EFFECT OF EGGSHELL OSTEOPONTIN PROTEIN ON SKELETAL EMBRYONIC DEVELOPMENT AND HATCHING TRAITS OF DEVELOPED CHICKEN STRAINS [PDF]
Egyptian Poultry Science, 2017 The present study was designed to study the change of shell quality, shell strength, hatching output, calcium (ca) and phosphorus (ph) concentrations in tibia bone for embryos and hatched chicks, bone strength and some related physiological parameters as

Is the Eggshell Quality Influenced by the Egg Weight or the Breeder Age?
, 2019 For a long time, it has been said that eggshell quality decreases as eggs increase in size, but this increase is seen as the breeder age advances. Therefore, the present study aimed to evaluate the age and egg weight effect on Cobb 500 broiler breeders ...

Environmental Toxicology and Chemistry, EarlyView.Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Food Chemistry International, EarlyView.Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Yolk vitamin D content and eggshell quality traits as affected by hen genotype and housing system
, 2023 A novel approach to fortify egg with vitamin D consists in sunlight exposure of hens as they are capable of endogenous vitamin D synthesis. The present study aimed to investigate the yolk vitamin D content and the eggshell quality traits of 5 hen ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations
Journal of Applied Toxicology, EarlyView.ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Effect of Dietary Acetylsalicylic Acid on Eggshell Quality
Poultry Science, 1991 Abstract Acetylsalicylic acid (aspirin) is an inhibitor of prostaglandin synthesis. Many soft-shelled (SS) and shell-less (SL) eggs are laid prematurely. It is hypothesized that prostaglandins may be responsible for the premature expulsion of some SS or SL eggs.

Eggshell Qualities as Indicative of Eggshell Strength for Layer Selection
, 2018 The study aimed at investigating which of four traits is the most representative of eggshell strength (destructive eggshell thickness measurement, eggshell weight, egg specific gravity, ultrasonic measurement of eggshell thickness) and could be used for ...
