Early change is manifested by slight bilabiation which shows as cranial curvature of a small outer segment of the CrAE. A good hip score for a Labrador is probably anything under 6 made up of even numbers on each side.
In Labradors the current five year mean is 12.
What is the average hip score for a labrador. The maximum score for each hip is 53. The maximum score for the dog is 106 ie. The breed average of hip scores for Labradors in Australia is about 9-12.
So it is recommended to only use breeding stock that have hip scores below the breed average. At the time of writing the BMS for Labradors is 12 This is the total for the two hips added together. You can check the latest data on the British Veterinary Association website.
A balanced score of 12 would be 66 a better score would be 33 and a perfect score would be 00. Outside of the UK scoring systems are different. The Labrador Hip Score in Australia if it is to be used for breeding should be below the breed average which is currently 93 The reason for this is so that the intent of breeding is to improve the breed and by continuing to only use breeding stock with Hip Scores below the breed average the overall quality of the breed is improving.
Since hip scoring in its present form started in 1984 a record has been kept of all Labradors hip scores and a running average More correctly called The Mean has been kept. This is known as the Breed Mean Score or the BMS for short. At present this is 15.
The guidelines on hip score for parents of Labrador puppies seems to be a total of 6 with equal numbers. I have two questions. 1 if either parent has a score of 45 total 9 I should delete these form my theoretical wish list.
Or in practice is this as good as it. 58 Zeilen The x-ray picture is sent by us to the BVA where a panel of experts examine the picture. This score ranges from 0 to 106 0 to 53 for each hip with a score of 0 representing the least degree of hip dysplasia and 53 representing the most.
Are my dogs results published. Costs of the scheme. Scores are from 0 - 53 with 53 being the worst per hip so the worst possible combined score is 106.
Breed average is about 16 IIRC so any combined score higher than this would indicate worse than average hips. Nine features of each hip are scored according to the degree of dysplasia observed 0 no signs and scores from each feature are summed to give a total from 053 for each hip and 0106 in total. Although voluntary the rate of participation in the UK is good.
For example 810 of all annually registered Labrador Retrievers the most popular breed in the UK with between 33 398. The best result is 00 which means there are no changes at all to the joints and the worst possible score is 5353 which means the dogs hips are very badly made and degenerative joint disease in the form of arthritis will set in very early in the life of the dog and will eventually probably overwhelm the individual. A hip score tells you what the hips looks like at that point in time - no more.
The Lab breed average is 12. 88 as a judgement of the hips appearance is preferable to 15 or 24 or 61 etc. If the sire with 88 is the best overall match for the 00 bitch.
Then there is nothing wrong with the breeding. From statistics gained in 2005 for various dog breeds it was found that the average Labrador hip score was 12 which compared favourably with breeds such as the Newfoundland which recorded a score of 21 and the Bull Mastiff which registered at 23. SCORE OF 2 - the CrAE is flattened throughout most or all of its length and there is usually both medial and lateral joint space divergence.
SCORE OF 3 - higher scores are given when there is positive evidence of abnormal wear andor remodelling of the edge. Early change is manifested by slight bilabiation which shows as cranial curvature of a small outer segment of the CrAE. In Labradors the current five year mean is 12.
Most Labrador breeders should be aiming to breed from stock with a hip score that is lower than average and balanced. This should result in gradual improvement in the breed over time. A good hip score for a Labrador is probably anything under 6 made up of even numbers on each side.
They will score this x-ray with each hip of the two hips scoring between 0 lowest and 53 highest. So if both hips are scored the total that dog achieves will be between a TOTAL of 0 and 106 2 x 53. Currently the breed average for a total of both hips sits at around 16.
The average and median numbers have been rounded to two decimal places. The average also called the mean is defined as the sum of the values divided by the number of values. The median is defined as the value separating the higher half from the lower half of a data sample a population or a probability distribution.
For a data set it may be thought of as the middle value. For example in the data set 1. The minimum score for each hip is 0 and the maximum is 53 giving a range for the total score of 0 to 106.
This total score should be compared to the breed median. If the dog is registered with the UK Kennel Club their results will be sent to the Kennel Club for publication on the Kennel Club website. Unlike the Hip scheme the highest score achievable under the KCBVA Elbow scheme is a total of 3.
The lowest mirroring the hip scheme is 0. Each elbow is scored individually and so its score will be like in hips a total of 2 numbers so for example 00. Genetic evaluation of hip score in UK Labrador Retrievers.

Currently the breed average for a total of both hips sits at around 125 for Labradors. So dogs around or under this score have average or better than average hips to give a guide. The score can also be shown sometimes as two numbers left hipright hip - so something like 54 total of 9 - good or maybe 3321 total of 54 - poor.
