The nitrogen assimilation of the lizard, Takydromus tachydromoides, was estimated by means of micro-Kjeldhl method, feed on the larvae of the fly, Lucilia illustris.
The yearly amount of nitrogen consumption, in the case of an adult lizard, is 177.9mg, and the amount of nitrogen assimilation is 102.72mg, thus the efficiency of assimilation is 57.7%. The efficiency of assimilation in November indicates extremely small. This may be cased by that they are ready to the hiberation.
