Embryo Transfer

[Anonymous]

Does anyone know if any studies have shown an increase in congenital defects resulting from the use of embryo transfer in any breed? <br>

<p>The American Simmental Association has been keeping tract of congenital defects in registered cows for years...I'm sure they have a study regarding which are natural breeding and which are from embyos.

Interesting question. I have been using ET for several years and now have one flush I can't get a cow to bring to term. They have all aborted at 7 months. I have no proof its congenital, but its too co-incidental. No other abortions have occured in the herd, or even from the same donor cow in other flushes.<p>Jason Trowbridge<br>Southern Angus Farms<br>Alberta Canada

: Does anyone know if any studies have shown an increase in congenital defects resulting from the use of embryo transfer in any breed? <p>Trans Ova Genetics has several offices here in the Midwest (and a website, listed below), perhaps they may have some information. I believe some of the early embryo transfer studies were done at Colorado State University (Dr. Peter Elsden ?) you may try there too.<p>Interesting good question.
