Le sexage des embryons
Embryo sexing on the farm
cases, the amplification of DNA does not always happen
strip is revealed, the sex of the embryo is therefore
impossible to be determined in any way. However, this
happens only in 3-4% of all cases.
if a strip
X appears alone, it is then identified as female, even
though, in some rare cases a male calf would be born.
This is caused by the fact that chromosomes Y are more
difficult to be revealed.
last two years, we have sexed about 1000 embryos. The
reliability of the results is 100% with males and over
97% for females. The gestation rate is over 60%.
this skill requires some specific and expensive
materials and products.. It takes also plenty of time (8
to 10 hours from the collection to the installation for
couple of years ago, a new specific freezing technique
for sexed embryos can now acquire a 60% successful
gestation rate after experiencing with about 60 frozen
then freeze the left-over female embryos after sexing
and also stock them up when there are not enough
recipients. They will be transferred as soon as new
heifer recipients are available.
