Home for Irish Setter Lovers Around the World
Ok Su.......sorry Mel call it CRAFT or SENIER moment.....well at my age what do you expect...hey Mel do the lines come with any other ''punishment'' ha ha....
On another subject:- I have read a lot about people who can't understand why some animals carry both Gene for rcd4, but don't show any signs of going blind...well I have looked into this, if anyone is interested...
1) Late Onset - time of testing ie they will develope rcd4
2) Incomplete penetration of the gene
3) Epistatic interaction with other genes
I think that all this means that the gene is 'interfered' with by another gene so this is why they don't actually get rcd4 blindness...
But this still means that they carry two coppies of the Mutant Gene so they will still pass this on...don't be fooled into thinking that becaus they don't go blind that they won't pass it on...
Hope this will help everyone understand this a little bit better...
I agree Colette that there has to be a 'structure' in place to breed decent quality dogs and I would not suggest mating dogs and bitches with no common ancestors at all.....just not ones who are too closely related.
I realise that many breeders have put years of hard work into their breeding programmes , but why do so many refuse to move with the times?
They have a wealth of knowledge at their fingertips and yet some still refuse to listen and learn how to help prevent health issues from occuring in the first place.
Colette wrote "If you take away line breeding then breeders will be no different to the ordinary person in the street having a litter to the nearest Irish setter who lives down the road."
I can't agree with this statement. Breeding for diversity can be done with just as much care and thorough research as line breeding . Indeed, done well, it may take more research of pedigrees and data about health and genetics, before the choice of a stud dog is made. And one can also preserve type, without line breeding, by choosing a stud dog with similar and desired phenotype but with a very different pedigree. It takes a good "eye" for a dog to be able to identify the one with the similar phenotype
I would even go so far as to say that successful breeding for diversity takes MORE skill and MORE thought and MORE knowledge than line breeding. Its an intellectual challenge to find and recognise that dog from different breeding who has all the attributes of both looks and health that one wants. It has nothing to do with how backyard breeders produce puppies
Knowledge about canine genetics has taken great leaps forward in the last twenty years, and anybody who keeps up with the research on canine genetics knows that pedigree dogs breeds have lost so much diversity in their gene pools through line breeding and inbreeding and the overuse of popular sires, and that it has become so much more difficult to avoid "bad" genes in a depleted and increasingly homozygous gene pool.
Susan is right, dog breeding has to move forward into a new era , where line breeding and inbreeding are not the only tools the breeder uses to achieve excellence, and there is more recognition that variation in type within a breed is actually healthy, and not everybody has to strive to clone the same look (which is usually the look of the current top winning dogs)
But Rome wasnt built in a day, and I guess it may take decades to change the dog breeding habits and beliefs of the last century :)) Fighting about it isnt very productive, people just get entrenched in their own dogma, the best one can hope for is to work together with other like minded breeders who have seen the light, and hope that when it becomes more evident that breeding for diversity produces dogs with fewer health problems, a new generation of puppy buyers and owners of brood bitches will vote with their cheque books
Hee hee Margaret................what a good idea!!!!! Funny you should say that because the stud dog of my last litter does indeed live only 45 minutes away, though not at all closely related. It certainly makes life easier when you are returning for several matings. Don't forget petrol costs...........wonderfully cheap!!!! Must do it more often....................
