the present study was conducted to estimate correlations among performance and egg quality traits in iranian native fowl. data were collected from 21,679 birdsat the isfahan native fowl breeding center to derive genetic parameters for performance traits and egg quality traits were measured on eggs of 1,020 birds. genetic correlations of performance and egg quality traits were estimated with a b...

This study aimed to determine the effect and best of storage time for first phase herbal chicken eggs at room temperature an average 29,3°C on decrease in egg weight, air cavity diameter, albumen index. research was conducted 7 October--4 November 2020 Animal Production Laboratory, Department Husbandry, Faculty Agriculture, University Lampung. used a completely randomized design method (CRD) wi...

Hen egg plays a crucial role in the development of embryonic bird. It serves first as source of energy and nutriments of high digestibility and, second, protects embryonic bird against external aggressions. The unique structure of egg with yolk containing the embryo surrounded by albumen and shell as physical barriers is the first element of this protection. The second one consists in the pecul...

Applicability of the TOBEC method (electrical conductivity) was tested for the in vivo determination of different egg components and for the separation of eggs with different composition. Altogether 300 hen’s eggs – originated from a 36 weeks old ROSS-308 hybrid parent stock – were measured by TOBEC, and the extreme and average 5-5% – based on the measured values – were chosen for chemical anal...

We used a split-plot design of five diets: control (corn-soy) with 3.8% Ca, 10% flaxseed with 3.8% Ca, 10% flaxseed with 4.5% Ca, 10% flaxseed with 3.8% Ca and 22,000 IU vitamin D3/kg, and 10% flaxseed with 4.5% Ca and 22,000 IU vitamin D3/kg, and two strains of birds, DeKalb Delta (DD) and Hy-Line W-36 (HL), to evaluate long-term effects of flaxseed supplementation on egg production parameters...
