Extract

There have been many studies of genetic variance in somatic cell score (SCS). Reported estimates of heritability (h2) range from 0.02 to 0.16, the lowest h2 obtained in the 1st parity and increased in the later lactations (Mrode and Swanson 1996). The objective of the present study was to examine the effect of introducing Holstein-Friesian genes in the Hungarian native breed on the inheritance of sample test-days SCS.
