Evaluation of maternal effects and detecting major genes affecting internal egg quality traits of Azerbaijan native chickens

Detecting major genes affecting internal egg quality traits.
Evaluation of maternal effects and detecting major genes affecting internal egg quality traits of Azerbaijan native fowls.
After data collection of internal egg quality traits from Azerbaijan native fowls, the probabilities of major genes segregation were separately studied in all traits with a univariate animal model using Bayesian analysis and major gene index (MGI) procedure.
The major gene index calculated using outputs from univariate animal model and segregation of major genes was confirmed for internal egg quality traits including yolk weight, yolk width, albumen pH, yolk pH, yolk to albumen weight ratio, yolk index, yolk and albumen percentages and finally for yolk and albumen dry matter values in Azerbaijan native fowls.
Given that major gene segregation was confirmed using MGI and for internal egg quality traits, it is concluded that probability of major gene segregation is confirmed for traits such as yolk weight, yolk width, albumen pH, albumen weight, yolk index and spot when is considered all population. Therefore, by using an accurate major gene detecting design slike half -sib family design in West Azerbaijan’s native fowl breeding center and using molecular markers, it is possible to accurately detect the major genes for these traits and also determine the effect sof these genesand their location on fowl chromosome, accurately.
