This message is from: [EMAIL PROTECTED] Hello Kathy, Could you go into more detail about this, please? Thanks much!

Remember, this number refers to the "effective" breeding population, those individuals that are actually producing offspring (not to the total population number); and the calculation of the "effective" number is reduced if some individuals (usually sires) are used to a disproportionate extent.

It also applies the other way in that you can come up with a population with a higher percentage of not so desirable traits. The remedy is to keep the gene pool large and avoid creating barriers, artificial or real which would isolate one population, unless a larger population is also available from which to go back and recover "lost" genes. This is why diversity is good, for example in the Fjords, and narrow specialization Okay as long as not all of the individuals go the same way. Kathy

Anything else you want to know, this is the weekend to ask. Would that be 10,000 total registered, or 10,000 alive right now? If the latter, what's the total they had registered? Thanks, Lori

T he clinic is doing well, learning lots about grooming, new to all was the burning of hair under the chin. Today we practice evaluation before the horses (20) are evaluated and all about planning breeding. Tomorrow performance evaluation. I already have 5hrs of video! Anton V.

I am not to sure about that 15,000 number for Holland either. That is a LOT of Fjords for the size of Holland. Is that possibly the number Registered? That would also include deceased horses then. We have 2,174 registered right now. Of that number 2,120 are still alive. Of the registered horses; 646 are Geldings 285 are Stallions (some of these are probably gelded but not reported to me) 1,243 are Mares 102 are Norwegian Registered also. 191 are Association Registered also. 111 are Dutch Registered also. 231 are Canadian Registered also. I also have a copy of the latest Canadian Stud Book. It shows that they have 1,628 horses registered. I don't have any numbers for the Association but I know they are over 1,000 anyway. I don't have any idea of how many the FBA has registered either but just for argument sake lets say 500. So if we add up the North American numbers now we have 5,302 horses. Some are dead, some are counted in more than one registry. So I would be willing to say that we have about 4,500 registered horses in North America. I am sure there are a lot of unregistered ones out there too. Especially geldings.
