[Effect of a urea diet on glutamate dehydrogenase and glutamine synthetase activity in various organs of chickens]. / Vplyv mocovinovej diety na aktivitu glutamátdehydrogenázy a glutaminsyntetazy v niektorých orgánoch brojlerov

The total values were determined for the activity of glutamate dehydrogenase, glutamine synthetase, and dehydrogenase with pyruvate in broilers fed a diet with a 0, 2 and 4% content of urea for three weeks. A statistically significant increase of glutamate dehydrogenase activity was ascertained in the liver and kidney of broilers. The increase of the activity of glutamine synthetase in liver was close to the threshold of statistical significance. Dehydrogenase activity with pyruvate increased in liver.
