A COMPARISON STUDY OF PRODUCTIVE AND GENETIC PERFORMANCE BETWEEN SHARKASI NATIVE STRAIN AND IMPORTED NAKED NECK GENOTYPE CHICKEN

Abstract

This experiment was carried out at poultry breeders farm, Agriculture Research and Experiment Center, Shalaqan, Poultry Production Department, Faculty of Agriculture, Ain Shams University. This study was designed to comparing between native Sharkasi and imported naked neck genotype by study the productive and genetic performance. The naked neck and Sharkasi birds used in this study were heterozygous. Some measurements taken to compare between them: Incubation measurements (crossbreeding, hatchability and embryonic mortality) – Meat production traits (body weight, body weight gain, carcass characteristics) – Egg production traits (sexual maturity measurements, egg production traits & egg quality measurements) – Morphological measurements – Histological parameters and Genetic characters (AFLP Technique).

The main results could summarize as follows: 1. Incubation measurements: 1.1. Crossbreeding: • Two lines follow the Mendelian law and the native Sharkasi is an incompletely dominant gene like the imported naked neck gene and not a mutant in the native normal feathered breed in
