First question is NI - Neonatal Isocerythrolysis
more common in Mini's than large horses?
I have read all I can find and mini's are never mentioned. We had 6 cases of NI by 3 different stallions...I am at a total loss.
Please help, anyone..
thank you, Sally

I am not aware that NI is more common in miniatures, but do stand to be corrected in that area, as we do not deal with a lot of miniature horses. It is more common in mules.
How was the NI diagnosed in your foals? It is pretty rare, and it seems very strange that you would see that high a percentage.
- Were these foals from mares that had foaled before?
- Were they bred back to the same stallions as previously?
- Were there dystocias involved in previous foalings?
- Have you had the mares/stallions blood-typed?

One maiden mare but she foal received colustrum from another mare.
Vet tested and said NI on the foals
All bred to different stallions. Studs have had no other NI foals
Yes, dystocia in all previous foalings
Not blood typed yet.
I am thinking it is from the dystocia - somehow blood got crossed during foaling

The transfer of blood during a previous foaling is the most common mode of creation of antibodies, so that is the probably cause.
There is a good article on the subject to be found here (follow that link).
