We present. an appl ication of the proportional hazard-proportional hazard cure models to evalu ate the environmental and genetic factors that affect both mortality and survival up to weaning of beef calves. We usc the ntlm I>ackage (software R.) to fit. nonlinear sem iparamctric transformation models, which include the proportional hazard cure models as a specia l case. Results indicate that genetic factors such as calv in g month and calvin g diHlculLy are associated with the long-term sur vivors hip of the calves.
