%X the objective was to estimate environmental effects and genetic parameters on growth traits in a flock of farmed red deer of the central mexican highland. animals were raised on an intensive rotational grazing system of grass-legume mixed temperate pastures. evaluated traits were birth (bw), weaning adjusted to 100 d (ww) and yearling (yw) weights. analyses were performed using the mtdfreml program. final univariate animal models considered the fixed effect of sex-year, and calving age as a covariate for bw and ww, and the random direct (bw, ww and yw) and maternal (ww) genetic effects. means and standard deviations for bw, ww and yw were 8.7¡À1.2, 42.4¡À5.6 and 80.8¡À13.3 kg. males were higher (p<0.05) than those of females (4.6, 9.9 and 21.9 %, for bw, ww and yw). there were differences between contemporary groups for all traits (p<0.05). the linear effect of hind calving age was important (p<0.05) for both bw and ww. estimates of direct heritability were 0.00¡À0.08, 0.41 ¡À0.33 and 0.17¡À0.15 for bw, ww and yw. maternal heritability of ww was 0.22¡À0.16. based on the estimated genetic additive variability of ww and yw in this herd, the results suggest the possibility for genetic improvement of those traits through selection; however, these results are not definitive given the limited quantity and quality of the used information.
