The aim of this study was to investigate the genetic and phenotypic correlations of egg quality traits in Khazak chicken. Albumen height (AH), albumen weight (AW), eggshell color (ESC), yolk color (YC), eggshell index, long length of egg (ELL), short length of egg (ESL), eggshell weight (ESW), egg weight (EW), Haugh units, and yolk weight (YW) were measured in 201 eggs collected 6 d sequentiall...

The aim of this study was to evaluate the effect rearing systems and genotypes on production performance egg quality. Isa Brown New Hampshire were used in study. These two housed floor organic systems. During experimental period, which lasted one year (52 weeks), following parameters recorded: production, daily mass, feed consumption, conversion efficiency, mortality. Fifteen eggs per group col...

The present experiment was planned to ascertain the effect of dietary incorporation chili (Capsicum annuum) leaf powder on production performance and egg quality parameters Rhode Island Red laying hens 28 weeks age for a period 12 weeks. Hens were individually weighed then randomly assigned into four treatment groups with three replicates 6 birds each viz., T1: (control, containing basal diet);...

to determine the effect of hen age and storage condition on egg quality, fresh eggs were sampled from two commercial flocks of white leghorn hens at 28 and 68 weeks of age. half of sampled eggs from each flock were stored at 6°c and the other half was stored at room temperature. fifteen eggs were randomly sampled from each treatment following collection and at 5-day intervals to 30 days of stor...

The present study was carried out during two successive generations beside base generation, to improve egg mass (EM) through selection in developed Baheij chicken strain and to study correlated response of some production traits. The results showed that: 1Egg mass means for based generation (G0), first generation (G1) and second generation (G2) were 1741.29, 1904.52 and 2157.38g for S line and ...

The effects of 6/85-strain Mycoplasma gallisepticum (6/85MG) inoculation alone or in conjunction with a F-strain M. gallisepticum (FMG) overlay and its timing on the performance of commercial egg-laying hens were investigated. Control birds received sham inoculations at 10 wk of age. A second treated group of birds was inoculated with 6/85MG at 10 wk of age, a third treatment group of birds was...

AIM The objectives were to study the morphology of the foramen magnum in dry skulls and to evaluate its antero-posterior diameter, transverse diameter and the foramen magnum index. MATERIAL AND METHODS The foramen magna of 53 dry human cadaver skulls that were obtained from the neuroanatomy laboratory were examined. Different shapes of the foramen magnum were macroscopically n...
