s of papers 89 feed, warmth and potential negative social interaction are potential factors that could affect mortality immediately after hatch. The post-hatch body weight at time of mortality used as a risk factor indicated that the divergently selected lines have about the same risk and less sensitive to reduced body weight compared to the control population. Through survival analysis, this study has demonstrated that factors that causes reduction in post-hatch body weight are risk factors for mortality in growing birds.
