Recent progress in poultry reproduction

Abstract

The identification and maximization of the use of superior sires has been prompted by great improvements in the growth rate and meat yield of meat-type poultry. This paper highlights a few areas of recent research on spermatozoal production and function and on management procedures concerned with selecting and maximizing the use of elite sires. Methods of semen evaluation, improved methods of storing and spreading semen, factors affecting the inherent quality of spermatozoa, retention of membrane integrity of spermatozoa in vitro and their survival in the oviduct are reviewed.
