Summary: This study aimed to evaluate the yolk and albumen color as well as the nutritional value of yolk lipids in Estonian quail eggs by using diets supplemented with local oilseed cakes. The diet affected the color, cholesterol content, and fatty acid composition of the yolk. The study found that different oilseed cake supplements had varying effects on the characteristics of the yolk and albumen in the quail eggs.

Summary: This study traced the rationale for developing the Haugh unit index and proposed a new Egg Quality Index (EQI) that showed wider potential in accurately reflecting egg quality grades. The comparison between the traditional HU index and the new EQI index revealed the advantages of EQI in assessing egg quality.

Summary: The study aimed to evaluate the features of hatching eggs in different ages and laying periods of geese. The results showed that with the increase of age, the weight and structure of the eggs increased while the shape index decreased. The yolk share decreased, but the albumen and eggshell increased. Additionally, the eggshell whiteness and the number of pores also varied with age and laying period. The findings of this study are important for adjusting incubation conditions and assessing egg quality.

Summary: The study demonstrates that ultrasound can effectively reduce the amount of E. coli in egg products, with a significant linear correlation between ultrasound energy dose and E. coli decrease. Near-infrared spectroscopy and principal component analysis can detect structural changes in egg samples.

Summary: This research aimed to determine the concentration of various elements in the egg albumen and yolk of Green-Legged Partridge hens in a free-range system, finding that different mineral content in feed mixtures (Gr-1 and Gr-2) significantly influenced the levels of elements. Overall, elements were generally higher in the FM from Gr-2 compared to Gr-1.

Summary: This study investigated the effects of dietary pomegranate seed oil supplementation on the performance and egg quality of laying hens. The results showed that there were no significant differences in body weight, feed intake, cracked and thin-shelled eggs, and egg weight among different levels of pomegranate seed oil supplementation. However, the addition of 250 and 500 mg of pomegranate seed oil tended to improve egg production and egg mass. Additionally, the inclusion of pomegranate seed oil increased eggshell weight, yolk index, and the content of conjugated linoleic acid and polyunsaturated fatty acids in the egg yolk.

Summary: This study provides a comprehensive view of the use of refrigeration in egg storage over the past century. Scientific evidence demonstrates that refrigeration has positive effects on the internal quality of eggs during storage. Asia has the most studies on this topic, and the Haugh unit is widely used to assess egg freshness. Conclusions and recommendations are made for the future use of refrigeration.

Summary: This study investigated the effects of dietary sodium humate (SH) supplementation on egg variables and physiological merits of laying quails under heat stress conditions. The results showed that the addition of 0.4% SH improved the quality, production, mass, and brokenness of eggs compared to the control group. In addition, the dietary SH also had an impact on egg shape, shell thickness, shell strength, cholesterol content, feed conversion ratio, and various physiological indicators and immune functions of the birds.

Summary: The effects of adding mixed chicken and Japanese quail egg yolks (EYs) to the cryodiluent on the quality of ram semen before freezing and post-thawing were evaluated. The study found that the use of chicken egg yolks improved sperm vitality, plasma membrane integrity, and DNA integrity, while the use of quail egg yolks improved sperm abnormalities and kinetic motion parameters. The addition of mixed egg yolks had no additional benefits for semen parameters.

Summary: The study demonstrated that supplementing Japanese quail breeders' diet with tomato pomace can significantly enhance immune response, antioxidant response, and digestive enzymes, decrease cholesterol and LDL, and increase HDL. The inclusion of tomato pomace positively affected the deposition of lycopene into the egg yolk, benefiting human health.

Summary: Natural melanocortins have been used to develop drugs with neuroprotective properties. The study revealed that two synthetic MC derivatives, Semax and ACTH(6-9)PGP, attenuated behavioral alterations under acute restraint stress conditions in rats and modulated the expression of genes associated with various biological functions. These peptides may correct disrupted gene expression patterns during acute stress.

Summary: High ambient temperature has a significant negative effect on the internal egg yolk quality parameters of poultry birds. This study explored the impact of heat exposure on yolk weight, yolk color, and egg weight in Huaixiang chickens, and identified upregulation of lipid metabolism-related genes. Understanding these mechanisms is crucial for mitigating the negative impact of heat stress on poultry production.

Summary: This article discusses the use of restricted movement as a model for inducing stress in laboratory animals, which is widely used in stress-related disorder research. Despite the various methods available, few studies directly compare the differential impact of these protocols. Additionally, there is a lack of standardized language distinguishing between restraint and immobilization terms in the literature. This review provides evidence of physiological differences in the impact of distinct restraint and immobilization procedures in rats and mice, highlighting the need for standardized language and further systematic studies to determine the best methodology for specific research objectives.
