[Results of continuous gas measurements rabbit housing by using multi-gas monitoring].

Investigations of slatted floor keeping of rabbits in an air conditioned chamber with multigas monitoring over a period of more than two month have shown that the average values per week were on a low level between 575 and 685 ppm (carbon dioxide), 3.4 and 5.6 ppm (ammonia) resp. Concentration of ammonia reached in maximum 12.3 ppm for a short time. Nitrous oxide concentration was measured on a global value (253 up to 317 ppb). A slight tendency of increasing CO2 and NH3 values with the begin of light period--obviously related to increased locomotoric activity--approximately was observed. In slatted floor keeping calculated emission of ammonia was very low (0.23 gram per 500 kg an hour).
