Our commercial beef herd is made up of Angus x Friesian, Hereford x Friesian, Blue Greys (Galloway x Whitebred Shorthorn), British Blue x Friesian and next crosses (to Angus, Hereford and Red Devon) from those. Our homebred Jersey crosses will join the others when they are old enough.
The 1/2 or 1/4 dairy cow component gives plenty of milk and cows with good-sized pelvises, so we find this works for us better than pure beef cows.
The Blue Greys are on the moorland-type ground, wintered outdoors, with minimal input - just mineral licks and a scattering of hay in winter. The others are on upland rough pasture and most are wintered indoors on silage. A few will be wintered out each year on sheltered rough pasture with licks and silage.
Our own bull is an Angus, a very hardy type one, and we also use AI, usually British Blue, Hereford or Red Devon depending on the cow.
