- This is an area that seems to have a lot of opinions. I’ll start by describing the different containers.

The one most people are familiar with is a large blue one that looks like a cylindrical ice chest. It is called an Equitainer. It is reusable and the semen is cooled by one or two coolant cans depending on which Equitainer you purchase. The coolant cans have been designed to cool the semen at a specific rate. The heavy duty construction of the Equitainer helps maintain the correct temperature regardless of the outside temperatures.

Another one that is similar in design to the Equitainer is the Expecta Foal Disposable Container. It is basically a Styrofoam insulated cardboard box with a mini thermos in the middle and ice packs to cool the semen. It will withstand a few shippings but is sold as "disposable". It is approximately the same size as the Equitainer.

The last one is Bio-Flite "Disposable" Cooled Semen Container. It is similar to Expecta Foal but smaller. I worry its temperature would fluctuate too much with the outside temperature as there is not a lot of insulation. However, I know of people who are quite happy with its results. I would recommend having one for short distances at moderate temperatures.

If you do decide to invest in a container the Equitainer is usually considered the industry standard. It is sold by Hamiton-Thorn Research. You can reach them at 1-800-367-0266. Be sure to buy two sets of coolant cans. If one set went out with a shipment, you will already have another set ready to go out as soon as your container is returned. Otherwise you’ll be left waiting for the coolant cans to freeze before you can use your container again.  In 1998 I found 1 Equitainer per every 4 or 5 mares you have booked works well.  The first year this may seem like quite an expense, but remember they are very durable and should last you many breeding seasons.  The last thing you want to do is have mares booked and ready for shipments, but have nothing to ship the semen in because they are all out.   That it is also why it is extremely important to have your mare owners give deposit on your equitainers and have a daily late fee of at least $25.  This is the only way to insure the prompt return of your containers.
