Subject: [Jacob-list] lilacs
I believe that it is a dangerous generalization to say that a lilac =
"Jacob" is proof of its purity. We have various shades of "lilac" in =
our Jacob x Horned Dorset sheep. The most common shade that I have seen =
in our crosses is the beige or taupe shade. Some of the crosses appear =
to have black spotting when lambs, and later on fade to lilac. Anyone =
purchasing lambs at auction and relying on the lilac shade to denote =
purity is taking a big risk.
It would be helpful for an "official" distinction to be made among the =
various recessive colors. Lilac does not accurately describe the =
chocolate or beige spotting. I would like to see our application for =
registration have chocolate and beige added to the black and lilac =
categories, then the number of recessive colored sheep recorded, as well =
as the number of blue eyed sheep.
