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