Genetic parameters of milk traits of red-white cattle
Języki publikacji
Abstrakty
13476 pairs of mothers and daughters from 165 herds of red-white cattle used In 1963-1983, in Low Silesia and Opole region were studied. The values of all the traits analysed /milk and fat yield, fat content in milk/ were expressed as deviations of the means for the herd-year. Corrections were made for age and the season of calving. The evaluations were based upon the data referred to above; heritability, phenotyplc, genetic and environmental correlations were calculated in pairs of mothers and daughters. The values of heritability, phenotyplc correlations, particularly environmental correlations, were higher than those in the same breed estimated by similarities in half-sib groups. Incomplete elimination of parts of some common environmental influences for daughter and mothers could have caused that effect, in particular, the Influence of maternal environment.
