Today, Claus Kropp posted new photos of second-generation Auerrind calves. They are the offspring of Alvarez, the Sayaguesa x Watussi bull.

This photo shows a young (Sayaguesa x Watussi) x (Sayaguesa x Chianina) bull. His colour is flawless as he is black with a dorsal stripe. I think he looks promising, he is quarter Watussi but does not have any of the obvious negative Watussi traits (zebuine hump, long dewlap etc.). If his horns get good and he grows large, he will make a prime new breeding bull.  |

This photo shows a (Sayaguesa x Watussi) x Chianina cow calf. It seems that she will be of a correct cow colour, and thus not too dark (as both Sayaguesa and Watussi do not have sexual dichromatism, this is a strong hint for the suspicion that Chianina has sexual dichromatism masked beneath the colour dilutions). Based on her breed combination, she would be the ideal cow to mate with the young bull linked above, as the result would have the potential to not only have a qualitative phenotype but also to be homozygous for some of the desirable traits inherited from the three founding breeds.
Those look very promising indeed! If I ever visit Europe, I would love to visit (if possible) some of these projects.
ReplyDeleteThank you very much for the interesting information! Yes, the combination of Sayaguesa, Chianina and Watussi should have good phenotypic potential. Especially if Sayaguesa keeps a dominant influence, the suitability for southern and central European pasture projects should also be high. It will be exciting to see how the horns develop. At least in the F1 genus with Chianina influence, inwardly turned horn tips have probably not yet become established. This also applies to a very interesting F1 cross between Chianina and Cachena, which Felix Hohmeyer can show near Gütersloh. But maybe this will happen in later generations? I am curious how the Maremmana cattle used in the Auerrind project will affect the breeding progress? In the TaurOs project, the Maronesa cattle seem to have a favourable influence on the horn position? But here, too, we will probably only get clarity after further generations!
ReplyDeleteIt will be interesting to see how the combination represented in the bull calf compares to the 50% Sayaguesa, 25% Chiannina and 25% Heck combination that, according to the information on this blog, is often found in the Taurus cattle.
