The aim of the study was to establish normal ranges for chosen biochemical parameters of haemolymph of snails (Gasropoda: Mollusca), in the light of the use of these animals as experi- mental models in various types of studies. The study was conducted on 100 specimens of Cornu aspersum maxima (CAM) and 100 specimens of Cepaea nemoralis (CN). The haemolymph col- lected from the animals was analysed using colorimetry to assay aspartate transaminase (AST) activity, alanine transaminase (ALT) activity, amylase activity and the concentrations of urea and triglycerides. In the further part of the study, the influence of administering doxycycline with feed on the change of AST and ALT activity in snail haemolymph has been studied. The normal values established for CAM are as follow: AST activity: 26-38 u/l, ALT activity: 0-11 u/l, amylase activity 9-16 u/l, concentration of urea: 3-6 mg/dl, concentration of triglycerides: 16-20 mg/dl. For CN, the following data have been obtained: AST activity: 30-80 u/l, ALT activity: 0-15 u/l, amylase activity 12-15 u/l, concentration of urea: 5-8 mg/dl, concentration of triglycerides: 18-24 mg/dl. It has been shown that doxycycline presents a high workload on the hepatopancreas of snails, which is reflected by a statistically significant (p<0.05) increase of AST and ALT activity in the haemolymph of the specimens which obtained doxycycline in feed, as compared to the groups with antibiotic-free feed. The haemolymph activity of both studied parameters increased together with study time and tetracycline administration time.
