Comprehensive Characterization of Acer truncatum Leaf Extract: Identification of Systemic Metabolites and Effects on Performance, Antioxidant Status, and Intestinal Microbiota in Laying Hens

Animal Research and One Health, EarlyView.
Dietary A. truncatum leaf extract is absorbed and improves laying performance in aged hens by enhancing systemic antioxidant capacity and modulating the gut microbiota. ABSTRACT The demand for natural feed additives is considerably increasing in the antibiotic‐free feed era.

The welfare of broiler breeders

Animal Welfare, 1999
In August 1998, the UK's Farm Animal Welfare Council (FAWC) published its most recent report: addressing the welfare of broiler breeders. Some 780 million broiler chicks are produced annually in the UK and at any one time the national population of broiler breeder hens that produce these chicks is about 6 million.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Longitudinal study on background lesions in broiler breeder flocks and their progeny, and genomic characterisation of Escherichia coli

Veterinary Research, 2022
In broiler breeders, background mortality is rarely addressed, however, it represents the death of a vast number of birds, a constant productivity loss, welfare concerns and it might affect chick quality.

Comparative Analysis of Salmonella typhimurium‐Induced Transcriptomic Changes in the Spleen of Beijing‐You Chickens and Guang Ming Broilers

Animal Research and One Health, EarlyView.
This study analyzed the spleen transcriptomes of different chicken breeds, identified key differentially expressed genes (EGR1, FOS, and DUSP1) that regulate resistance to Salmonella infection, and elucidated the underlying regulatory mechanisms, thereby providing new targets for disease‐resistant breeding in poultry.

Effects of an Organic Acid Blend on Growth Performance, Redox Homeostasis, and Intestinal Microbiota of Broilers in an Antibiotic‐Free Production System Under Winter Environmental Challenges

Animal Research and One Health, EarlyView.
Schematic summary of the effects of organic acids on growth performance and gut health‐related parameters in broilers. ABSTRACT This study was conducted to evaluate the effects of an organic acid blend on growth performance, redox homeostasis, and intestinal microbiota of broilers raised in an antibiotic‐free system during the winter season in China ...

Exploring the Role of Competitiveness in Sustainability Standards: Insights From an Animal Welfare Scheme Adopted by Supermarkets

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Research on supermarket‐related voluntary sustainability standards (VSSs) is divided on whether competition helps or hinders efforts to reduce negative social and environmental impacts. This paper examines how the standardization process shapes these outcomes.
