If you read my post earlier in this thread, you can see my experience is much different than other people who have posted. In 10 years of breeding purebred and crossbred white parks to red limousin bulls, we never had a speckled calf. We had solid black, solid red, or White parks colored calves. With hereford, it was 50 percent red or black white face and 50 percent white parks. With the black angus, it was 50 percent solid black, 50 percent white parks, a few with some small black spots. I have not had any line back or spotted or speckled calves out of the angus bulls and white parks cows. The two breeds that throw about 50 percent speckled calves are the jersey bull and the brangus bull. Alot of the spotted and speckled cows I have seen have got some ear, coming from a brangus. In the posted pics, alot of the spotted animals have some ear, also. With purebred or registered white parks, you can get a solid black or solid red or spotted cow once in awhile. Out of 150 purebred white parks, I have 5 solid black cows, 1 red cow, 2 black and white spotted cows, a couple with a blueish look, and one reddish looking cow. I have 6 crossbreeds that are speckled and they all have some brangus in them. My other crossbreeds are standard white parks marked except for the 1/2 jersey heifers that are white with brown ears, black, brown, or speckled---kind of a rainbow out of the jersey. My answer to Taurus is that in the case of using angus, limo, charolais, or hereford, I have not seen a speckled calf out of any of those solid breeds.
