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.

I. INTRODUCTION Severe feather pecking (SFP) is an abnormal behaviour which reduces both hen welfare and the efficiency of egg production. While the specific causes are unknown, it is acknowledged to be multifactorial, complex and unpredictable (Rodenburg et al., 2013; Hartcher et al., 2016). The problem is compounded because the behaviour seems to spread rapidly via social learning (Zeltner et al., 2000) and is therefore difficult to control in large groups of hens. A reliable...

Flock uniformity is crucial to increase the performance and profitability of commercial egg production (Corzo et.al, 2004). Obtaining flock uniformity in a free-range system may be challenging due to the variation in feeding and ranging behaviour of individual birds. The current study investigated the effect of body weight on initial range utilization and flock uniformity in two free-range laying flocks. A total of 6,250 Lohmann Brown hens were weighed and assigned to 2 identical...

1. Introduction Respiratory diseases control is crucial in all types of poultry including laying hens. Respiratory infections in layers can considerably impair bird health and welfare, as well as performance and hence profitability of flocks [1]. Although in broilers respiratory diseases mostly affect the respiratory tract itself, in layers respiratory infections affect both the airways and the oviduct [2]. Therefore, respiratory disease can have a significant economic...

1. Introduction Gut microbiota, represented by bacteria, archaea, viruses, and eukaryotes, take part in regulating several functions in both humans and animals [1]. It has been estimated that the chicken gut can be colonized by at least 1000 different microbial strains that are involved in maintaining the intestinal health of hens while sustaining productivity and growth [2,3]. This microbiota takes part in various metabolic pathways related to nutrient digestion and absorption,...

1. Introduction The increase in food demand driven by population growth, coupled with the reduction in the supply of raw materials owing to factors such as climate change, poses a significant challenge for the agricultural and livestock sectors. Among the different processes associated with egg production, the feeding of hens represents the largest source of environmental impact [1]. Nonetheless, the revaluation of agrifood by-products through their incorporation into animal diets...

The 2022–2023 highly pathogenic avian influenza (HPAI) H5N1 outbreak in the United States (U.S.) is the most geographically extensive and costly animal health event in U.S. history. In 2022 alone, over 57 million commercial and backyard poultry in 47 U.S. states were affected. Over 75% of the affected poultry were part of the commercial table egg production sector. Methods: We conducted a case–control study to identify potential risk factors for the introduction of the HPAI virus...

INTRODUCTION The initial stage of a laying hen's life is crucial for its development. During this period, optimal nutrition is essential for ensuring strong performance and high egg quality throughout the hen's productive lifespan (Rentsch et al., 2023). During this phase, young laying hens undergo significant physiological changes, including the development of reproductive organs and the initiation of egg production. Adequate nutrition during this period is crucial for...

I. INTRODUCTION The inclusion of alternative ingredients such as rice bran, DDGs and sunflower meal in layer diets, to reduce feed cost, can result in higher phytate levels, potentially limiting availability of minerals, protein and energy, all of which are important to maintain egg production, eggshell strength and bone strength (Bello and Korver, 2019). Phytase enzymes are commonly used in the animal feed industry primarily to increase phosphorus (P) availability from plant...
