EG is good but you need to use only 1.5 Molar, you can freeze them only if you flush the mare 6 days after ovulation, only morulae or very ealy blastocysts and you need only cristal 0.25 ml straws (IMV ZA 133. They can't be absolutely frozen on a floating rack but you need an embryo freezer (Bio cool IV, or a Cryologic or a RPE freezer etc.) because you must do a seeding on your straws etc. The e.t. supplies are sold by many Company like AB Technology (Pullman WA) or PETS Inc. or AG Tech etc. I hope to have answered enough for your needs....but if you want ask me what you desire!
