Variance components and genetic trend for somatic cell count in Norwegian Cattle

2003-02-01

Abstract excerpt

First-lactation mean somatic cell score (LSCS) in Norwegian Cattle, sampled during 1978-1995 for 1.3 million cows from 2043 sires, were used in genetic analyses. Variance components and genetic trends were estimated for four linear sire models with alternative definitions of contemporary group effects. Model validation demonstrated necessity to separate environmental time trends from genetic trends by modelling co...
