This bull is called "Linnet". It is half-Sayaguesa and half a mix of Sayaguesa, Chianina and Heck. In summ he is 75% Sayaguesa. Unfortunately his trunk seems to be a bit long for an advanced Taurus bull, but I like his muscular stature. Unfortunately he has a colour saddle. The horns are thick at the base and nicely curved, but they "stop to early", their tips would have to continue to grow in order to reach the right curvature.
This is a nameless son of Lamarck and this cow. Both are Sayaguesa x (Chianina x Heck) and fullblood siblings. Consequently, this son is a true F2 in the strict genetic sense and there is a chance that more the good features he has are homozygous than in its parents, respectively. Of course his two good-looking parents would also produce less good-looking animals. I really like this young bull - colour, horn size, hump and skull shape are very good. The horn curvature could be better, but I like the horns overall. Based on this photo I can't really judge its proportions. I was told that he isn't large unfortunately. He is a breeding bull at the moment.
Here is the genealogy of his ancestors and relatives. The bull at the top is a fullblood Heck called Lancelot, from the Neandertal. Its son Luca is half-Chianina. With a Sayaguesa cow (I assume it is the same mother, but there always were several Sayaguesa cows in the reserve) he produced the bulls in the middle, one of them being Lamarck. I don't know the full ancestry of Lamarcks son on the left, but I think it has much Sayaguesa in it.
Hi,
ReplyDeleteI think "Linnet" is a beatyfull bull, but his legs are a little bit too schort, his horns may be get longer when he is older. All the "breeding back cattles" have the failure of short legs.

Concerning your last sentence, I have to admit that you are wrong - there is a number of Taurus cattle and also Heck cattle that have the desired ratio between trunk length and leg length, and of course many primitive breeds do so as well.
DeleteHi,
ReplyDeletewhy use fullblood siplings? This is Inzest. All breeders of any mammals know that this is the wrong way. The genes are too relativ. One can get a beautyfull animal, but with no future.
I'm breeding fishes and birds all my live (i'm 58 and i breed fishes since more than 40 years, and birds i bred for 20 years) But it is no way to breed with sipplings. May be in a few I bred with oncles, but this i made carefull and look what the children are bee.
Not necessarily, line breeding is in fact common in breeding and if executed with care, it can be a very useful tool to get genetically stable animals. I don't suggest to build up the whole population upon sister matings (which would be practically very expensive btw), but to produce a number of homozygous animals that help to stabilize the traits of the population overall.
DeleteThat would probably the most sensible and practicable way.
