The effect of the system of mating and the way of killing on the aldolase activity in the tissue of rabbits was the task of this research work. The research work was realized in 201 New Zealand white rabbits aged 140 days, mated outbred and inbred. Two methods of killing were used: classical method, which was based on the stroke and break the spinal cord; and killing with the help of treating with an i/m infection of 10 per cent of magnesium sulphate (2 ml per 1 kg of weight). In blood serum and in liver homogenates, kidneys and dorsal muscle the aldolase activity was determined by the method of Bruns. No significant differences in the aldolase activity between outbred and inbred rabbits were found. Statistically high significant differences, conditioned by killing method, were stated in activity of enzyme.
