Review on Flock Improvement through Genetic Selection and Culling of Laying Flock of Poultry Production

Abstract

This study reviews the improvement of layers through genetic selection and culling from the laying flock, with the aim of delivering summarized information for the beneficiaries and reader. Poultry production is increasing globally due to increase population number and increased demand of poultry products. Poultry production plays a great role for the supply of egg and meat from rural and urban area as a source of small holder family income. Even though all chickens are not equal in reproductive and productive performance, there is detrimental factor for the increment in poultry egg production by genetic improvement of laying flock through selection of the best layers and culling of undesirable or unproductive chicken from the flock by considering different parameters for egg production such as ( age at sexual  maturity; weight at maturity; body weight)

Keywords: flock, layers, culling, selection, and production.
