Busy days at the university, so I do not have the time to write long posts at the moment. Therefore only a teaser today. A post collecting and analyzing primary references on western wild horses is in preparation, as much as one on the Sayaguesa and Tudanca at the Veluwe in the Netherlands. A post on historic Heck cattle, including the extinct Berlin lineage, is completed already, but the illustrations are not ready yet. I also plan to do a well-pictured post on the social and reproductive behaviour of cattle. My most extensive posts will be a series on the role of dedomestication in restoring "wild" horses and cattle.
Please stay tuned!
"Breeding-back" aims to restore or immitate extinct animals by selective breeding. This blog provides general information, the facts behind myths and news from various projects.

Newborn calf at the Lippeaue
UPDATE: Part of the numbers in this post were wrong, they should be correct now.
OK, there are probably numerous calves that get born in the population counting approx. 90 animals at the Lippeaue per year. But I report this one because it is of an interesting combination.
See here for the bull calf
This bull calf was born in a recently formed herd at Kleiberg, which counts 5 adult and subadult individuals yet. Her mother is one of the first cross animals of Taurus cattle, a 13 years old Chianina x Heck cow named Ludovica, fullblood sister of the bull Luca. The breeding bull is named Linnet, son of a pure Sayaguesa bull and a 37,5% Heck, 50% Sayaguesa and 12,5% Chianina cow (not a half-Sayaguesa though) - and therefore the bull is 18,75% Heck, 75% Sayaguesa and 6,25% Chianina and of the fourth cross generation. There are no photos of Linnet as an adult bull on the web, and I did not see him personally, but I saw him in a video on German TV, and he looked a bit like a larger version of a Lidia bull with thicker horns to me. The snout wasn't that long though.
Why am I mentioning that calf? It is a fift-generation calf - there are surely much more - and I am curious on how that bull will work out. This calf is a 34,725% Heck, 37,5% Sayaguesa and 28,125% combination. Inheritance works by chance, but his father looks very good, and the half-Chianina mother is able to pass on a full Chianina chromosome set, so I hope this bull might become an even larger but still nicely aurochs-like bull. And if not this one, another calf of these parents might. It looks like it has no apparent dilution expressed, so its coat should become good (it still might develop a light saddle).
UPDATE#2: That's what the bull looks like today.

Video of the feral cattle on New Zealand
New Zealand has a population of cattle that have been living feral there since the 1920s, descending from ordinary farm cattle. They are another example of how the body shape and proportions of cattle get changed by the environment and natural selection, creating an optical resemblance to the aurochs - let alone their ability to survive hindrances such as diseases, weather, injuries and of course the display of their natural instincts. Those cattle's proportions and body conformation strongly reminds me of Lidia, and therefore resembles the aurochs. Some of them also have aurochs-like coat colours. Their horns are not special though.
Here I found a video on the hunting of these cattle. If you can put up with the portrayal of the perverted joy and pride about needless cruelty against animals, you' probably enjoy the shots of these free-ranging feral cattle.

Post #100! And: Is there a difference between effigy breeds and landraces?
This is my
hundredth post on the breeding-back blog, and I am really happy how my blog has
been growing – last week I cracked the 500 mark for views per day, and it seems
that my blog is the second among the top Google results for “breeding back”
already. Thanks a lot to my awesome
readers!!
I spent the
last day clearing up older posts by correcting language mistakes, removing dead
picture links and inserting a few updates.
Moving back
to the topic, the question in the caption. As usual, I define an “effigy breed”
as the result of breeding for the desired traits of the extinct animal you want
to optically recreate à effigy breeding, a term I transferred from
German Abbildzüchtung as a neutral
alternative to “breeding back”. I often
thought about whether it is useful to make a sharp distinction between an
effigy breed and a primitive landrace, and if we should consider an effigy
breed “artificially/secondarily primitive” and a landrace “originally/primarily
primitive” (note that by “primitive” I mean less-derived in a value-free sense.
I am not happy with that term though, but I haven’t found a useful alternative
yet). The arguments for such a distinction are
1) effigy
breeds are aurochs-like or wild horse-like because they have been crossed and
selected for uniting as much wanted traits as possible, while primitive
landraces apparently remained in this state of primitiveness since the
beginning of their domestication and therefore their resemblance with their wild
types is the legacy of nature instead of artificial selection.
2) some effigy
breeds/lineages are selectively breed for increasing the size of certain features
without crossing by selecting within the breed only, for example large horns or
long legs and snouts in some Heck cattle lineages, large horns in Watussi and
large body size in Chianina. This might suggest that these traits should be
considered secondarily primitive.
If that’s the
case, what difference would it make, and are uncrossed primitive landraces more
desirable than effigy breeds? I think this is a totally subjective question and
everybody is free to form his own opinion, but I see problems with these two
hypotheses outlined above.
1)
Domestication is a process consisting exclusively of crossing and selecting
over thousands of years. There are, above a certain level, no consistent
lineages with a consistent set of features and purebreeding is a relatively
recent phenomenon of the last few centuries. Phenotypic traits get transferred,
altered or lost all over the phylogenetic tree of the domestic trait of a
species (as long there are no isolated subclades). This explains why some
cattle of central European dairy breeds like Braunvieh or Fleckvieh can show
the upright, lyre-shaped horns of steppe cattle and zebus but also,
surprisingly, horns with a perfectly aurochs-like shape. Or the
Murnau-Werdenfelser, a central European dairy breed as well, is a
morphologically unspectacular breed but yet has a quite aurochs-like coat
colour. Each cattle breed has a history of being a mosaic of its neighbouring
conspecifics, depending on how large the area of exchange and how intensive
this exchange is.
The history
of most Iberian primitive cattle is seemingly not very well-documented, but it
is in some Italian and eastern European breeds. And it shows that aurochs-like
landraces are no exception from having an origin of crossing and selecting and
introgression of breeds differing to a varying extent. For
example, Podolica was influenced by Braunvieh, Chianina, Romagnola, Maremmana,
Simmentaler and other breeds during the 20th century. Boskarin from
Croatia is a mix of Podolica, Maremmana, Chianina and others. Many of the small
Italian aurochs-coloured breeds apparently are mixes of local landraces and
Braunvieh-type cattle, just as many eastern European cattle breeds such as the
Rhodopian shorthorn or Busha. Pisano looks quite aurochs-like with their
primitive colour, the long legs and their – in some cases – aurochs-like trunk.
If it was an Iberian breed with an undocumented history, an advocate of the
distinction of original and artificial primitiveness probably would propose
that this breed and its ancestors always possessed these features in this
combination, and if their level of optic primitiveness had changed it more
likely decreased rather than increased. However, we know that Pisano is a mix
of Chianina, Braunvieh and Tuscan cattle – and since none of the breeds above
has a slender, long-legged stature with an aurochs-like colour at the same
time, it must be considered artificially primitive because it is the result of
crossing and selection, just like f.e. Taurus cattle would be tagged this way.
Whether it was the intention to breed aurochs-like cattle or not is irrelevant
for the genetic make-up of the cattle and plays no role. The only thing the
“genes care about” is whether or not the breeder selects for, say, long legs,
or not and not what his intention behind is. There are more examples for this,
like Sardo Bruna, and I bet that if we’d know more about the breeding history
of the Iberian primitive breeds, we’d rub our eyes how many examples there are.
Look at this Sayaguesa cow used in Tauros Project. It has a reddish brown back
like an aurochs cow would have, while most other modern Sayaguesa cows are very
dark brown to black all over their body. You might think we are looking at a
case of a cow with a remaining sexual dichromatism that wasn’t diminished by
selection yet, but in fact this cow is 25% Alistana-Sanabresa. Does that make
this cow less aurochs-like? If we wouldn’t know, we wouldn’t even think that
there is a difference. Another example: imagine Barrosa and Sayaguesa already existed
300 years ago, but not Maronesa. Some breeders had the idea to crossbreed these
two for whatever reason, and the result after some selection is a new breed
with horns intermediary between these two, sexual dichromatism (we know thanks
to Taurus cattle that sexual dichromatism can surface in crosses between wildtype-coloured
breeds of different tones), a short snout and comparably small body size. After
a few genetic bottlenecks that always can occur, the modern Maronesa phenotype
would have occurred. This is just an imaginary scenario and very likely totally
incorrect, but considering that the creation of a new breed always is the
mixing of other breeds, and that there is no reason to believe that there was
less exchange between the breeders than in similarly civilized regions of
Europe, we have to assume that each primitive breed is originally a mix from
other more or less primitive breeds. The same goes for horses of course. And it
is simply obvious that coincidental combinations of certain primitive breeds
can result in cattle or horses that are either a) as much as, b) less or c) more
like their ancestors in appearance than the founding breeds themselves. See the
Barrosa-Sayaguesa example, or a mix of Maremmana-Pajuna. Whether it is a, b or
c depends on the (coincidental) selection or bottlenecks as well of course. As
an example, I wouldn’t be surprised if the very long snouts of some female Sayaguesa
and perhaps some Pajuna are the results of in-crossing of Holstein-Frisian,
which increasingly take place.
Furthermore,
it is important to note that some wildtype traits simply cannot be reinvented
just by selection. While this is true for quantitative traits like horn size,
body size or leg length (which are influenced by environmental factors as
well), it is simply impossible for certain colour aspects. Wild type base
colour (E+) simply does not reappear in a population that doesn’t have it just
because one “tries” to select for it somehow. It has to be present and become fixed,
and it stays the same allele as in the founding breeds you got it from. You
can’t “create” dun horses either. So a wholly aurochs-like or wild horse-like
colour in an effigy breed that is the result of crossbreeding and selection is
as authentic as in a primitive landrace, which itself was very likely originally
a stabilized mix, and there is no evidence that all ancestors of that landrace
always possessed the same colour setting.
2) It gets
more complicated in features such as horn size and curvature, leg length or body
or hump size – these traits probably are the result of the interaction of many
genes we can’t track down yet, and are influenced by environmental factors and
phenotypic plasticity as well. But what
we can say is that if you cross a large-horned with an aurochs-coloured breed
and unite those traits in one herd, both the features are not anymore
artificial than those of its founding breeds, because they passed on exactly
the same genes to this herd. And whether or not the genes responsible for large
horns are the same as in the aurochs we just can’t tell. Therefore I use
“aurochs-like” instead of “primitive” when referring to phenotypic traits,
because the latter word automatically implicates that it is a unchanged,
genetically identical trait of the aurochs, which is baseless except in the
case of colour, while “aurochs-like” simply is more neutral.
Not to
forget, there are primitive southern landraces which were in fact selected for traits
unintentionally resembling those of the aurochs – such as Barrosa, which has
artificially large horns evidently created by selection within a population
without crossing in other large-horned breeds (just compare modern Barrosa with
those on that old photo UPDATE: I just realized that the link did not direct to an old photo of Barrosa cattle but to a Russian Death Metal song, sorry.). Does that make their large horns less
desirable for breeding-back? I don’t think so. It is the goal to create an
optical and functional imitation of the aurochs not only for fanciers and
education but in fact primarily for its function and value as a native animal
in natural areas, and nature does not care about such bagatelles we don’t even have
a convincing clue about.
To put it in a nutshell, I don’t think it is
useful to regard effigy breeds as artificially aurochs-like and landraces as
originally aurochs-like. After all, it sounds like an inconsequence in itself –
a product of crossing aurochs-like breeds and selecting them for uniting their
aurochs-like traits should be less original in the end? The history of modern
domestic breeds is very dynamic and so probably was that of their phenotype. Before
race breeding came up, farmers probably were very pragmatic and used those
animals accessible to them and selected them on traits they needed for certain
purposes. Either large udders for milk production, or a strong and large-humped
body for draft work. The history of many of the Iberian breeds is undocumented,
and that of Italian and neighbouring landraces shows that they are themselves
mixes of a several breeds, so we should assume that the Iberian cattle breeds
are of mixed origin like any other domestic breeds as well, and that their
phenotypic resemblance to the aurochs is mostly coincidental. As a consequence,
I don’t think that the aurochs-like phenotype of a good Taurus bull is less
original than the phenotype of an aurochs-like Pajuna.

Aurochs model WIP pt.II
As some of you might remember, I am working on two aurochs models, bull and cow, at the moment. Here's another WIP photo:
The bull model measures 19 cm at the "withers". It's based on the Braunschweig specimen and I am pretty happy with how it worked out. However, I am not sure if it might be actually too athletic. If any of you notices inaccuracies or imprecisions, I'd be grateful if you point it out to me, because after it is burnt I can hardly change it. I might do the dewlap a little longer between the forequarters.
After the first burning, I am going to add the tail tuft and - of course - the horns and the horns will be sticked into their place as well. The wire forming the base of the horns doesn't represent the final shape, by the way.

Taurus cattle in Hungary
I already
gave some basic information on the Taurus cattle in Hungary in this post, but in
the lack of recent photos showing what the current population looks like and
without more background information I didn’t have much to say. However, about three
weeks ago, I contacted Claudia Zimmermann and István Sándor
who are directly involved in the grazing project in the National park
Hortobagy, where the Taurus cattle are bred. They provided me with very helpful
information and a lot of beautiful photos, and I got permission to use them for
the blog and Wikipedia. Many thanks!
The grazing project was started with Przewalski horses
in 1997, for which the Puszta surely is an ideal habitat. Now they number about
250 individuals. One year later cattle were released, mostly Heck cattle from
Austria (more on Austrian Heck cattle in a future post), and Germany f.e.
Lippeaue, Wörth and Munich but also Neuwied and Karlsruhe. Steppe cattle and
Steppe cattle x Holstein were added because a large number of cattle was needed
for the large area of about 2500 ha (little less than half the Oostvaardersplassen). The total number of the cattle currently
is higher than 150, making it the largest population in a grazing project and
probably one of the largest herds of aurochs-like cattle of that quality in
Europe.
I was told that several bloodlines within the herd can
be distinguished that are respectively influenced by the following breeds:
Watussi, Taurus/Sayaguesa, Heck, Grey cattle and Holstein. As far as I know,
there are Lidia-influenced individuals as well. I suppose that these bloodlines
are not strictly separated and that the population is basically panmictic.
The horns of this Watussi-influenced cow may not be
that thick, but it might carry the genes for larger horns and there must be
Watussi-crosses with larger horns as well. I think this cow might be influenced
by Sayaguesa as well. What I find particularly interesting is the strong wine
red Watussi seems to add. Watussi is advantageous for its large horns and their
adaption to dry habitats. Using Watussi is often criticised because of their
half-zebuine nature, but Steppe-type cattle are massively zebu-influenced as
well and yet they were and are part of each aurochs effigy project.
The bull above is called Rimu (Grey x Watussi) x (Sayaguesa x Heck). He’s one of the largest bulls. The horns are quite
impressive and the colour is accurate, but his trunk is rather long and the
hump small. Would be interesting to see more results of such a combination.
The Holstein-influenced bull down below is called
Zeusz, I think he has a quite cool aspect:
The use of Holstein seems counteracting at first, but
it depends on how you select the offspring. The Holstein crosses tend to result
in rather large and long-legged animals. Both the black colour and the spots of
Holstein are dominant, so it shouldn’t be all too difficult to select those
traits out.
Now some
classic Taurus individuals:
Toldi (above) and
Szepes (middle) are fullblood brothers (75% Heck, 25% Sayaguesa). Toldi unfortunately
was slaughtered before reproduced because of his temperament, but Szepes is a
breeding bull and looks pretty good in my opinion (look at all the birds flying around him on the photos, like in Europe's old days!).
There is a
number of un-crossed Heck cattle in Hortobagy as well, including a bull from
the Insel Wörth herd. That bull is called “Anno” and used as a breeding-bull.
The Heck x
Gray cattle crosses are hard to distinguish from usual, not-well selected Heck
cattle (which are grossly influenced by Gray cattle anyway):
Phenotypically they
consequently are not convincing to me, but I think steppe cattle is advantageous
because it is a local landrace that is adapted to the Puszta, improving the
cattle’s suitability to the region. Furthermore, they are needed to build up
the quantity necessary for the ecologic landscaping. But of course Gray cattle
enlarges the portion of individuals having the dilution alleles that cause the
beige and gray colours we see in usual Heck cattle.
This cow is
an interesting animal:
What looks a bit like a usual Heck cow here is in fact a first-generation crossbreed of Holstein
x Gray cattle. I puzzled around a bit why this combination resulted in an
accurate aurochs colouration. Grey cattle is homozygous for E+, wildtype base
colour, while Holstein has Ed, black, which is dominant – so the cow actually
should be black. But perhaps the Holstein parent was E+//Ed and passed on the
wildtype allele. Grey cattle have a dilutor allele on their Agouti locus (at
least), resulting in their fawn colour, but perhaps Holstein has the wildtype
alleles allowing the production of red melanin, hidden under their solid black
colour. This is the only way I can explain this outcome.
Like the
Tauros Project would say, there has been a “breeding for quantity” phase, and
now the “breeding for quality” phase is about to start. They have a large
population, but numerous individuals do not show a satisfying phenotype yet. So
they want to produce a large number of young bulls and select the best ones to increase
the aurochs-likeness of the whole population. The selective process runs under
the goal of producing a complete aurochs effigy, and when I look at the
individuals on these photos, I think this is definitely feasible. The largest
bulls like Rimu and Zeusz measure up to 160 cm.
They have
all the aurochs features the Lippeaue population has, plus large horns thanks
to large-horned Hecks, Watussi and Grey cattle. Indeed their horns are obviously
larger on average than those of German Taurus cattle. In the reserve they are
going to select on hardiness and resistance to cold as well, so that the cattle
do not need supplementary feeding. The Heck cattle, Sayaguesa and a whole range
of other breeds proved that they cope very well with the circumstances of central
and western Europe, but the Puszta is a particular challenge for the cattle
because it is an exceptionally cold and dry area.
Previously,
supplementary food was given because the cattle calved during winter as well, what
is usually problematic for both cow and calf under natural circumstances. The
reproductive cycle of cattle adapts to that if exposed to natural selection,
but this is incompatible with the animal welfare for domestic animals (also in
grazing projects). So they separate the bulls from the cows for a part of the
year to prevent calves being born during winter for now, and also tend to
select out cows that calf during this season to mimic the natural selection.
2011 was the first winter the cattle spent without supplementary food.
The cattle
are legally classified as domestic animals, like in all other grazing projects,
and therefore have to be checked for certain bovine diseases like all cattle in
Europe (including those of Tauros Project or other grazing projects). I don’t
know if it is legally possible to treat them fully as wild animals (perhaps an
arrangement like in Oostvaardersplassen could be made), but I think it might
certainly be possible to let them breed freely after a sufficient accuracy of
the phenotype is reached. This would mean that we could expect similar
phenotypic changes concerning proportions, body conformation and horn shape
like in Oostvaardersplassen because of intraspecific fights (dominance of the
cows, reproductive success of the bulls etc.).
It is
really enchanting to see how really aurochs-like cattle are reconquering natural areas
around whole Europe, not just less than mediocre Heck cattle in Zoos. I am talking about all those Taurus cattle, Tauros cattle in three, soon four, areas, and now also the Uruz Project. As a last
photo, here is a herd of cows along some Prezwalski horses:

New photos of the Tauros Project on Rewilding Europe
Finally we get a sneak-peek on cattle of the Tauros Project we haven't seen before, like some second generation animals, but also of older individuals we are familiar with already.

This would be simply awesome, and certainly helpful for the Tauros Project's information flow.

What I - and I am sure a lot of other people too - really would like to see a document revealing all their crossbred animals (or at least the breed combinations that exist already) and qualitative photos showing what they look like, so that we know which crossbred animals we are looking at. This would be simply awesome, and certainly helpful for the Tauros Project's information flow.

Tudanca - grey, numerous and beautiful
The ABU
described the Tudanca as “small, but
displaying a lot of aurochs features” in their guidelines [1], and in my
opinion this is accurate. My very first aurochs reconstruction done by photo
manipulation was based on a Tudanca bull:
Modified Tudanca bull from Wikimedia Commons, horns of a Maronesa bull |
Wikipedia states
that Tudanca cows reach 135 cm at the shoulders and a weight of 320 kg, what
sounds plausible, and bulls 150 cm and 420 kg. The height of 150 cm is
plausible as well, but 420 kg are very likely too light for bulls with this
body conformation. For comparison, a Heck bull with 145 cm shoulder height
weights between 600 and 900 kg [2,3]. According to the DAD-IS (Domestic Animal
Diversity Information System), Tudanca grow 165 and 160 cm at the withers and 650
and 450 kg (male, female, respectively). The shoulder heights are likely
exaggerated, but the weight data sounds plausible.
Tudanca is
one of the very few aurochs-like breeds that is still numerous, counting 12.230
individuals in 2011 (DAD-IS). This is four times the number of Heck cattle. Tudanca
live in the Cantabria uplands, where they cope with a humid and cold climate.
The bulls
are not long-legged and therefore look heavy, and their snout is shortened. But
the have a well-developed hump and an S-shaped backline, and they have
prominent forelocks – a feature that I appreciate very much, it is historically
well-supported that European aurochs had them, and they give a kind of wild and
masculine appearance. The cows have longer legs, though their hump is not as
well-developed. The horns of Tudanca are comparably long, but their tips curve
outwards in a corkscrew-like manner, resembling those of some Maronesa cows. A
lot of Tudanca cows have horns facing strongly outwards, like a lyre pulled apart.
The colour of Tudanca lacks phaeomelanins and therefore is grey. The sexual
dimorphism is reduced, but bulls are darker than cows in general. Cows have a
prominent ocular ring, which is most likely is a juvenile feature.
The ABU
once did a Tudanca x Heck cross, but were not impressed by that combination. I
also think that Tudanca doesn’t add anything to Taurus cattle except more
undesired features. The breed, on the other hand, is used by the Tauros
Project. There are Highland x Tudanca cows (photo) covered by a Sayaguesa, and Sayaguesa
x Tudanca cows covered by a Limia (video).
Now, be
delighted by some nice photos of beautiful Tudancas:
