ABSTRACT

  The problem of model selection in animal breeding is examined
using Akaike's Information Criterion. A detailed procedure is
presented for the mixed linear model. A simulation study was
designed based on field data on Japanese Holstein cows. Criteria
related to Akaike's information criterion, extensions of the 
proposed procedure, and computational difficulties are discussed.
