In experiments on 6 sheep the authors found the following enzyme activities in bacteria in the rumen fluid, bacteria adhering to the epithelium of the rumen wall and bacteria adhering to food particles in the rumen (given in nkat X g-1 bacterial dry weight): GDH (NADH): 725 +/- 165, 558 +/- 127, 661 +/- 153; GDH (NADPH): 558 +/- 338, 255 +/- 88, 565 +/- 139; GOAT (NADH): 46 +/- 23, 67 +/- 31, 66 +/- 14; GOGAT/NADPH: 58 +/- 27, 56 +/- 15, 65 +/- 29; GS: 153 +/- 65, 69 +/- 35, 71 +/- 32; ALT: 71 +/- 25, 43 +/- 20, 52 +/- 11; AST: 52 +/- 12, 33 +/- 16, 28 +/- 15. The results show that, except for GDH (NADPH), there were no significant differences between the given enzyme activities in the rumen fluid and in bacteria adhering to the rumen wall and to food. Adherent rumen bacteria have the same potential possibilities as the rumen fluid bacteria for the utilization of ammonia, particularly for the synthesis of glutamic acid, glutamine, alanine and aspartic acid, with the above enzymes as catalysts. By means of the GS/GOGAT system, adherent rumen bacteria can probably synthesize glutamic acid in the presence of a limited NH3 concentration in the rumen.

The dynamic was studied of the enzyme activity of ChE, APh, Ald, GOAT, GPT, LDG, and CPh in 30 newborn calves. Fifteen of the animals developed coli bacteriosis later on. Blood was sampled at the 6th to 24th hour as well as on the 5th day following birth. At the 6th hour ChE, APh, Ald, and CPh of the diseased calves showed lower activity as against the enzyme activity of the unaffected animals. Similar trend was noticed also at the 24th hour. Contrary to the other enzymes of the constellation the changes observed in the activity of GPT were invariably connected with a considerable rise in diseased animals. The changes in the activity and dynamic of the investigated enzyme constellation can be used to forecast the incidence of coli bacteriosis.
