EFFECT OF SEVERAL STRUCTURES OF CONTEMPORARY GROUPS ON ESTIMATES OF (CO)VARIANCE AND GENETIC PARAMETERS FOR WEANING WEIGHT IN NELLORE CATTLE

EFFECT OF SEVERAL STRUCTURES OF CONTEMPORARY GROUPS ON ESTIMATES OF (CO)VARIANCE AND GENETIC PARAMETERS FOR WEANING WEIGHT IN NELLORE CATTLE

We used actual and adjusted weights to 120 d and 210 d of age of 72,731 male and female Nellore calves born in 40 PMGRN - Nellore Brazil herds from 1985 to 2005 aiming to compare the effect of different definitions of contemporary groups on estimates of (co)variance and genetic parameters. Four mod...
