Artificial Insemination and Embryo Transfer

February 2017 Update

Hans Fokker 95 has come back from AB Europe in Edinburgh after another session of semen collection. He has become popular and when his progeny is seen at sales and in breders Suffolk flocks one can be nothing but impressed with the very sound clean sheep which are outstanding examples of the Suffolk breed, have very clean legs and heads and impressive tight skins and great conformation.

Ewe lambs sired by him can be seen on the female sale page.

What is most impressive are his EBV’s. and a close study of his results on Basco are worth it. His most outstanding EBV is his muscularity, which after all is what sheep keeping is all about. Namely the production of meat. He has the highest proven muscle EBV of any ram and any breed of sheep in the UK which is currently 7.90mm for 274 progeny in four different flocks with an accuracy of 98%. He has had a dramatic effect in lifting the muscle EBV when used on poor or average muscle figures.

He is a very sound sheep and in his first three season has stopped all his ewes in the first cycle. His Sire Sandyknowe Ettrick 07-1, who was purchase by our Hans flock at Kelso for the then Kelso record price for a Suffolk shearling of £3000 was also a very fertile ram and worked naturally for 5 seasons. Fokkers dam T79:K14 is still in the flock and again in lamb and expecting her 8th crop. She is expecting a single and still looking well.

Fokker 85 CT scans are as follows:

July 2016 Update:

Hans Fokker 95  Pedigree number T79:13:095 has been used with AI by the AHDB Ram Compare Trial. As commercial ewes have been used to produce prime lambs whose slaughter details will be recorded and compared to other breeds in this trial.

This year one of his lambs, which was born (via AI) in John Key’s Midhope flock has had a muscle EBV of over 8mm.

Our March born Suffolk lambs have just been scanned and their muscle images were outstanding.

If you look at his AI progeny in the various flocks The Fokker has been used you will see that the improvement in muscle EBV’s have been outstanding Follow his progeny on Basco.

We have used Laproscopic Artificial Insemination since the late 1980’s and had generally satisfactory results. It is an excellent way of bringing new genetics into the flock and some of the very best males in the breed can be used.

We also exported embrioes to Australia.  This is an excellent way to trade superior genetics on a world wide basis while also keeping the risk of spreading diseases to an absolute minimum.

In the UK breeds like Texels and Suffolks have made great progress as the result of  sire reference schemes making use of AI using the same high indexed rams in numerous flocks in the same year and as a result benefitting from increased accuracy of evaluations

Does using a high index ram make a Difference

Large quantities of semen can be made available from the current Stock Sires retained in the flock.

Semen is currently in store from all the rams listed below.
