Abstract
Aim of the present study was the estimation of genetic parameters of r ecords of first three single test-days and of 305-day lactation for mi lk yield and protein yield. Genetic parameters were estimated on 56840 records of Black and White first calvers of the herdbock association East Friesland. The results obtained therefrom are tabulated and discu ssed.
