Response of three laying hen genotypes to two feed calcium levels

Czech Journal of Animal Science, 2019
The present study aimed to evaluate the effect of two dietary Ca levels (3.00% vs 3.50%) in three hen genotypes (ISA Brown, Bovans Brown and Moravia BSL) on their laying performance and quality of their eggs.

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

Advanced Intelligent Discovery, EarlyView.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

A QTL for osteoporosis detected in an F2 population derived from White Leghorn chicken lines divergently selected for bone index [PDF]

, 2007
Osteoporosis, resulting from progressive loss of structural bone during the period of egg-laying in hens, is associated with an increased susceptibility to bone breakage.

Spatial Cell Death and Oxidative Stress Dynamics in Gas Plasma‐Treated Tumor Tissues

Advanced NanoBiomed Research, EarlyView.
Schematic representation of the four experimental models to study tissue penetration and oxidation. Four tissue models were used. Human pancreatic cancer cells were grown on the chorioallantois membrane of chicken embryos and gas plasma‐treated in ovo, murine colorectal tumor tissue was gas plasma‐exposed ex vivo, murine squamous cell carcinoma cells ...

Drying, a practical technology for reduction of poultry litter (environmental) pollution: methods and their effects on important parameters

Poultry Science
: Poultry farming generates significant poultry litter (broiler litter and laying hen manure), posing environmental and human health risks. Heat treatment, particularly through drying, can mitigate these adverse effects.

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Dietary Mannan‐Rich Fractions Attenuate Weaning Stress in Piglets via Modulating Gut Microbiota and TLR5/NF‐κB Signaling

Animal Research and One Health, EarlyView.
This study aimed to investigate the potential of a mannan‐rich fraction (MRF) as a dietary intervention to alleviate weaning stress in piglets. Our results revealed that MRF could alleviate weaning stress by modulating the gut microbiota and the TLR5/NF‐κB signaling pathway, offering a novel and sustainable alternative to antibiotic use in swine ...

Consumer perception and communication on welfare in organic laying hen farming [PDF]

, 2012
A major reason for increased societal popularity of organic production systems is the growing general discontent with intensive farming practices. However, urbanization leads to limited knowledge of farming and farm animal welfare.

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.
