Contenido: 	ABSTRACT: Genetic parameters for weaning weight (WW) and cow weight (CW) at different ages, CW1 to 
CW5 (24-42, 43-54, 55-66, 67-78, 79 to 120 months respectively) were estimated through a multiple trait model 
for the Hereford breed in Uruguay. Data consisted of 17875 WW, 7235 CW1, 6483 CW2, 4805 CW3, 3133 CW4 and 
4038 CW5. Posterior mean marginal estimates were obtained using Bayesian inference with the GIBBSF90 program. WW heritability was 0.13±0.03 using a dataset of 17875. Estimated heritabilities for CW1 through CW5 were 0.39±0.07, 0.48±0.04, 0.68±0.05, 0.59±0.06 and 0.47±0.08. Genetic correlation between CW1 and CW2, CW2 and CW3, CW3 and CW4, CW4 and CW5 were 0.93±0.06,
0.69±0.09, 0.90±0.04, and 0.90±0.05 respectively. Correlations are high but not consistent through all ages, so using
several CW might improve estimation of mature weight.
