Background: To evaluate the role of 3D, 4D and color Doppler ultrasound (US) in the assessment of early human development. Materials and Methods: 380 women with uncomplicated early pregnancy between 5 and 14 weeks were evaluated by 3D, 4D and color Doppler US. Results: Regression analysis revealed exponential rise of the gestational sac volume with gestational age throughout the first trimester...

this experiment was conducted to investigate the effects of various levels of cichorium intybus andcopper on performance and egg yolk cholesterol. total of 324 layer hens (hy-line w-36) were used in arandomized complete blocks with nine treatments, three replications of 12 birds in each from 38 to 50weeks of age. experimental diets include control, four levels of copper (150, 200, 250 and 300 m...

Current commercial broiler products are derived from the crosses of various strains at the primary breeder level. This study investigated chick development, yolk utilization, and early growth rate of males from 8 broiler breeder strains. These strains were a combination of both specialized and commercial-line products. At hatch, 110 male chicks per strain were weighed and wing-banded, and chick...

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...

Three experiments were conducted to investigate the effect of increased egg temperature during the final third of incubation on BW, yolk sac, heart, and digestive organs of broiler chicks at hatching. Egg temperatures were found to be approximately 1.0 to 1.5 degrees C higher than incubator air temperature. Elevated egg temperature (39.5 degrees C) after embryonic day 14 generally accelerated h...
