CHANGES IN RANGE OF PERFORMANCE TEST RESULTS OF GILTS OF POLISH LARGE WHITE BREED PRODUCED IN POLAND IN BYDGOSZCZ BREEDING REGION

The aim of the paper was analysis of changes in range of performance test results of 19782 gilts of Polish Large White conducted in years 1995-2004, produced in Poland in the area activity of Bydgoszcz Breeding Region, covering Kujawy-Pomorze Province. Animals were evaluated regarding to the same ob...
