This study examined the effect of rapid cooling with air and CO2 on shell egg quality over 14 wk. The 240 fresh eggs were initially heated to 47 C for 24 h in an incubator, cooled using rapid air cooling or CO2 cooling, and then stored in air or CO2 in 250-mL jars for 14 wk. The CO2 levels were recorded of the jar atmosphere, of the egg air cell, and of the egg albumen. The Haugh units of each ...
The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...
This study was carried out to investigate the effect of two housing systems on external and internal egg characteristics of a commercial laying bird. Two hundred and eighty pullet of Nera layers were divided into two even group kept in different housing systems (deep litter vs cage). External and internal egg quality traits were examined at 26, 30, 34 and 38wk. Data were then collected on egg w...
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...
Recently, some nondestructive methods for the assessment of albumen freshness were developed. Among others, visible near-infrared transmission spectroscopy and low-resolution proton nuclear magnetic resonance (LR (1)H NMR) measurements were proposed. This study was performed to evaluate the potential of the combined measurement of visible near-infrared transmission spectroscopy and LR (1)H NMR ...
Cold and immobilization stressors can generate oxidative stress as well as skeletal muscle fatigue. Free radicals cause oxidative degradation of lipids, proteins, nucleic acids, and carbohydrates molecules, thereby compromising cell integrity and function. Quail egg had been described as being very functional biochemically, due to the essential biomolecules it contains in very regulated quantit...
This study aimed to determine the effect of storage time second phase chicken herbal eggs at room temperature on egg weight loss, air cell diameter, and albumen index also best for eggs. research was conducted 7 October until 4 November 2020 Animal Production Laboratory, Department Husbandry, Faculty Agriculture, University Lampung. used a completely randomized design (CRD) with 5 treatments 0,...
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...
