[Enzyme constellation of the blood plasma in the prognosis of decreased adaptability in newborn calves].

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.
