Developmental changes of carbonic anhydrase activity of parotid gland and stomach of goat

1. Carbonic anhydrase activities in the various tissues of ruminants and non-ruminants were compared. 2. The highest activity was found in the parotid gland of ruminants such as bovine and goat. However the activity in the kidney was not significantly different between the ruminants and non-ruminants. #. The effect of development on the carbonic anhydrase activity was studied. The activities in both the parotid gland and kidney of the goat were found to increase with age whereas the activities of the pancreas, liver and submaxillary gland did not change significantly. 4. The activities in the abomasum of the goat also increased with age however the other stomachs did not vary prominently.
