Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

Animal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Marl for Laying Hens

Poultry Science, 1935
Abstract KENTUCKY marls or calcareous clays are usually soft, calcareous-magnesian shales or soft, clay-containing magnesian limestone which breaks down on weathering into finely divided particles. In recent years marl has been used extensively because of its cheapness and easy accessibility, as a source of lime for soils.

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.

Multi-omics profiling of hepatic macromolecules in laying hens with difference feed intake: Mechanistic insights into antioxidant capacity modulation

Poultry Science
Currently, the cost of poultry feed accounts for more than 70 % of the total cost of poultry production. Therefore, it is crucial to find appropriate strategies to reduce feed cost and improve feed efficiency in livestock genetic improvement programs ...

Maatregelen ter vermindering van fijnstofemissie uit de pluimveehouderij: gescheiden bedekte strooiselruimten bij legkippen = Measures to reduce fine dust emission from poultry houses: separated covered floor bedding for laying hens [PDF]

, 2010
In this study it was investigated whether covered bedding areas are able to reduce dust emissions from laying hens. The study shows that laying hens in an aviary system preferred dust bath behaviour under the tiers.
