New report: The Impact of Generation Interval

MeatlincPedigree breeders often ask how they can make faster genetic progress within their flocks.

The rate of genetic change achieved within a flock is dependant on three things:
• The heritability of the trait
• The selection pressure
• The generation interval

Breeders have little influence on the heritability of the trait, but they can often increase the selection pressure within their breeding programmes.

Whilst these two secrets to success are obvious, many breeders could also decrease the generation interval within their flocks, making better use of the genetic improvement that they make each year.

The following paper outlines how breeders can exploit differences in generation interval.

Reducing the Generation Interval
