Plasma thyroxine and triiodothyronine levels after induction and synchronization of estrus in the anoestrous season in ewes
Abstract
The thyroid hormonal status of ewes after induction and synchronization of estrus in the anoestrous season was investigated by determination of plasma triiodorthyronine (T 3 ) and thyroxine (T 4 ) concentrations using radioimmunoassay (RIA). Samples of jugular venous plasma were collected on the day of sponge insertion (P), at estrus (day 0.) as well as 7, 14 and 18 days after estrus. Plasma T 3 and T 4 levels in the control group of anoestrous ewes were significantly higher than those in the ewes after synchronization of estrus, except, for the level of T 3 on days 14. and 18. after estrus, and T 4 on the day of sponge insertion.
