hip qualityThis is from the American Forum...In English and very interesting.http://www.tg-tierzucht.de/hzucht/publikation/hq_bret.pdf |

That paper is well endowed with charts and figures which I for one certainly understand, but what it doesn't actually do is say how they measure Hip Quality - is it done by an eye examination of the dog, or by manual assessment, or are x-rays used?
What are these - how do they measure them? Annie |

These measurements are read with a German machine, I believe.
If you have access to the Yahoo group, it is all explained on there... No human error or differences of vet opinions. |

Did the report come from Cissi? if so I'll get her to explain it when I speak to her tonight. | ||||

Cecilie reported on the American Forum - "It was a German veterinary Dr. Beuing who made a machine and method who can read x-ray`s........
So in this calculation, its taken also relatives HQ in. So this will better show where the heritage is, not the factor we have with environment." She will ask someone on the NBK to give us a better explanation, but I think it is a machine that reads the x-rays rather than the human panel that we have here so it eliminates human error. In addition all the dog's relatives are also added into teh equation to come up wiht a HQ score for that dog. I have always said that we should be looking at the hip scores (that being the only method we have at present) of not only the breeding pair, but also their siblings and parents too, to try to get an overall picture. It appears that this German Vet is doing that but with the aid of a computer and mathematical formulae to more accurately assess the hips. Annie |

I know you asked Goldie but I will anyway answer on some of it 
"I am told environment and feeding/ exercise play a part too. " There have been a large research in Sweden on HD , it told that up against 70% is the environment. In here its bad feeding,to fat puppies up to one year. Food they grow to fast from . To much exercise and the wrong exercise, forexample at labrador, they found that if they played a lot of you know throw a stick to theme and catch. Then up against 50% more developed HD. Here they have had tests groups. To hard exercise before 1 year old. To much vitamin D + calcium also increase at lot. There is puppie buyers who will nothing more than good for their puppies, so they buy a lot of minerals , seal oil ( a lot of vit D ) and so on and give theme on top of the full forage they buy who contains already what they shall have. |

More or less what I always say to my puppy buyers - don't exercise your pup too much up till 8/9 months. I actually keep them in the garden till then with only lead or flexi walking outwith that.
Feeding and execise are things that breeders can't control once teh pups have been sold, so it is obvious that the only thing a breeder can do is use the scores. I would like to see results from this HQ method compared side by side to the HD scores. Annie |

On this one we differ...Not much exercise, but off lead...because when they find freedom and the big wide world..they 're off hunting the whole of the county 
10 mns free walking investigating smells and their surroundings is good in my opinion. At 8 and 9 months, I start more serious training. Does not mean to take them for miles, but walk incorporating discipline , sits, heel, recall. |

The genotype is the genetic makeup of the individual - usually talked about with particular reference to something specific - eye colour, coat colour, tail length etc The pheontype is the actual physical appearance of the animal Say a trait has two genes one dominant (D )and one recessive (d) the genotypes (not forgetting you get one gene from each parent) would be DD, Dd dD and dd . As D is dominant the phenotype of DD, Dd and dD would be exactly the same. Thus if there is a correlation between certain physical hip measurements and late onset of displasia; then measuring those parts of the hip will allow you to predict future health and by inference genetic makeup. |

So, Guy, how do you make a prediction...would you need the x-rays of the dam and sire and grandparents to analyse the growth patterns displayed...it is a tricky one, yes, when you consider that it is not all genetics that can cause this condition. |
