--- The objetive of this experiment was to evaluate the effect of the moment of addition of the glycerol during the curve of cooling on the spermatic quality of the canine semen. For this there were used 15 ejaculated of 4 adult dogs. There was evaluated the motility, volume, spermatic concentration and functional integrity of membrane of every ejaculated. Every sample of semen was submitted to 3 methods of addition of the glycerol (Treatment 1, Treatment 2 and Treatment 3) which differentiated for the concentration of glicerol present in the dilutor during the curve of cooling. In the Treatment 1 the whole of the glycerol was added to the beginning of the curve of cooling, in the Treatment 2 added to himself a fraction of the entire glycerol to the beginning of the curve of cooling and the remaining fraction at the end of the curve, finally in the Treatment 3 the glycerol was added at the end of the curve of cooling. Finished the curve of cooling the semen was packed in straw hats of 0.5 ml to proceed to the freezing in liquid nitrogen. The progressive motility and the functional integrity of membrane were the parameters used to evaluate the seminal quality to the post-thawing. There was not statistical difference between any of 3 methods of addition of the glicerol, in spite of this the Treatment 1 was keeping lightly better the motility and the functional integrity of membrane (44 % and 46 %) compared to the Treatment 2 (37 % and 36 %) and the Treatment 3 (38 % and 37 %). This demonstrates us that the moment of addition of the glycerol does not influence in a distinguishing way the progressive motility and the functional integrity of membrane being able thanks to this to simplify the process of criopreservación after the glycerol to add to the beginning of the curve of cooling since the semen would not be already manipulated up to the stiff one.
