摘要

通过Suisynchron(R)-Prämix和PMSG、HCG和Suidor(R)阻断周期,记录9头母猪的雌二醇-17 β、孕酮、黄体生成素(LH)和催乳素的浓度。我们专门为催乳素的鉴定制定了一种放射免疫测定法,其质量标准能够安全测定外周血中的催乳素。应用HCG导致9只动物中7只的排卵前LH释放受阻。讨论了可能的原因。催乳素浓度在发情期间是有差异的,例如,具有强烈的振荡变化的特征。在实验安排下,未发现猪信息素Suidor(R)对激素谱有任何影响。

[Concentrations of prolactin, LH, estradiol-17 beta and progesterone in swine after biotechnical stimulation with PMSG, HCG and suidor].

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.
