[Usefulness of selected enzymatic methods for coprological examination of calves]

Methodical analysis of glutamic oxalacetic transaminase, glutamic pyruvic transaminase, alkaline phosphatase and gamma-glutamyltransferase activity in calves faeces was performed. The faeces from both healthy and diarrheic Holstein-Friesian calves, aged from 1 to 10 days, were used. For each enzyme the repetition and representativity of single determination was examined respectively in soft and dry matter. The results of our analysis show that normal enzymatic methods may be used for the determination of glutamic oxalacetic and glutamic pyruvic transaminases as well as gamma-glutamyltransferase. Further investigation methods are needed for determination of alkaline phosphatase activity in faeces.
