The packed cell volume(PCV) of Korean native goat, volume percentage of red blood cell in whole blood, was reshuffled of 20%, 40% and 60% using autoplasma, and erythrocyte sedimentation rate was measured in Westergren tubes at room temperature () and low temperature (). The sedimentation rates of red blood cell obtained are summarized as follows. The erythrocyte sedimentation rates of Korean native goat are accelerated more at high temperature than low temperature. The erythrocyte sedimentation rates of reshuffled Korean native goat upon time are almost linear for several hours. The erythrocyte sedimentation rates of Korean native goat are settled faster at low PCV than higher PCV, i. e., there is a reverse relationshif between the erythrocyte sedimentation rate and packed cell volume.

Orchardgrass(Dactylis glomerata L.) hays, which had been harvested in different seasons and grown with different levels of potassium (K)fertilizer, were fed to foats in metabolic cages in order to know the effect forage mineral content on mineral balance
