Summary
The aim of the study was to test the applicability of commercial progesterone enzyme immunoassay (EIA) kit for faecal gestagen determination in sows. Faecal gestagen and plasma progesterone concentrations were measured by Ovucheck 96 Well. Changes in faecal gestagen (progesterone and its metabolites) concentration during the oestrous cycle or pregnancy significantly correlated with plasma progesterone levels. The results indicate that measurement of faecal gestagens in sows by using commercial EIA kit is suitable for progesterone status detection in healthy animals, but is not appropriate in animals suffering from diarrhoea. After completing their function in the organism steroids are deactivated by glucuronate and sulphate conjugation in the liver and excreted in urine by the kidneys or via bile released into the gut (Tay lor 1971).
