Abstract
New methods will be developed to analyse survival data in livestock species, using all available phenotypic and genetic information. Observed survival will be modelled as a series of binary traits. For the genetic level, survival is modelled as a series of liabilities on an underlying, unobserved, scale. The non-linear relationship between survival and production traits will be modelled. Survival will be partitioned according to competing risks, including voluntary and involuntary culling. Data from the dairy industry on the production and survival of progeny of bulls throughout multiple lactations will be used to estimate genetic parameters, predict response according to different selection strategies and predict the breeding values of bulls for survival of their daughters. This work allows the possibility to unify the prediction of breeding values for animals with the estimation of genetic parameters.
