Measurements of hematocrit, total plasma protein and red cell volume were made during sexual excitement and copulation in boars. Red cell volume (RCV) was determined by isotope dilution technique using endogenous 51Cr-tagged red cells. Basing on these data changes in the total blood volume (TBV) and plasma volume (PV) were calculated by 2 indirect methods. RCV increased by 12% to 16% in the intial phase of ejaculation and remained increased during ejaculation and 40 minutes after copulation. TBV and PV decreased during copulation, greatest drop being found in the final phase of ejaculation. After ejaculation the TBV was increasing, first to the resting value before copulation (about 20 minutes after copulation), thereafter it became markedly higher than during the resting period. Depending on the method used for calculation significant differences were found in the quantity of TBV and PV drop during ejaculation.
在公猪性兴奋和交配过程中，对血细胞比容、血浆总蛋白和红细胞体积进行了测量。红细胞体积（RCV）采用内源性51Cr标记红细胞的同位素稀释技术测定。基于这些数据，通过两种间接方法计算了总血容量（TBV）和血浆容量（PV）的变化。在射精初始阶段，RCV增加了12%至16%，在射精过程中和交配后40分钟内一直保持增加。交配期间TBV和PV下降，在射精最后阶段下降幅度最大。射精后TBV开始增加，首先升至交配前的静息值（交配后约20分钟），此后明显高于静息期。根据计算方法的不同，射精期间TBV和PV下降的量存在显著差异。
