“Chilled semen” is semen to which an extender has been added. This is done to help preserve the semen for transport to another country.
Once the semen of the dog has been collected it is examined with regards to its concentration and motility and the semen is then cooled to’5°C. The semen extenders allow the semen to be remained in a good health for 5-7 days Once the semen has reached its destination it is slowly brought back to its original temperature(37°C). Afterwards the semen is brought into the uterus of the bitch.
