Poultry egg quality
Egg quality defines those characteristics of an egg that affect consumer acceptability and preference. Components of quality include shell quality and interior egg quality for shell eggs, and interior egg quality for further processed eggs. The quality of the egg once it is laid cannot be improved. Hence, its maintenance is mostly a preventive process. Egg quality is influenced by several factors including rearing, temperature, humidity, handling, storage, and egg age. Shell quality: There are five major classes of shell defects: integrity, texture, shape, color, and cleanliness. Internal egg quality involves functional, aesthetic and microbiological properties of the egg yolk and albumen. The proportions of components for fresh egg are 32% yolk, 58% albumen and 10% shell. Regarding exterior egg quality, the shell of each egg should be smooth, clean and free of cracks. The eggs should be uniform in colour, size and shape.

Gut health challenge is one of the major factors affecting production and profitability in commercial laying hens. In addition, chronic heat stress results in lowered feed intake, egg production, egg quality, gut microbiome and also impairs acid-base balance in laying birds. Numerous data support that laying birds fed with organic acid improved egg production and quality (Sakdee et al., 2018; Zhang et al., 2022). Butyric acid, an important organic acid serves as a primary source of energy...

Increased global production, and consumption of the hen egg; and the popularization of nutritional knowledge, places greater emphasis on egg quality, safety, and freshness. An understanding of the interaction between several egg quality indicators is necessary. A total of 300 freshly-laid eggs were analyzed within 24 hours of collection to investigate the phenotypic correlations between internal and external quality indicators. Eggs were analyzed for egg weight, breaking strength,...

1. Introduction Trace minerals such as zinc (Zn), manganese (Mn), and copper (Cu) play critical roles in bone formation and eggshell quality [1,2]. Zn supports bone and cartilage integrity by facilitating collagen formation and hydroxyapatite crystallization [3], while Mn contributes to bone development by activating enzymes involved in synthesizing mucopolysaccharides in bone cartilage [4,5]. Cu is essential for maintaining bone tensile strength by aiding in the cross-linking of...

1. Introduction “Feed-food competition” was defined as “the tensions and trade-offs between two alternative uses for edible crops: direct consumption by humans versus feeding livestock” (1). However, feed-food competition includes the use of production resources, such as land, wild fish, and water, and labor, capital, and ecosystem services. The allocation of these resources between all their possible uses is often determined by which end use is most...

INTRODUCTION The ability to maintain an affordable, safe, and sustainable food supply is a global challenge. Meat consumption trends are changing, with increasing preferences for cheaper and processed white meat and a decline in cereals share of the total food (Sefeedpari et al., 2013; Faridi et al., 2011). The consequent increases in poultry meat production by a factor of seven (3206%) and eggs by a factor of three have overburdened sustainable production (Sousa et al., 2005)....

Some breeder flocks have higher egg peak production, 92%, whereas other breeder flocks reach 82% at egg peak. On the other hand, some broiler breeders lay a good peak egg production, but as hens age, egg production descends more than expected. In this situation, how can we increase the persistence of egg production in broiler breeders? Breeder managers should evaluate the following four points for improving the persistence of egg production: (a) body weight uniformity and peak egg...
