Semen was collected from six stud dogs to compare five extenders in the semen freezing process. Each ejaculate was divided in five parts and added to tris-fructose-citric acid, glicine, lactose, skim milk and tris-fructose-citrate extenders. The semen was diluted at 37°C in extenders without glycerol, in the ratio 1:1 and cooled for 60 minutes to reach a 5°C temperature. Then, extenders with glycerol in the ratio of 2:1 were added to give the final prefreezing concentration of 4% of glycerol. The diluted semen with the cryoprotectant was maintained for a further 60 minutes in refrigeration to equilibrate the spermatozoa in the glycerol and packaged in 0.5 ml plastic straws. The straws were maintained for 30 minutes in vapor, plunged and sto...
