More Genomic Breeding Values on the Polish scale
What is PF and gPF?
The PF for “Production and Functionality” is the total merit index that is used in Poland for ranking bulls according to the Polish breeding goal. As soon as genomic information is available, gPF can be computed.
What are the benefits of using gPF?
gPF is a breeding goal that aims for Production and Functionality. In 2014, weights for particular traits was changed and the breeding value for longevity was added.
How to understand gPF?
- 95% of the bulls of the Holstein animals evaluated in Poland have breeding values between 80 and 120. This means that bulls with a proof over 120 represent the top 2.5% of the breed.
- Breeding values on the Polish scale have an average of 100 and a genetic standard deviation of 10.
Who is responsible for estimation and publication of breeding values?
The National Research Institute of Animal Production in Kraków-Balice is collaborating with the universities of Wroclaw and Olsztyn to compute genomic breeding values, on a monthly basis. The National Research Institute of Animal Production in in Kraków-Balice is also responsible for the offical publication of national and international breeding values.
Where do you search for the gPF of a specific sire?
gPF and all other breeding values calculated by the National Research Institute of Animal Production in Kraków-Balice can be found on the official website.
