In a previous post, I presented an aurochs reconstruction I did recently. I wrote that it matches 100% what I imagine a Holocene European aurochs to have looked like, and that there are obvious similarities to many Lidia bulls (Iberian fighting cattle). Of course there is the danger of a Pygmalion effect: I might draw my aurochs Lidia-like, because I consider Lidia aurochs-like. This cannot be ruled out completely. But I always try to follow the evidence and not to be guided by preconceptions when doing illustrations. In the post linked above, I explained why I drew the bull the way I did. Here is the illustration I am talking about:
Actually, the fact that Lidia is one of the least derived cattle breeds left today did not just come to my mind because of that drawing, but was apparent to me right from the beginning when I started to become interested in the aurochs. I use to explain the looks of the aurochs to people as “much like a big, long-legged and large-horned Iberian fighting bull”. Also, aurochs expert Cis van Vuure comes to the conclusion that this Iberian breed is the most aurochs-like breed in his 2005 book “Retracing the aurochs: History, morphology and ecology of an extinct wild ox”. And also Lutz Heck considered the breed very reminiscent of the extinct wild form and relied heavily on it in his breeding project (his lineage diminished, modern Heck cattle most likelyhas no influence from the Iberian fighting bull).
I am going to sum up the aurochs-like pro’s of Lidia cattle:
- Muscular, athletic body shape very reminiscent of wild bovines
- High processus spinosi in the shoulder region (“hump”), probably as large as in the aurochs
- Often elongated skull shape, straight to convex snout and often prominent forelocks, sometimes also on neck and face
- Horn shape reminiscent of that of the aurochs with an inwards curve, although usually not entirely as prominent as in the aurochs
- Short dewlap and scrota and small udders in less derived individuals
- Wildtype colour plus sexual dichromatism (albeit reduced) present in the breed
- Robust landrace, used to live outside with little husbandry all year round
Especially the first four points are very advantageous for “breeding-back”, as those traits are rarely found in any other primitive breeds to the same extent. All of them give primitive Lidia individuals a very aurochs-like appearance, and I am going to link some of those less-derived aurochs-like Lidia individuals here:
For a video of aurochs-like Lidia bulls, go here for example. Another video of bulls with an exquisite anatomy and also respectable horns is here.
It is not only their less-derived anatomy and looks that make Lidia special, but also their hardiness and independency. As I reported in 2013, the three Lidia cows in the German Lippeaue reserve were the only cattle that were never seen to make use of supplementary feeding.
Despite of their many advantages, this breed also has considerable disadvantages. First of all, Lidia are quite small cattle. According to the Domestic Animal Diversity Information System, bulls reach a withers height of 130cm, and cows 110, which is 10-15cm smaller than Heck cattle and almost half a meter smaller than an average Holocene European aurochs. But even more important, Lidia cattle are being bred for aggression and “fighting spirit” and consequently are very aggressive and nervous, difficult to handle and often attack easily. Additionally to these two major disadvantages, Lidia bulls also tend to be short-legged compared to aurochs.
But of course it is the task of crossbreeding and selection to eradicate such negative traits, just as too small horns or undesired colour schemes. This has been tried in the Lippeaue, where three pure Lidia cows have been used for breeding. But they were not really satisfied with the results. For once, the crossbreeds remained comparably small, even if they had portions of Chianina or Sayaguesa, two large breeds, in their genome. The crossbreeds also displayed overly nervous or aggressive behaviour. This goes for the half-Lidia bulls as much as those that were only quarter Lidia such as Latino. One half-Lidia bull was sold to Hortobagy, Larus (which looked quite good), and Istvan Sandor it was the most aggressive bull he ever experienced. Another half-Lidia bull was sold to Denmark and slaughtered because he was too difficult to handle. I had a look at many Lidia cross individuals in Matthias Scharf’s photo archive, and many of them did look more muscular than crossbreeds without Lidia, but they also tended to develop a rather elongated trunk and did not possess the slim athletic waist of pure Lidia. As a side note, even pure Lidia bulls often grow rather hefty at higher age, and the crossbreeds seemingly tended to go that direction right from the beginning. So crossing-in Lidia was not that successful as hoped, which is why the ABU diluted the influence of this breed in their herds, and Matthias Scharf even said that he considered most Lidia-crosses to be “small, ugly and mean”. Currently, they have one good half-Lidia cow in their herd that also has a comparably relaxed behaviour.
So does this mean that Lidia is, despite its obvious qualities, not a useful breed for “breeding-back”? The Tauros Programme, for example, will not use this breed, especially because of its behaviour. Considering the difficulties in handling Lidia crosses, and the disappointing looks of many of the cross results concerning size and body shape, I would say that Lidia is indeed perhaps not worth the effort in conventional crossbreeding and keeping them in grazing projects.
Nevertheless, I also think that it would be a shame not to make use of the potential that is in the breed. Maybe the crossbreeding results are too double-edged to speak of a “successful use” of this breed in crossbreeding, but perhaps a project working exclusively with good, useful individuals of that breed and trying to eradicate the negative traits of Fighting cattle would be fruitful. I am thinking of a project that would at first try to find a sufficient number of aurochs-like Lidia cattle such as those on the photos I linked above that have the right colour setting, an athletic body, elongate skulls and good horns, and trying to acquire individuals that are as large as possible, as long-legged as possible and perhaps not overly aggressive or nervous. For this, I would try to search breeding sites all over Spain and Portugal and also include the Casta-Navarra breed. Selecting them for couple of generations for the good traits and against the three undesirable Lidia traits (small size, short-leggedness, aggression/nervousness) might produce some good results. When selecting against their aggressive and nervous behaviour, I would try to pay attention to not domesticate them any further by selecting explicitly on tame and docile behaviour, as pleiotropic effects can affect other traits as well as we see in all domestic animals (see the Dedomestication series). The question is, then, how to handle the cattle. It would be very difficult to next to impossible to keep them like in grazing projects or private farms. It might be wisest to handle them just like other Lidia breeders do, or perhaps like American farmers keep their bison, also with the necessary equipment. After all, a true wild aurochs probably could not be handled much differently, and it is no coincidence either that most natural grazing projects work with cattle instead of wisent. Of course it would be more advantageous if their behaviour was suitable for grazing projects, as grazing projects provide the most abundant opportunities to spread the breed and keep the animals under semi-natural conditions in herds of sufficient size, but this post focuses only on a scheme to breed a very aurochs-like strain of Lidia and not how to spread it. If it is indeed possible to breed a more relaxed and less dangerous behaviour but maintaining the wild cattle-like body conformation, it would be pleasant of course and perhaps enable the use of these cattle in grazing projects. However, I think it is questionable if this is possible within a few generations as fighting cattle have been bred for aggression for dozens of generations.
The idea of establishing an aurochs-like cattle population using Iberian Fighting cattle only is not new. Lutz Heck considered this breed almost indistinguishable from the aurochs, so that it is surprising that he still bred with other breeds as well. Cis van Vuure also proposed a project working with the most primitive Lidia cattle only in order to achieve maximum resemblance to the aurochs. I also remember that in email conversations it was once considered to put such a project into practise, but as several years passed now and I discovered no mention of it on the web I assumed this idea has died a silent death.
Also, I have my doubt that it is possible to achieve all aurochs-like traits using Lidia only. While some Lidia grow larger than the norm, I would be very surprised if selective breeding is able to raise the size range from 130cm for bulls to 160cm at least within a couple of generations. The same goes for horn size – while Lidia are not small-horned, the largest horns of this breed are still only at the lower size range of aurochs horns, perhaps still a bit too small when considering the size of the horn sheath. Also, the breed might need a boost in leg length, even after selective breeding. Furthermore, the problem with breeding for quantitative traits is that it takes comparably long and other traits might get neglected, including also genetic diversity (Lidia is already inbred).
Thus, crossing-in breeds that might help to overcome these deficiencies and also to increase genetic diversity is suggestive. The first option that comes to my mind are Chianina or Maltese cattle that would add the large size, slender posture and long legs. Maltese cattle have the advantage of introducing colour dilution alleles to a lesser extent and having longer snouts, but are far less available, with not even hundred individuals and only on Malta. The big disadvantage both breeds have are the very small horns. The horn size of Lidia already has to be improved (although some individuals, like these young bulls, have comparably large horns), and crossing-in one of these breeds would introduce alleles for very small horns, and since horn size is probably controlled by several gene loci it would be even more difficult to breed for the desired horn size. So it would be advantageous to add another breed to increase horn volume. Which breed would be best to do this job? One idea would be very large-horned Texas Longhorn with the right colour setting. However, the disadvantage would be that they are small-sized as well and have very outwards-facing horns. Another possibility are large-horned Heck cattle from lineages with a comparably stable inheritance; their disadvantages are their very domestic, heavy body and paedomorphic skulls. Using Watussi would greatly increase horn size, but also introduce many undesired traits concerning body shape, dewlap, colour, fleshy hump, skull shape et cetera, which is why this breed would have to be used wisely and with patience. If one cannot decide among existing stable breeds which one to chose in order to increase horn size, one could wait for other projects that are already in progress now to produce results that can be used for this job. Such as the Auerrind project, which has just started and is using Watussi. Perhaps in 15 years, when also a Lidia project would see first results, there might already be good Watussi-influenced Auerrind cattle that could be used in order to increase horn size in an improved Lidia strain without introducing too many undesired traits. This is just brainstorming – in practice it depends on many factors of course.
I would not suggest to start crossbreeding right from the beginning and to a larger extent, otherwise I would not be talking about a Lidia project here. It is about preserving, concentrating and improving the aurochs-like traits present within the Lidia population, and using other breeds only after a phase of selection when selective breeding has been proven to not being able to reach body size, leg length and horn size to a desirable degree. Another positive side effect of crossing-in other breeds would be that at least some individuals might display a more relaxed behaviour. I would use other breeds only carefully and perhaps use only F1 crossbred individuals in order to not diminish the advantageous Lidia traits. The point at which I would start to make use of such crossbreeds is when selective breeding has been shown to not reach all traits to a desirable extent, which would be after a couple of generations and therefore about 15 years or so (which would equal about five generations).
How could such an aurochs-like Lidia strain be named? For Maremmana, some people like to speak of the optically less derived individuals or herds of “Maremmana primitiva”, although those Maremmana primitiva do not represent one gene pool or breeding line. In the case of this Lidia lineage, on the other side, it would be one population/lineage. So perhaps calling them “Lidia primitiva” would be an idea.
I think that such a Lidia project could achieve a high level of authenticity regarding looks and anatomy and perhaps also behaviour (yes, exaggerated aggression is not “natural” behaviour; but tameness and docility are not either; you certainly could not have used an aurochs for draft work or have milked them). There is also the chance that with selection against exaggerated aggression and crossing-in of other breeds Lidia primitiva might once have a behaviour that is suitable to be used in grazing projects and other aurochs projects.
This post is just a thought-experiment, but I hope that it inspires and perhaps other people have similar ideas in order to make use of the potential we find in Spanish fighting cattle.
