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