title: [The content of pepsinogen in the blood plasma of growing fallow deer (Dama dama L.) raised helminth free and under natural conditions in captivity].
abstract: Pepsinogen values were determined in helminth free (n = 12) and naturally raised farmed fallow deer (n = 10-12) from birth (June 1992) to 11 (May 1993) and 15 months (September 1993) of age respectively in 4 weekly intervals. At birth the plasma pepsinogen value was 0.708 +/- 0.197 U Tyrosin/l and decreased thereafter until 14 weeks of age to 0.139 +/- 0.061 U Tyrosin/l in both groups. From the 18th week of age the naturally raised fallow deer, infected with gastrointestinal nematodes, had significantly higher pepsinogen values than the helminth free kept animals. Maximum pepsinogen levels in the naturally raised fallow deer were determined in November 1992 (0.813 +/- 0.336 U Tyrosin/l) and in June 1993 (1.050 +/- 0.163 U Tyrosin/l). In helminth free animals no further decrease of plasma pepsinogen values was seen from 14th week of age onwards: it was 0.202 +/- 0.110 U Tyrosin/l. There was no influence of sex on the plasma pepsinogen values in both groups.
