INDIRECT OR NON-GENETIC GENETIC ASPECTS AFFECTING CALF SURVIVAL
The binomial distribution of calf survival (lived or died) usually implies statistical difficulties. In addition, the frequency of pre-weaning deaths of beef cattle, in statistical terms, is often close to or even characterized as a rare event. Thus, the identification of genetic aspects of importance in survival, but which present normal or even categorical data distribution, can optimize the achievement of results in the survival of calves, in terms of genetic improvement and, consequently, in productive or economic terms. In addition, these are characteristics that can be considered when determining the mathematical model to be used in the genetic analysis of the survival of beef calves.

Abstract:
The binomial distribution of calf survival (lived or died) usually implies statistical difficulties. In addition, the frequency of pre-weaning deaths of beef cattle, in statistical terms, is often close to or even characterized as a rare event. Thus, the identification of genetic aspects of importance in survival, but which present normal or even categorical data distribution, can optimize the achievement of results in the survival of calves, in terms of genetic improvement and, consequently, in productive or economic terms. In addition, these are characteristics that can be considered when determining the mathematical model to be used in the genetic analysis of the survival of beef calves.
