The eggshell defect as a factor affecting the egg quality after storage

Poultry Science, 2023
The aim of the study was to assess the influence of shell defects on the quality of eggs after storage. The study material consisted of 1,800 brown-shelled eggs from cage rearing system which were candled on the day of laying to determine the shell quality. Eggs with the 6 most common shell defects (external crack, severe stripe marks, points, wrinkled,

Interaction between housing system and genotype in relation to internal and external egg quality parameters

Czech Journal of Animal Science, 2011
The effect of three housing systems (conventional cages, enriched cages and litter) on egg quality parameters was evaluated in two experiments with four brown laying strains ISA Brown, Hisex Brown, Bovans Brown and Moravia BSL. During 40 weeks of lay the

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

THE INFLUENCE OF LIQUID CALCIUM SOURCE ON EGGSHELL QUALITY

Archives of Veterinary Medicine, 2019
It is estimated that the world’s population will enlarge by 25% by the middle of this century, resulting in the food production increase by at least 60%. Intensifying egg production is one of the most affordable solutions to provide animal protein. Among many other efforts to improve the quality of eggs, special attention is paid to attempts to provide
