New photo of Alvarez the Auerrind bull

The Sayaguesa x Watussi bull is now subadult and Claus Kropp presented a recent photo:

As you see, it has a flawless colour, the horns seem to start to curve forwards and not as upwards as in Watussi, and the body shape is a bit better than in Watussi. It is as large or a little larger than its father and still growing. It will be very interesting what the final horn shape and size is going to be. 

Maybe the ideal breeding partner for this bull is Sayaguesa x Chianina (the bull will be moved to the herd with the cows of this combination soon). It is, of course, playing with luck how good the second-generation individual will look like. Alvarez might either pass on either the flawless colour, Sayaguesa-type body and large horns, or Watussi traits and Sayaguesa-type horn size et cetera, while the Sayaguesa x Chianina might either pass on the right colour or dilutions, small horns or the right horn curvature and colour and so on. Breeding works with luck. 
One method to reduce the amount of luck necessary would be to produce good F2 of the respective generations first. An F2 for Sayaguesa x Watussi should have many Sayaguesa traits but have large and thick horns, a F2 for Sayaguesa x China should have the right colour, right horn shape and be large, long-legged and slender. F2 would also be more stable on these traits than F1, which are not stable at all for genetic reasons. These good F2 could then be bred to each other in order to seize the maximum potential in this combination. This would, however, add one additional generation to the breeding, but I think it would be worth the effort. 

Anyway, a (Sayaguesa x Chianina) x (Sayaguesa x Watussi) has a high potential for uniting many aurochs traits, and if a sufficient number of individuals of this combination is produced, some might look superb.
