Lowest HD Zuchtwert - Page 1

I'm just curious, maybe someone knows. What's the lowest HD Zuchtwert of a dog at the moment? What dog is it? How far can it go down?

Akira, the lowest I have seen is 60. I do not know which dog currently has the lowest HDZW. You could email the SV and they can certainly tell you. As far as how far it can go down, that would probably depend on the dog. Let's say a male dog started out with 60, and then had a TON of progeny who all (every puppy, every litter, was hip rated and scored "a" normal--not exactly feasible, but this is just an example) were rated at "a" normal, then the dog's ZW has the POTENTIAL to go down to 0, from what I understand. This is fairytale assumptions, however, because no dog produces PERFECT progeny every single time, nor does EVERY dog owner hip certify.

about the official SV genetic ZW 63; 1 "Bueno von Salamanca", born March 1989 ZW 64; 15 dogs ZW 65; 16 dogs ZW 66; 36 dogs

One occassionally sees a dog or bitch with a ZW that is in the high 60's. Obviously a very good producer from very good lines, if everyone is telling the truth and submitting ALL of the x-rays of the progeny and siblings. Since this practically never happens it is probably of little consequence, and the dog earned that low ZW first from its parents, so that is a reasonably good indicator. The progeny tell 1/2 of the true story, as the other 1/2 is dependent on the mate of choice. If you really want a better answer to your question you will need to go the S.V.'s ZW website and do some reseach by trial and error. Or perhaps examine the most current S.V. Genetics CD-ROM and see if you can import and parse the statistics through a Borland database programme. Of course a published ZW can go up and down a lot in a dog or bitch's lifetime depending on the success of their progeny's hip evaluations. So what is true at this moment might very well be different tomorrow morning. How far can it go down? That is a really good question, as mathematically one would think it could go as low as 50 if the dog is from perfect parents and makes perfect progeny. But, add all of the other ancestors into the equation and the number begins to rise. So I would say that if you see a dog or bitch in the high 60's, then that is probably as good as it is going to be for the moment. However, if that same dog eventually produces one (1) dysplastic puppy that is graded by the S.V. then that dog's ZW will increase dramatically and quickly. It will take a lot of excellent progeny to lower it, and it may never be as low as it was in the beginning. The ZW is of the most value when it no longer represents just the ancestors, but is proven by the progeny of the dog. Bob-O

My Fina vom der Haumuhle has a ZW of 64. She is six years old. Veronica

Sorry, mistyped: SG Fina von der Haumühle

Sorry I have to correct! Lowest ZW (On SV-Genetics 01/2006) is: 61. Let me fill in some numbers: 61: 1 dog 62: 3 dogs 63: 9 64: 28 65: 22 66: 61 67: 154 68: 182 69: 452 70: 670 etc. I will soon put a chart on my website with the overall picture, please give me some time. And don't forget, HIGH is also possible! 175: 2 170: 1 168: 2 167: 2 165: 2 163: 2 etc.

I have now put an overall view on the Zuchtwerte (ZW) on my website for everybody who is interested. www.bloggen.be/hd Look for 'Zuchtwerte-Verteilung'. You're welcome to have a look. Jantie

Jantie, Can you name some of these very low dogs? Jonah

Hi Jonah! I do not know where you’re heading for, but just wanted to do you the favour of mentioning a few, maybe just to see how it looks like, just for fun. (Between brackets: their offspring) ZW61 HD1 Befferley vd Voortse Heide 1985 (7 HD1 + 1 HD6 out of 12 dogs) Sire was: Lord vom Tiekerhook! ZW62 HD1 Bixi v Rensefeld 1983 (8 HD1 out of 20 dogs) Yucca vd Kisslegger Burg 1996 (3 HD1 out of 6) (Too few dogs to be able to judge.) Maxi vd Grundschnelligkeit 1997 (13 HD1 out of 20) Sire was: Dasty v Gries (684 offspring, according to SV-records 78 % a1 = HD1!) With 48% of his pups x-rayed! Now THIS was a good producer. ZW63 HD1 Bueno v Salamanca 1989 (5 HD1 out of 13) (Too few dogs to be able to judge.) Iska vd Prinzenbrücke 1985 (17 HD1 out of 48) Nadja v Lechtal 1988 (17 HD1 + 2 HD2 out of 54) Can you believe the mating partners she had?: Cello Römerau, Hardy Arminius, Don Lennefetal, Cim Ecknachtal, Kimon Dan Alhedy’s Hoeve, Jeck Noricum, Hanno Wienerau, Eros Luisenstrasse – talking about sleeping with the top!) Kessy vd Pfenningbacher Höhe 1992 (11 HD1 out of 17) (Sire was: Troll vom Körbelbach!) Orna v Hammerbachthal 1992 (7 HD1 out of 20) Belinda v Laucherttal 1993 (8 HD1 out of 10 – some sired by Wanko vd schwarzen Seeperlen) Daisy v alten Wingertshaus 1995 (24 HD1 + 2HD2 out of 58) 10 Litters?!? (Some pups sired by Quasy vd bösen Nachbarschaft! And Immo Rosseleck.) Senta v Bisschofsheim 1998 (4 HD1 out of 4) (Too few dogs to be able to judge.) Fina vd Haumühle 1998 (7 HD1 out of 20) Next step would take investigation of 28 dogs with ZW64, I hope I’m excused! Have fun!
