Abstract

The objective of this work was estimate the genetic correlations, environmental and phenotypic on the birth weight (WB) and on the 205 (W205), 365 (W365) and 550 (W550) days of age, in animals of the polled nellore breed from Bahia state. The analyses were carried out by software MTDFREML. The genetic correlations were 0.08 (WB and W205), 0.00 (WB and W365), - 0.14 (WB and W550), 0.90 (W205 and W365), 0.81 (W205 and W550) and 0.97 (W205 and W550). The environmental correlations were 0.12 (WB and W205), 0.11 (WB and W365) and 0.16 (WB and W550), 0.35 (W205 and W365), 0.13 (W205 and W550) and 0.54 (W365 and W550). The phenotypic correlations were 0.09 (WB and W205), 0.05 (WB and W365), 0.00 (WB and W550), 0.75 (W205 and W365), 0.65 (W205 and W550) and 0.87 (W365 and W550). The birth weight presented weak genetic, environmental, and phenotypic associations with the others weighting. On the other hand, the values gotten for the genetic correlations between the other weighting, indicates that the selection for weight in young ages will promote changes on the future weights of the animal.
