Videos of Tauros cattle

At the moment I do not have the time to write long posts with much literature reference, therefore another "short post" today. There are several videos of Tauros cattle out there, but since the official Tauros Program webpage doesn't present media of them you have to know where to look. In order to make you the quest easier, I'll post all videos of Tauros cattle, crosses as much as parental generation individuals (= pure cattle), down below.



Videos © Theo van der Heijden. The upper three videos show Maremmana x Highland cows, a Sayaguesa bull (UPDATE: Limia bull) + their F2 offspring, the two videos in the middle show Pajuna, Sayaguesa and Maremmana, and the lowermost two videos show a herd of pure Sayaguesa (UPDATE: The lowermost video in fact shows Sayaguesa x Tudanca cows and a Limia bull). 



Video by European Wildlife. It's the oldest Maremmana x Pajuna cross bull named Manolo Uno. 

I was especially curious on the (Maremmana x Highland) x Sayaguesa offspring. Those among them which are phenotypically wild type coloured are all very dark, so reduced sexual dimorphism, which is probably caused by Sayaguesa. However, this can be fixed in the next generation. I am curious on how the horns of these animals will grow. The screenshots below, taken from the videos by Theo van der Heijden on Youtube, show the Sayaguesa bull and the oldest F2 bull. Since the video was made in February 2013, I am looking forward to see how it looks today.

  1. Am I wrong to think all those highland cattle have no business out there as part of this project? I think it is going to set the project back years trying to breed out all the bad highland traits the initial crosses will have. And if you insist on getting some of the "good" highland traits, why not just use some of the better heck cattle lineages in your initial crosses instead of highland?

    1. If they use the right F2 and cull the bad ones, there is the chance of limiting the unwanted Highland traits. But you are right, this breed introduces many undesired features and I already had the same thought you had; using good Hecks, or Ecolanders (which will be covered here in a future post), probably would have been more advantageous for the project than pure Highlands. But the reason why they wouldn't include Heck cattle or Heck-influenced cattle is more of an ideological than a practical reason.

  2. Regarding Highland cattle I agree completely, it's one of the least interesting breeds regarding any breeding back project. About Heck cattle they are definitely more interesting than Highland, not my first option but some of them quite interesting.
    Best regards

    1. Heck cattle is such a heterogenous breed that its value for breeding back varies greatly as well. Most Hecks are mediocre or ok, about as aurochs-like as an average Iberian breed like Alistana-Sanabresa or Mirandesa in sum, other herds are either horrible and totally not useful (I wrote a post on them too), and some herds, like the one in Wörth or good Taurus cattle, are indeed very aurochs-like, probably comparable to very aurochs-like Iberian breeds like Maronesa, Sayaguesa or Lidia. The semi-feral Hecks in the Netherlands (a post on them will come soon) and especially those at Oostvaardersplassen also have some valuable individuals because of the natural selection they have undergone.
