Genetic and environmental parameters estimation for milk traits in Slovenian dairy sheep using random regression model
dairy ewes test-day records orthogonal Legendre polynomials heritability additive genetic correlations
2015/6/24
(Co)variance components for daily milk yield, fat, and protein content in Slovenian dairy sheep were estimated with random regression model. Test-day records were collected by the ICAR A4 method. Anal...
Genetic parameters for somatic cell score in the first three lactations of Czech Holstein and Fleckvieh breeds using a random regression model
test-day somatic cell score random regression model genetic parameters Holstein cattle Czech Fleckvieh
2015/6/9
A multiple-lactation random regression model was applied to test-day somatic cell score (SCS) records from the first three lactations of Czech Holstein and Fleckvieh cows. For Holstein, the data inclu...
Genetic evaluation of daily gains of dual-purpose bulls using a random regression model
daily gains curve random regression heritability correlation bulls
2015/6/5
Daily gains of 8 243 dual-purpose bulls from 100 to 400 days of age during the years 1971 to 2007 were analyzed by random regression models. Orthogonal Legendre polynomials (LP) of degree 4 were appli...
Bias in genetic evaluation using random regression test-day model
