Determination of Phenotypic Correlations Between Internal and External Quality Traits of Guinea Fowl Eggs
In this study, it was aimed to determine the internal and external quality traits of the Guinea fowl eggs as well as the phenotypic correlation among the these traits. Totally 100 Guinea fowl eggs were collected in three sequential days were used for this study. The birds were housed at Poultry Research Unit of the Department of Animal Science, Faculty of Agriculture, University of Akdeniz. Val...
متن کاملEvaluation of different egg quality traits and interpretation of their mode of inheritance in White Leghorns.
AIM The experiment was carried out to evaluate different external and internal egg quality traits and to figure out their mode of inheritance from a set of hierarchically classified data. MATERIALS AND METHODS The data collected from 548 progenies (1 egg from each progeny) of 282 dams mated to 47 sires (1 sire mated to 6 dams) of a White Leghorn flock were used in the present study. Phenotypi...
متن کاملEffect of Organic Selenium and Zinc on the Performance and Egg Quality of Japanese Quails
The present study aimed at evaluating the effect of the dietary inclusion of organic trace minerals selenium and zinc on the performance and internal and external egg quality of Japanese quails submitted to heat stress. Data on egg production, feed conversion (kg feed intake/ kg eggs and dozen eggs), egg weight, egg specific gravity, eggshell thickness and weight, Haugh unit, yolk index, albume...
متن کاملGenetic Analyses of Egg Quality in Khorasan Razavi Native Fowl Using the Bayesian Method
This study was conducted to estimate the genetic parameters influencing egg quality in Khorasan Razavi native fowl. (Co)Variance components were estimated by the Bayesian statistical method via Gibbs sampling in GIBBS3F90 software. 1000 eggs (28-29 weeks old) were collected from 775 hens of the ninth generation of Khorasan-Razavi Province native fowl breeding center. External (egg weight,specif...
