Breed value - The SV Zuchtwert program for hips by mimi on 21 May 2012 - 19:17 |
| Hi all, What's your experience with the Zuchtwert (ZW) program (Breed Value Assessment) by the SV ? Is breeding two dogs with a low value (70-80) effectively better in producing normal hips than breeding dogs with a greater value? Any input, BREEDERS, would be appreciated! http://www.schaeferhund.de/site/index.php?id=688 |

| Of course...as you get closer or past 100 is when you may see dysplasia..70's is the best score |

The lower the number - the better -- but my understanding is that puppies start out with the AVERAGE of their two parents -- but as those puppies grow up and are bred - then the quality of their puppies (hip value A1, a2 - ETC) - affects their number -- it is not a static number -- If a dog with an 80 produces high numbers of excellent hips - his number goes down -- if he produces not-so-good to bad hips - his number goes up -- so It's a good sysem, i think with that kind of follow-thru -- The mother of one of my imported dogs had a ZW of 67 -- extremely low -- and she produced many litters of excellent hips with different males. The ZW of my new puppy is 80 and I'm perfectly happy with that too. When he's old enough, he will be x-rayed under the OFA evaluation -- we can only hope for Good to Excellent - but you never know -- Breeding the best hips you have to the best hips you can find (with generational back-up) has proven to improve overall quality - but not guarantee perfection . There are still OFA EXCELLENT dogs/bitches who can produce dysplastic pups - and there are FAIR dogs who cn produce EXCELLENT -- The person that breaks the dysplasia code will be very very rich--- until then we can only work with known genetics, nutrition and environment -- and always strive to do better. PS. - and not overlook elbows in favor of hips only - BOTH are extremely important as GSD carries more than half it's weight on the front end !! |

| Thanks for the info. I know how the program works however :) I am asking this question because a friend of mine had a female puppy with VERY severe HD. She had to be euthanized at 7 months old. Turns out her litter brother also had Severe HD and had to be euthanized too. (femoral heads were completely out of the non-existing sockets) Obvious proof to me that HD is a genetic disease....or her litter brother would not be severe too. Puppies were bought from a serious and nice breeder. Dam however had a ZW of 102 and sire had a ZW of 80. Please, share your experience. Pineridge, thanks for this info:
