Sixteen German Landrace pigs of the meat type were kept in individual cages (0.47 m2 floor area each) or in two pens of four pigs providing 1.05 m2 per animal, under otherwise identical conditions for 45 days, commending at a body weight of 45 kg. Plasma volume and plasma glucose were determined before, during and after the pigs made to run on a band moving at 1 m/s for 20 minutes at 24 degrees C. Changes in plasma volume were studied from the total scatter of values (total area covered by the curve of values). This made it possible to quantify individual regulatory capacity and the influence of management. Close confinement in an individual cage reduced the regulatory capacity of the plasma volume by 3.5 to 4 times. There were significant qualitative and quantitative relationships between intravascular fluid volume and intravascular glucose or glucose concentration.
16头肉用型德国长白猪被分别饲养在个体笼中（每个笼的占地面积为0.47平方米），或者饲养在两个围栏中，每个围栏饲养4头猪，每头猪的占地面积为1.05平方米，在其他条件相同的情况下饲养45天，初始体重为45千克。在24摄氏度的环境下，让猪在以1米/秒速度移动的传送带上奔跑20分钟，在奔跑前、奔跑期间和奔跑后测定血浆容量和血浆葡萄糖。根据数值的总离散度（数值曲线覆盖的总面积）研究血浆容量的变化。这使得量化个体调节能力和管理的影响成为可能。单独关在个体笼中会使血浆容量的调节能力降低3.5至4倍。血管内液体容量与血管内葡萄糖或葡萄糖浓度之间存在显著的定性和定量关系。
