The use of a pregnancy-specific antigen, chorionic somatomammotrophin, as an indicator of pregnancy in sheep

H A Robertson et al. J Reprod Fertil. 1980 Jan.

Abstract

Measurement of the serum concentrations of ovine chorionic sommatomammotrophin (oCS) showed that the values could be used to distinguish non-pregnant (100%) and pregnant (97%) ewes from Day 64 after mating. Values of oCS in non-pregnant ewes were less than 5 ng/ml.
