We are currently very busy at GRS with a lot of donors on the centre.
The range of breeds includes Wagyu, Holsteins, Angus, Ayrshires and even some Scottish Highland cows with calves at foot.
We have been regularly sexing embryos from a number of Holstein cows with the ratio of males to females about 52:48 which is right on average but the results from individual donors varies enormously.
We have a number of Wagyu donors on the export centre, flushing mainly for China, but we are able to collect embryos for many other countries if required.
