Abstract (AI)
To develop a reliable approach to pregnancy diagnosis in sables based on noninvasive methods of hormonal status assessment, the concentrations of immunoreactive compounds (IRC) binding with antibodies to progesterone have been measured in the feces of females at different stages of the reproductive cycle. The results show that this concentration is higher in truly pregnant than in mated but nonreproducing females. An increase in the IRC concentration relative to its individual baseline level may be regarded as a reliable indication of true pregnancy.
Key Findings
1
An increase in fecal progesterone-immunoreactive compounds above an individual female’s baseline reliably indicates true pregnancy during the postimplantation period.
2
Fecal concentrations of progesterone-immunoreactive compounds were measured noninvasively across reproductive-cycle stages in female sables.
3
The findings support hormonal-status assessment in feces as a reliable noninvasive approach for diagnosing pregnancy in sables.
4
Truly pregnant females had higher fecal progesterone-immunoreactive compound concentrations than mated but nonreproducing females.
