Rabbit kits born with violent shaking

First I would like to say that we have no vet anywhere near us, that will treat rabbits, so getting them diagnosed and treated professionally was not an option.

In a litter of 7 kits, born to a new dam and sire, two of them had varying levels of a near-constant shake. The shake was first noticed when they were six days old.

The shake ranged from a slight wobble, to a violent up-and-down convulsion. There was no head tilt. The babies would try to walk, with some success. Stress would make the shaking worse.

By the time we gave up on fixing it, the shaking was so strong that I would restrain their heads when moving them, to avoid stressing the neck. They were put down as a mercy.

Unfortunately I have no video, because I didn't have the heart to leave them shaking like that on a table.

We tried supplementing with vitamin B, with no result. The dam is freely fed on balanced pellets and grass hay.

The rest of the litter are now out and about, active, friendly and healthy.

The dam is a daughter of my old favorite doe, the sire is entirely new blood.

If you need any questions, I will do my best to answer. My primary concern is determining the cause, steps I can take to prevent it, and whether or not the problem came from the parents.
 
I have never seen or heard of this. My guess is that it is a congenital abnormality. If I were you, I would repeat the breeding. If kits in the next litter show this, do not use the parents for breeding again. I wouldn't save any of the littermates either.

This is my current plan, pretty much. None of the litter are being sold, because we sell for breeding stock and 4-H and neither would be ethical, if there is any chance that they carry the problem. As for breeding... well the doe was a one time breeder, she revealed major personality issues while pregnant, and I don't like a mama cowering in the corner during health checks </3

The buck however, I'd like to cross with my new harlequin doe... Fingers crossed the problem didn't come from him.

Unfortunately, if the problem is genetic in origin, it is most likely carried by both parents.

If the parents themselves do not have the problem, but it does appear in their offspring, that sounds like a recessive gene-- which only shows effects when a baby inherits it from both parents.

So that is bad news for the buck, if you were hoping to continue using him. If you breed him to a different doe, and no bunnies show problems, half of them would still carry whatever gene he has. That is not a problem if you butcher them for meat, but probably not what you want to sell for breeding stock.

But if the problem is actually caused by something nutritional or something in the environment, those bunnies might have been extra-susceptible (which is not really a trait you want to breed either), but it is not as strong a reason to avoid using the buck in future.

And if this was just a one-time oddity that never happens again, then it is puzzling but odd things do happen on occasion :idunno

This is extremely helpful, thank you so much! This is the information I have been really hoping to find in the five-ish weeks of frantic googling.

I'll breed him back to the original doe, to test for that. We've got plenty of time before our little harlequin is old enough <3

Thank you again!
