title: [Concentrations of prolactin, LH, estradiol-17 beta and progesterone in swine after biotechnical stimulation with PMSG, HCG and suidor].
abstract: Concentrations of estradiol-17 beta, progesterone, luteinising hormone (LH), and prolactin were recorded from 9 gilts, following cycle blocking by means of Suisynchron(R)-Prämix and application of PMSG, HCG, and Suidor(R). A radio-immuno-assay which for its quality criteria enabled safe determination of the hormone in peripheral blood had been worked out specifically for prolactin appraisal. HCG application led to blockage of pre-ovulatory LH release in 7 of 9 animals. Possible causes are discussed. Prolactin concentrations during oestrus were differentiated and, for example, were characterised by strong oscillatory variations. With the experimental arrangement used, the boar pheromone Suidor(R) was not found to have any impact upon hormone profiles.
