[Effect of physical stress on the indices of acid-base homeostasis in pigs].
Investigated was the effect of physical stress--fixation with a cord at the collection of blood--on the values of the indexes of the acid-base homeostasis of the blood of pigs. It was found out that there existed two types of pigs reacting differently to physical stress. One is a labile type in which, after the stress, there occurs a rapid decrease of the pH of the blood, and the second is a stable type, in which the pH of the blood does not change. The decreasing of the pH in blood is more frequent in younger age categories of fattening pigs and gilts. Application of tranquillizers decreased, to a considerable extent, the occurrence of changes of the acid-base homeostasis of blood.
