Twyning Ash

Set in 550 acres of grass and arable land it is a family run mixed farm consisting of beef, sheep and arable. Currently comprising of 550 head of cattle (approximately 230 beef cows and followers, which are Limousin cross British Blue or British Blue cross Limousin). The whole herd is a closed herd and has been since 1995.

“From day one we have always seen the importance of recorded figures and this philosophy hasn’t changed to this day making us the longest recording Blue Herd in the country. It has always been our goal to produce meadow quality bulls with easier calving ability and high growth rates, good mobility with length and height. In the 23 years we have been selling semen we have earned a reputation within the AI industry with dairy farmers producing the cross bred calf that the commercial beef producer demands”. (Richard Carter, Twyning Ash)
