About Celtic Sires

Celtic Sires is a specialist stud providing the very best Beef Simmental and Dairy Fleckvieh semen.


Beef Simmental semen, primarily from our owned bulls, is sold to top breeders throughout the EU.


Dairy Fleckvieh semen is sold in the Republic of Ireland, where we are exclusive agents for all Austrian Fleckvieh semen.


Based in Ireland, we focus on cattle suitable for grass based systems. Our emphasis is on optimising output per hectare from a grass based diet.


Because we focus on one breed only, we study the bloodlines extremely carefully, selecting only bulls which have deep pedigrees, as well as current high indexes.


Our family has been breeding pedigree cattle since the 1920’s, and we are still farming with pedigree cattle on a daily basis.


We are always available for detailed personal advise and views – and we are always honest and open in our views on how each of our bulls are performing.
