The degree of kinship of an animal is an expression for the genes that an animal has in common with the reference population of his own breed. A black Holstein Friesian bull is only compared with black Holstein Friesian cows. For a bull to get a degree of kinship certain criteria have to be met:
The degree of kinship is only calculated for the breeds which have their origin in the Netherlands and Flanders, such as HF (Holstein Friesian), MRY, FH (Dutch Friesian), Belgium Blue etc
The calculated degree of kinship is expressed in percentages, as a integer.
This means that for a bull with a kinship of 8, 8% of his genes are in common with the cows of his own breed.
In the Dutch and Flemisch Breeding Value estimation many of the Breeding Values are published on a relative scale.
This means that the unit of observation is different from the way breeding value of the trait is published.
A relative breeding value has an average of 100 and the standard deviation is 4 points. Most animals will have a breeding value between 88 and 112 points.
With an average breeding Value of 100, the frequency of animals with a certain breeding value in the population is:
| Breeding Value | Frequency |
|---|---|
| < 88 | 0.1% |
| 88-91 | 2.2% |
| 92-95 | 13.6% |
| 96-104 | 68.2% |
| 105-108 | 13.6% |
| 109-112 | 2.2% |
| >112 | 0.1% |
