CaniPlus Chilled Semen Extender LT
If you are shipping Chilled semen you need to add an extender. Without it the shipment will not survive. The extender provides the correct PH, nutirients, thermal stabalizers and antibiotics for the semen to survive up to 10 days.
I have used and tested many many extenders over the past decade. This is the best by a large margin. It has a two year shelf life. I can take a bottle from the fridge put in a cup of warm water, use just what I need and put the remainder back in the fridge for the next shipment.
I Collect just the sperm rich fraction 2-3mL for a Frenchie and add about 2x extender so the final volume i ship is around 6-8ml A bottle is good for about 4 shipments. Larger breeds will use more.
I have done side by side testing use our Shipate product on many extenders.
Yolk and milk based extenders are cheap but don't perform well (Kenney, Inra99, Exodus etc)
Two other extenders I have used sucessfully are from Camelot Farms and ICSB. Both are yolk based and do require freezing They have a shorter shelf life, and are more expensive becasue of shipping requirements. And they performed OK but not as wellas the Caniplus STDesigned to assure high conservation performance of canine semen The next generation of canine extenders from Minitube are 100% animal protein free. An additive prevents the need to add egg yolk and protects the sperm cells during chilled storage. It also protects the sperm cells from damage caused by temperature variations during shipping, prevents oxidative stress and neutralizes degrading metabolites negative effects. CaniPlus Chill ST has a shelf life of 24 months from date of production when stored at +4°C. Extenders maintain 70% of initial motility during the given period for storage / transport.
