Extract

A simple but approximate method of pedigree evaluation is presented with particular reference to dairy cattle. It involves the expression of information available on any animal in the pedigree in terms of the equivalent number of ‘standard progeny records’. Formulae are given for the transfer of evidence from generation to generation within the pedigree. The application to one rather complex pedigree is illustrated and it is shown that the loss of information through the approximation is small.
