Quantitative trait loci for bone traits segregating independently of those for growth in an F-2 broiler X layer cross [PDF]

, 2007
An F-2 broiler-layer cross was phenotyped for 18 skeletal traits at 6, 7 and 9 weeks of age and genotyped with 120 microsatellite markers. Interval mapping identified 61 suggestive and significant QTL on 16 of the 25 linkage groups for 16 traits.

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.

High-throughput in vivo phenotyping of chicken carcass traits based on digital radiographic imaging

Journal of Animal Science and Biotechnology
Background Accurate phenotyping of breast, drumstick, and wing yield is essential for genetic improvement in poultry breeding. However, these key economic traits can traditionally be measured only after slaughter, forcing breeding programs to rely on ...

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

Potential Application of Saccharomyces cerevisiae as an Antioxidant Agent for Broiler Chickens – A Brief Overview [PDF]

Journal of Applied Veterinary Sciences
Broiler chicken strains and the intensive production system are typically attributed to the stress conditions in broiler production. The use of synthetic antioxidants is commonly practiced by the farmers to alleviate the adverse effects of stress on ...

The effects of supplemental levels of inorganic zinc, manganese and copper on growth performance in commercial broilers

Animal, 2021
Commercial broiler premixes provide trace minerals (TMs) such as Zinc (Zn), Manganese (Mn) and Copper (Cu) above the birds' requirements to maximise broiler performance.

Darkling beetles (Alphitobius diaperinus) and their larvae as potential vectors for the transfer of Campylobacter jejuni and Salmonella enterica serovar paratyphi B variant Java between successive broiler flocks [PDF]

, 2008
Broiler flocks often become infected with Campylobacter and Salmonella, and the exact contamination routes are still not fully understood. Insects like darkling beetles and their larvae may play a role in transfer of the pathogens between consecutive ...

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

Animal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

A Review on Heat Stress in Broiler Chickens: Mechanisms, Effects and Mitigation Strategies. [PDF]

Vet Med Sci
Heat stress caused by high temperature and humidity compromises broiler health, welfare, and productivity by reducing feed intake, growth performance, and feed efficiency, while increasing mortality, oxidative stress, metabolic disturbances, intestinal dysfunction, gut dysbiosis, immune suppression, and meat quality deterioration.
