[Evaluation of the ability to regulate blood volume under standardized motoric stress].
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.
