Genome-Wide Association Study of Egg-Laying Traits and Egg Quality in LingKun Chickens
Frontiers in Veterinary Science, 2022 Egg production is the most important trait of laying hens. To identify molecular markers and candidate genes associated with egg production and quality, such as body weight at first oviposition (BWF), the number of eggs produced in 500 days (EN500), egg ...

Non-destructive assessment of hens' eggs quality using image analysis and machine learning
Smart Agricultural Technology, 2023 Eggs are an essential source of inexpensive protein. Due to their oval shape, eggs can be efficiently handled, transported, and packed. The geometric description of the egg shape has been used as another parameter to evaluate the quality.

THE RELATIONSHIPS BETWEEN SELECTED EGG QUALITY TRAITS AND EGG SIZE
Nigerian Journal of Animal Production, 2021 The relationships between selected egg quality traits and sizes of eggs were studied in a part of the South Western Nigeria with a view to egg marketers and to investigating the variation in egg quality egg size changes. 320 market eggs and 40 freshly-laid eggs collected from a poultry farm were used for the study in which egg weight, specific gravity,
