than 0.01) between 0 and 20 days post partum in 3 cows.
