I agree with Cowboy in that there are some really stupid rules when it comes to achieving export status on embryos, as well as most other forms of livestock genetics. We make sure all the embryos we collect are exportable, simply because our international markets are our best markets.Probably close to 90% of the embryos we sell, go to buyers outside of Canada, and by having embryos exportable, it literally has opened the world as a potential marketplace. Many of our donors have offspring in 6 countries, and there are several more countries that could open up to be potential markets very soon.
It is a little different, here in Canada, in that almost all the embryos collected are collected by veterinarians. This is probably because in the early years of ET, the vets made sure that they got rules in place that protected this as their own frontier. Somehow, they got most of the breed associations to agree to only register ET calves that had the embryo recovery documents signed by a licenced veterinarian. Since then, these rules have been relaxed somewhat, however I don't know of too many people pulling their own embryos. I think you do not have to be a veterinarian to collect and implant embryos for your own use, but I think you cannot do it for other people. I do know that in recent years, more and more producers are implanting more and more embryos for others.
There have been many studies done that have proven that trypsin washed embryos are 100% sterile, thus are 100% free of disease. International politics can oftentimes get involved, and sometimes countries put rules are put in place just to protect the breeders in that country. Three years ago, we thought we were going to lose one of our best embryo markets, Britain, as the British bureaucrats, decided that they would only accept embryos that were produced from sires that had been tested as IBR negative. There are not many bulls in Canada( or probably the US) that are IBR negative, as most breeders vaccinate their calves with IBR vaccines. Luckily for us, the British livestock breeders who wanted to have access to international genetics, lobbied hard against this ruling, and were successful to get it reversed.
The embryo washing itself, is a very simple process and it is also very low cost. Almost all our embryos are collected at one ET facility, and they wash the embryos are no cost to us. I have owned a few other donors in partnerships and we have used a couple other ET facilities, and one charged us $5 per embryo and the other charged $10 per embryo, to wash them.As far as testing the donors before they are flushed, we have never tested any of them prior to flushing. The only exception is for a while, we pulled a blood sample from the donors, when we flushed, if we thought the embryos were going to New Zealand. At the moment, the US, Britain, and Australia are fairly easy to move embryos too... but that could change in a moment's notice if some bureaucrat happens to get out of the wrong side of the bed in the morning! Earlier this spring, we had a group of embryos shipped with several other consignments of embryos, to Scotland. The tank was flown to London, cleared British customs and was then shipped by truck to Edinburgh. Some time between the time it cleared customs and before it got to Scotland, some British bureaucrat decided that the customs documents were not complete, so he declared that this tank of embryos was a potential hazard to British agriculture. The delivery driver was contacted by cell phone and was ordered to pull of the road and wait for the bureaucrats arrival. They seized the tank and immediately shipped it back to Calgary, Alberta. There was over $100,000 worth of embryos in this tank and it was sent back because someone had forgot to put an " x" in a box on one document. The papers were done again, and the tank was shipped back to Britain two days later... all for an additional cost of close to $3000 simply because an " X" was missed. Fortunately for us, the costs were picked up by the business who shipped them.
I have imported embryos from the US on two occasions, and would purchase more, however, I find it really hard to locate washed embryos in the US. Right now, I have embryos from two flushes sitting at an AI stud in the US to be shipped to Canada in a shipment of semen. This is how we ship most of our embryos, that is, we piggy back them in a shipment of semen to an AI stud in a country, as it greatly reduces the costs involved.Once they are cleared by the officials of a country, they are then shipped to where ever the buyer wishes them to be stored.. just the same as semen would be shipped.
Another of the really dumb rules is that the semen used in a flush, is supposed to be exportable to the country to which the embryos are going too. If washed embryos are disease free, what does it matter if the semen used is exportable? I have used semen that was not qualified for export, on occasion and just shown it as being US or EU ( European Union) qualified on the line that asks for semen qualifications. I have had no problems shipping internationally.
Here is another really dumb rule. If I want to use an American sire in a flush, the sire must have exportable semen to Canada. Most US breeders do not collect Canadian qualified semen as it requires the sire to be kept in stud for an extended period of time, usually between 45 - 60 days. ( It is the same thing if we want to collect US qualified semen).If the semen is not qualified to come into Canada, it is not possible to import it and breed the donor with it. It is legal, however, for a person to take your donor across the border into the US, breed her with the semen and bring her back home and then flush her a week later. I have done this on two occasions. I simply had the semen shipped to a friend who lives just across the border from me in N Dakota, I hauled the donor down the morning she was in heat, brought her home the same day, and then flushed her 7 days later, Both flushes were successful. This is now complicated by the added requirements of having to tattoo or brand any Canadian animals entering the US,but if you want to go through all the hoops, it is still possible.
I am hopeful that some of these regulations regarding certification by AETS and AIETS will some day be relaxed, however this may be just a dream. Vets are highly protective of many things they do. Here in Canada, they have even tried to regulate who can sell animal products such as worming products such as Ivomec, and many other farm products. They have not been successful in doing so, but they bring this up and try it again every few years.
