Subject: [ferrethealth] RE: a possible genetic route to reducing the risk of estrogen toxicosisfor whole females?
To: ferrethealth@smartgroups.com

This topic is under discussion on the FML (where it began) and on Ferret-Genetics, too.

As is to be expected with something that has a 50/50 chance of presentation the experiences vary, from those (anywhere) who have not encountered it to those (anywhere) who have.

I really had my curiosity peaked by Chris's UK observation in the FML that in one club it was less likely to happen in the fist heat than when older than that. Guess what I found afterward? In _Ferrets, Rabbits and Rodents_ (U.S.) I found that when an ovarian remnant causes estrogen toxicosis that also tends to not occur until a ferret is past the age of one year. It's in the first paragraph of that section in the 2nd edition on page 47. Isn't it great to see validation of an observation? I wonder why the older ones are more vulnerable?

Also, and this will feel like shades of adrenal discussions, there is a mention in one of the vet texts about reduction by providing enough darkness so husbandry practices appear to play a part. Again, page 47 of that text: 8 hours of light, 16 hours of darkness. (Also page 218 of _Biology and Diseases of the Ferret_)

It seems like this may be a situation in which breeding choices might be used to genetically reduce the rate of a health problem.

Interesting topic and perhaps an interesting opportunity.
