HISTOMORPHOLOGIC AND HISTOCHEMICAL-CHARACTERISTICS OF CARPAL GLANDS (GLANDULAE-CARPEAE) IN DOMESTIC SWINE (SUS-SCROFA-DOMESTICUS) AND WILD SWINE (SUS-SCROFA-FERUS)

Investigations were carried out on samples from carpal glands of domes tic and wild swine of different ages. The anatomic position of carpal glands is identical in domestic and wild swine. Glandular acini in dom estic swine are bigger and more scarce than in wild swine. LDH activit y is more intense in wild swine, while the activity of the investigate d diaphorases is almost even. The activity alkaline and acid phosphata se is stronger in domestic swine, while the activity of non-specific e sterases is present only in wild animals. The more or less manifest pr esence of all investigated enzymes indicates that carpal glands in dom estic and wild porcine specimens are very active metabolically. Regard ing the intensity of enzymatic reactions, some differences are probabl y due to different sexual maturity, as well as to the method of feedin g and housing in these groups of animals.
