I've no connections with sussex beasts, but really don't like what's happened to several native breeds I am involved with.Looking at it from the 'outside 'of the Sussex World I though that would be a good combination to have , the temperament of Sussex, the growth if lim , the milk of Sussex, ect ect , complement each other well , as opposes to the extremes of each breed !
AA and the black Galloways come to mind.
Why take something with such specific traits- esp Galloways- and change the breed into something completely different?
If there's breeds already providing different traits, go to it.
I now completely get what Joe Henson was doing, 50 years ago.
The SD's are a good case in point, They were a dual purpose breed, but that world -in the Uk has ended, so they moved away from milk.
