Breeding systems and selection strategies for sheep improvement in Cyprus

Mavrogenis A.P.

The aim of any breeding programme is to genetically improve one or more traits of economic importance in a population. The choice of any breeding and selection system depends on the degree of inheritance of the trait(s), the selection pressure (selection differential) and the generation interval. The necessary prerequisites to ensure genetic progress are the implementation of a performance recording scheme and of sound evaluation procedures and the organization of a programme for the dissemination (diffusion) of improved genetic material in the population. Animal breeding in Cyprus aims at improving genetically milk and meat production through selection and/or crossbreeding, the production of improved types suitable for environmental conditions they are called to perform in and the evaluation of the important environmental effects affecting animal productivity. The performance of purebreds and crossbreds under a semi-intensive production system, the procedures followed for the evaluation of superior individuals and the selection systems are discussed. Future work on breed evaluation and selection procedures and the formation of a synthetic breed involving two sheep breeds are also presented.
