Seasonal, Strain and Hatch Effects on Egg Quality Traits

Poultry Science, 1957
ABSTRACT THE identification of specific genetic or environmental factors affecting the variation of egg quality traits should be of value in designing more accurate techniques for their evaluation in breeding operations. Strain differences in albumen quality are more easily detected than are those in shell quality, according to King and Hall (1955).

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.

INFLUENCE OF CAGE DENSITY ON EGG QUALITY TRAITS

Journal of Veterinary and Animal Sciences, 1999
Egg quality traits of White Leghorn strain cross layers (ILM-90) reared in three different floor densities viz., 420, 560 and700 cm2 per bird under cage system of rearing were evaluated. The results indicated that none of the egg quality traits studied in the experiment was influenced by the different floor space studied. Therefore a floor space of 420

EGG QUALITY TRAITS IN WG, GG AND GL JAPANESE QUAIL POPULATIONS

Trakia Journal of Sciences, 2019
The aim of the study was to evaluate egg quality traits in three heavy Japanese quail populations created and reared in the Poultry Breeding Unit of the Trakia University – Bulgaria, marked as WG, GG and GL. In the experiments, 160 female birds from populations WG and GG, and 96 birds from population GL were tested up to the 6th production month.

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

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.

Evaluation of Egg Quality Traits in Indigenous Chicken Breeds of India

Archives of Current Research International
Background: Egg quality traits are essential indicators of productivity, hatchability and consumer preference in poultry. Indigenous chicken breeds of India are known for their adaptability, resilience and unique product qualities, but comparative information on their egg characteristics under standardized conditions remains limited.

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

Animal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

Animal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Effects of Deinococcus spp. supplement on egg quality traits in laying hens

Poultry Science, 2018
To counter the ill effects of synthetic dyes, bacterial pigment production as an alternative is now one of the promising and emerging fields of research. This study was conducted to evaluate the applicability of Deinococcus genus on the egg quality traits in laying hens.
