The objective of this may was to evaluate the effect of genotype x environnent interaction and estimative genetic parameters of 205-day adjusted weaning weight observed in four different regions of Brazil. Data consisted of 56039 weight records of Nellore calves raised on pasture and born from 1977 to 1994. Genetic pammeters and expected progeny differences (EPD) were obtained using a sire model simultaneously for the four regions, having sire as randon effects sires and maternal permanent environment of cows and fixed effects sex month and year of birth, farm, and age of dam as covariate. The EPD estimates were obtained. Spearman correlations between EPD'S of different regions were calculated to verify whether the sire ranks were different among regions. The proportion of total phenotypic variance due to permanent environment effect of dam ranged from 0.16 to 0.23. Heritability coefficients were 0.27, 0.33, 0.39 and 0.25 for regions 2, 5, 6, and 8, respectively. Genetic correlations were 0.37, -.06,0.12, 0.36, 0.63 and 0.60. Spearman correlations were 0.60, 0.02, 0.40, 0.55, 0.87, and 0.78 for region pairs 2-5, 2-6, 2-8, 5-6, and 6-8, respectivility. |
