STUDIES ON SOME PRODUCTIVE TRAITS IN NORFA CHICKENS
Poultry Production Dept., Faculty of Agriculture, Menoufia University
Abstract
ABSTRACT: The current experiment had been carried out at the Poultry Farm of the Faculty of Agriculture, Minoufiya University, Shebin El-Kom, Egypt in the period of 2012 to 2014 for two generations to investigate the productive performance of Norfa strain as an indigenous Egyptian laying strain. A total of 528 birds (396 females + 132 males) of Norfa chickens were used. Artificial insemination was used as a mating system with sexual ratio 1 male / 3 females, and relatives mating was avoided. At hatching, all chicks were wing banded and pedigreed. Chicks were fed a starter diet containing 18.05% crude protein (CP) till 8th week of age and from 9th to 16th week of age, chickens were fed a growing diet containing 14.01% CP then, pullets were fed at production period a layer ration containing 17.46% CP. Cockerels were separated from pullets in brooding house at the 8th week of age and pullets were moved to individual cages in laying house at 16th week of age. A "step down-step up" lighting program was used durino-g brooding, rearing and production periods.
