STUDY OF THE GENETIC DIVERSITY AND PRODUCTIVE PERFORMANCE FOR SOME DUCK LOCAL STRAINS USING MOLECULAR GENETICS

Abstract

This study aimed to evaluate the Genetic Diversity and productive performance for two native Duck strains (Sudani, SUD and Domyati, DOM) using Microsatellite genotyping analysis. This investigation was done throughout three main parts. The 1st part, deals with the base breeding flock which consist of 600 ducks from both strains and aged 10 months. Some productive traits were determined: Body weight, Body measurements: Shank length, Keel length and body circumstance, fertility and hatchability and external and internal egg quality measurements. In the 2nd part, the present study performed using 50 day old duck chicks from each strain. The comparison was held between these strains for different productive traits: Body weight, Body measurements, Mortality rate, feed consumption, feed conversion, carcass measurements and weight of some lymphoid organs and some blood constituents were determined. The 3rd part Molecular genetics technique was carried out to study the Molecular genetic diversity for both strains by isolating the DNA from random twelve venous blood samples (6 samples of each strain) and protein analysis.
