1.1.1.103 additional information
-
 specific activity in animals fed a standard diet is 11times higher than in the liver of rats fed a standard diet. Enzyme activities in the livers of fasting and threonine-rich diet groups are three and two times higher than in the group fed with standard diet Coturnix japonica
1.1.1.103 additional information
-
 specific activity in Japanese quail fed a standard diet is 11times higher than in the liver of rats fed a standard diet. Enzyme activities in the livers of fasting groups are the same level as in the group fed with standard diet Rattus norvegicus
4.3.1.19 additional information
-
 activity is much higher in rat liver than in quail liver, regardless of the nutritional state. The specific activity in the normal rat liver is 15times higher than that of the control quail group. The specific activity in rat liver after fasting increases by a factor of 2.3 over that of normal fed state Rattus norvegicus
4.3.1.19 additional information
-
 activity is much lower in quail liver than in rat liver, regardless of the nutritional state. The specific activity in the normal rat liver is 15times higher than that of the control quail group. Activities in liver of the fastened, the 1% threonine-enriched and the 5% threonine-enriched group are about 2, 1.3 and 1.5times higher, respectively, than that of the control group of quails Coturnix japonica
