Background: The ejaculate of the dog has three fractions, the first and third containing prostatic fluid that is harmful to cryopreservation, and the second rich in sperm. Obtaining only the second fraction of the ejaculate is complicated; therefore, colloidal centrifugation was evaluated as a sperm selection method, plus the addition of glycerol in three concentrations 4, 6 and 8 % as cryoprotector. Methods: The study was conducted at the University of Cuenca-Ecuador, 72 seminal samples from 6 crossbreed dogs were evaluated. Each sample was divided into 2 aliquots, the first for Group 1 (conventional centrifugation) and the other Group 2 (colloidal centrifugation), once centrifuged each aliquot was sub-divided into thr...
