Its basically something to do with the mare's blood type. her colostrum can cause the destruction of red blood cells and kill the foal. they say not to let the foal nurse for 48 hours. You would need a milk replacement (like powdered foal milk) and an antibiotic for the foal as well a s a muzzle to prevent nursing and to milk the mare and discard the colostrum. Im attaching links that talks about it.

If you do breed this mare Don't let the foal nurse. You could degrees the chances of an issue with it if you blood type the mare and stud. If they are a match it may not cause NI? IDK I would consult a vet if you did decide to breed her. I would avaoid it if i could though.

I'm well aware of what it is and what has to be done;I was wondering more about other people's experiences with it;whether they thought it was worth the extra work and caution that needs to be taken,if they had learned any tricks along the way,that sort of thing. :) The mare in question is a very well bred,seasoned broodmare who throws awesome foals.I have the opportunity to get her for a screaming deal,and she fits into my breeding program.But I've never had to deal with an NI mare before,and when questioning others and researching,have been getting mixed feedback.So,was just curious as to whether anyone on here has dealt with it before and what their opinion would be..

I have yet to read the link but my first question would be can she pass this on to any offspring? If so what are the chances of one having the same problem?
If the answer was yes to the first question and more than a small chance in the second one I would not have this mare in my program.
There is enough risk involved with a normal foaling . Seems like a lot of trouble unless the mare was very exceptional in every way.
Not many people have the time or knowledge to deal with a hungry foal and frantic mare for 48 hours.
I would also think the mare foal bond may not form properly. Shalom

Thanks for everyone's input.After putting some more thought into the matter,I've decided that foaling this mare out would be way more work and hassle then I want to deal with at this time,plus all the added expenses..There is a solution to prevent the foal from becoming sick,but it is a lot of work and very time consuming.She may be a great mare who throws great offspring,but there's other great mares out there;I'd rather keep saving my money and wait for a mare that does not have this issue.

Oh,and to answer your questions,dbararabians,it can not be passed on to offspring,and people who have dealt with it say it does not usually effect the mare/foal bond.

I haven't had a lot of experience with it but I know at my school (Colorado State) I have seen a few foals around having muzzles on because if it. They look like Hannibal lol.

I'm no expert but from what I recall you only have to worry about it while the dam is still producing colostrum. After she is done with that the foal can nurse safely. They can test the mare beforehand and use colostrum from a "safe" mare or a milk replacement temporarily.

I would consider this mare for my breeding program since she cannot pass this on to her foals.
However I would have to ensure 24 hour foal watch and the first 48 to keep the foal from nursing. That would increase the expense of any foal and would have to be considered into the cost.
That alone might not make the mare a good purchase unless she was foaling out champion after champion.
OP I agree save your money and buy a mare without this issue. Shalolm
