New photo of some Tauros bulls

Geer vanne Smeed published a new photo of four Tauros bulls at Kempen~Broek on

Anyone can guess what kind of breeds or crossbreeds these bulls are and it is probably impossible to find out with the information given in the web, but I speculate that the lying bull at the right might be a pure Maronesa, the bull left to it a Maronesa crossbreed, the bull right in the back a Maremmana crossbreed and no idea on the last one. 

EDIT: Geer vanne Smeed told me that according to his opinion the crossbred bulls might be Limia x Maremmana, Maremmana x Maronesa and Maronesa x Limia as those were the breeds present in the herd during the last years 

As to the looks of the bulls, the colour is flawless in all individuals. The body shape of the bulls in the foreground cannot be determined as they are lying on the ground, but all of them seem to have a hump and are not that bulky. They might not be quite as large and long-legged as average Taurus bulls, but it is clear from the photos that they are more aurochs-like than classic Heck bulls (such as this one in Vielank, for comparison). As the Tauros Programme and the Auerrind project are cooperating now, future generations might obtain the genes for really large-sized and large-horned animals thanks to Chianina and Watussi-influence. 
I especially love the head and horns of the putative Maronesa bull in the front. The horn curvature is identical to some European aurochs skulls (mind that those only show the horn cores, so that the horn sheath would make them longer and more pronounced in life, i.e. the horns of the bulls are still a little shorter and less curved than in an aurochs), and the snout is not as shortened as usual in Maronesa and still longer than in many Heck bulls.

Auerrind update

It has been long ago that I published my last post, and a lot happened. Especially the Auerrind project had some important achievements in the meantime: 

Cooperation between the Auerrind project and the Stichting Taurus 

Claus Kropp announced in April 2018 that the Auerrind project and the Stichting Taurus, which is responsible for the Tauros programme, are going to cooperate. The cooperation will include: 
- Exchange of suitable crossbred individuals 
- Sharing of research results 
- Conservation of the founding breeds 

Especially the exchange of suitable crossbred individuals sounds promising and it could result in a mutual benefit for both projects. The Tauros Project could finally get genes for truly large body size or horn size by acquiring Chianina or Watussi influenced Auerrind individuals, and the Auerrind project could get genes for decently inwards-facing horns via Maronesa-influenced Tauros individuals. 
I see the exchange of individuals as a middle-term perspective, as both projects are in a comparably early phase of crossbreeding yet. 

Incorporation of the Auerrind project into Rewilding Europe 

In May 2018 it was announced that the Auerrind project is going to join the network of Rewilding Europe. This will probably greatly help the project to acquire more suitable areas for their herds and increase volume of the project. 

New photos of the first-generation offspring

The herd in Lorsch has three healthy Sayaguesa x Chianina calves, two cows and one male. I think this is magnificent; as both the Chianina and Sayaguesa of the Auerrind project are of excellent physique and have good horn shapes, true F2 of this combination have the potential to result in very large, well-shaped and correctly coloured animals with good (albeit not very large) horns.

The Sayaguesa x Maremmana bull calf seems to develop a wildtype colouration, it will be interesting to see how its horns are going to get.

The young Maremmana x Watussi cow has a perfect, shiny reddish aurochs colouration. The horns will probably end up in an upright position because of the breed combination, but that can be fixed in future generations. It is interesting how the combination of the allele(s) for the wildtype distribution of the black pigment, contributed by Maremmana, and those for the production of red pigment, contributed from Watussi, resulted in a perfect wildtype colour phenotype.

The young Sayaguesa x Hungarian Grey cow is now old enough to show its final colouration and also how its horns will get. All in all it resembles me of some Tauros and Taurus cows, which is what I predicted because of the breed combination. It is interesting that the alleles for red pigmentation of Sayaguesa are seemingly less dominant than those of Watussi, as also the grown Sayaguesa x Chianina cows show a reduced red pigmentation.

The Sayaguesa x Watussi bull now shows its final coloration and it is perfectly aurochs-like. Body and head shape seem to reveal the Watussi influence but it has no fleshy hump and the dewlap is not that long. It will be very interesting to see it fully grown, especially because of the horns. Actually, this is the offspring that I was most excited on because I have the suspicion that this bull bred to the three Sayaguesa again might result, with a bit of luck, in one of the best breeding-back individuals born yet in terms of overall impression. This is for the simple fact that the Sayaguesa of the project are very, very good and a considerable increase of horn volume would turn them into animals pretty close to the goal. Thus I really hope the project gives 75% Sayaguesa 25% Watussi a try.
