It really depends on your goal. We put embryos in about half of our females, and the best ones get AI'd. Our embryologist puts one in for $85, and he comes to our place. He will do one or several, what ever you have. I have bought embryos as cheap as $100 each, and they can go pretty high! The key is to know what genetics you want, and use them that way. We buy embryos sired by bulls that are really expensive and exclusive (not something you would use to just AI), and out of cows that have some top genetics. We use natural heats, so no expense in setting up a recip. Our best success story is a set of 5 eggs we bought for $100 each, we have put in three so far, one heifer on the ground (outstanding!), one heifer due in October, and another pregnancy due in March. We still have two eggs in the tank. It does not always work out that great though; it seems we get more bulls with the embryos than heifers! But definitely worth the try if you want to get some better or top genetics, and CHEAPER than trying to go buy them!
