Kathie in Thorp":hrk6stzj said:I'll make this question short -- Do the major semen suppliers in the USA require a check for the translocation gene -- for any translocation gene affecting fertility, no matter what prefix is attached to the name of it?
Kathie, the reason no one is answering that question is as follows in an orderly fasion:
1. It is a (1;29) Robertsoniam Translocation not a Translocation Gene as djinwa stated.
2. There are no federal or state regulations that specifically outline a list of genetic tests required for semen. There are hyigene requirements, handing requirements, AI technique requirements, etc. What djinwa stated was that bull was only tested because it was being exported. It would have potentially never been detected if someone had not requested export of the semen.
3. Major semen companies like the SS rep I talked to comply with NAAB and CSS requirements which do not provide a list of genetic anomalies to test for.
4. Kenley Conner told me they test for CA, NH, etc. Those are anomalies that have come to light in the last 10 years that have almost destoryed some angus breeders. But this is on a company by company basis as "good business".
5. There is a scientific reason you would not impose rigorous genetic testing reqirements on semen. It is an open field. Unless you are a student of genetics, it may be difficult to appreciate. But it would be like setting a target and continuously moving it.
