FEDETS, O., 2015. Comparison of activities of glutathione enzymes in ceacum and liver of cattle, horse, pig, rabbit and sheep. Bulg. J. Agric. Sci., 21: 698–702

The level of glutathione and activities of glutathione S-transferase, glutathione peroxidase and glutathione reductase in caecum and liver of food-producing animals have been investigated and compared. The activity of glutathione S-transferase is the highest in the liver, but that of glutathione reductase is the highest in mucosa of caecum. Pig and rabbit have significant differences of glutathione peroxidase activity in caecum and liver. The highest content of glutathione and activity of glutathione S-transferase were in sheep liver and rabbit caecum, the lowest were in cattle. The highest glutathione peroxidase activity was in pig liver and cattle caecum. In horse the activities of glutathione peroxidase and glutathione reductase were the lowest. The highest glutathione reductase activity was in liver of cattle and caecum of cattle and pig.

Key words: glutathione enzymes, caecum, liver, farm animals
Abbreviations: GST – glutathione S-transferase; GPx – glutathione peroxidase; GR – glutathione reductase; GSH – glutathione; GSSG – oxidized glutathione
