In line with our continuing commitment to improve our service, we now have a fleet of temperature controlled delivery vehicles to ensure that all semen is delivered in the very best condition. The vehicles' customised shelving ensures an even airflow and a constant temperature of 17°C, which, tests show, is the optimum temperature to maintain maximum semen quality and fertility. Launched in 2002, the service boasts a 100% delivery record and the fleet of vans covers most areas of the country from the Scottish Highlands down to Devon.
