Booroola (F) Gene: Major Gene Affecting Ovine Ovarian Function

Part of the Basic Life Sciences book series

Abstract

The Booroola Merino is one of a small number of sheep breeds with high genetic merit for prolificacy, defined here as the number of offspring per pregnancy. These breeds (Tab. 1) are valuable genetic resources for the genetic improvement of sheep reproductive efficiency, since they can be used to bring about by genetic substitution rapid increases (40–60%) in prolificacy of other sheep populations. Genetic progress of this magnitude would require about 30 years of within-breed selection for prolificacy to achieve the same result.
