Peripheral plasma prolactin and progesterone levels in pseudopregnant goats during bromocryptine treatment.

Persistence of luteal function and accumulation of fluid within the uterus (hydrometra) are characteristics of pseudopregnancy in goats. To study the luteotrophic role of prolactin in this condition, seven seudopregnant goats were treated with bromocryptine (1 mg subcutaneously, twice daily) for 6 to 10 d. Plasma progesterone (P4) and prolactin (PRL) were measured by radioimmunoassay (RIA) in samples taken twice daily by venipuncture.
