My mother and I just bought this stallion and we are not sure what bloodlines would be the best cross for him. We had an offer to buy him sight unseen, so we think he is something special, but we are not sure.
Please tell me what you think, because we have no idea if he has good bloodlines or not. We just bought him because the price was right and he has the sweetest disposition.
Here is his pedigree http://www.allbreedpedigree.com/el+rashiid+ma
Thank you for any information that you can give me.

Knowing not a lot about blood lines but a lot about genetics and the effects of inbreeding I would say only use this horse to outcross to anything with out Nazeer lines. For my likings he is way too inbred, one stallion, Nazeer crops up six times in 5 generations another three times in six generations and is a son of Nazeer plus there is another son of Nazeer that crops up twice in the five generations.
But I am sure there will be those who disagree.

Inbreeding results in loss of genetic diversity and reinforcing of traits. Loss of genetic diversity results in a less healthy animal. Out crossing results in hybrid vigor due to a more random / wider distribution of alleles. Just think how healthy the mongrel dogs of yesterday and moggies of today are.
Reinforcing of traits by line breeding can have its advantages when carried out judiciously. Unfortunately and particularly in the showing world, dogs, cats, horses etc, what tends to happen is that people set rules and fashions/ trends then end up dictating what people are breeding for.
Just look at the TB if you want to see what goes wrong in breeding systems where you select only for one thing, breeding the fastest to the fastest with no regard for confirmation. Hence we see in the TB world horses with poor foot confirmation breeding from horses with dodgy temperaments etc all of which are highly heritable.
The main problem of inbreeding is that while yes it will result in the offspring looking more like here parents and hence if those are the winning looks you are more likely to have a winning offspring. The down side is that any slight defect in any of the parents who crop up multiple times will also be magnified be that weak tendons a susceptibility to laminitis / navicular poor fertility.
Poor fertility rates are also linked to loss of genetic diversity as well as many other things. I can not remember why now but suspect that genetic imprinting has something to do with it, given that is the area of genetics I used to work in. Morbidity and mortality rates are also increased in less genetically diverse populations again this will be due to concentration of 'harmful' genes. Please not harmful genes may also be helpful genes. Cystic Fibrosis and Sickle cell anemia re examples of this, when a single copy is present they have a beneficial affect but when two copies are present they are harmful.
However most gene expression is multi factorial, so again one parent cropping up multiple time will reduce the variety in these multi factorial genes again increasing the likely hood of any less good copies of a gene being perpertrated and more likely to be present in both copies.
Hope that is not too garbled and makes sense could go on but feel this is getting a bit long.

Hi,
Most of that makes sense to me, thanks for that.

Hi All, the irony is that, for a modern Straight Egyptian, this stallion exhibits a reasonably broadbased pedigree!
He combines multiple Nazeer with two strands of Babson Egyptian and a cross to the Inshass line to Sameh. Not contradicting the genetic facts at all but nonetheless Straight Egyptian breeders have been working with pedigrees as limited and more so than this and the results are not all disasters - I think this newcomer should try and get some specialist feedback from a knowledgeable Straight Egyptian expert before making any practical decisions about how to breed with the horse.
Might I suggest starting a new thread titled as a request for "info on Straight Egyptian breeding please" or some such. If you like this horse, the chances are you are going to like other Egyptian Arabians too. Alexia |
