Construction and characterization of bioluminescent Reading outbreak and non-outbreak strains.

Unlabelled: enterica serotype Reading has recently been identified as a significant foodborne pathogen from contaminated poultry products. There is a critical need for close monitoring of this newly emerged pathogen. This study developed bioluminescent strains of Reading for real-time pathogen tracking using bioluminescence imaging.

Impact of trace mineral supplementation and translucency score on eggshell quality, hatchability, fertility, and chick quality.

The broiler breeder industry is facing a problem with fertility, hatchability, and the number of broiler breeder eggs produced per hen. The supplementation of trace minerals such as zinc, manganese, and copper in broiler breeder diets has been previously linked to an increase in eggshell quality, which may lead to increased fertility, hatchability, and chick quality. The objective of this study was to explore the effect of amino-acid complexed mineral supplementation on eggshell quality, fertility, hatchability, chick quality, and shell translucency.

A Longitudinal Study on Campylobacter spp. in an Integrated Broiler Complex in the Southeast Region of the United States: Prevalence and Phylogenetic Analysis.

Poultry meat products are considered the major contributors to Campylobacteriosis in humans. The objective of this study was to determine the prevalence status, critical entry points, and movement patterns of Campylobacter spp. along different stages of an integrated broiler complex.

Response of YPM x Ross 708 male broilers to diets containing varying inclusions of phytase, calcium butyrate, and bacitracin methylene disalicylate from 1 to 42 d of age-part 1: performance, processing yields, and nutrient digestibility.

This 42-d study evaluated the effects of phytase, calcium butyrate (CB), and bacitracin methylene disalicylate 50 (BMD) on broiler performance, processing yields, and nutrient digestibility. Ross YPM x 708 male broilers (2,880 total) were distributed in 72 floor pens and assigned to 1 of 9 treatments (8 replicates/treatment) on d of hatch. This experiment was a 2 × 4 + 1 factorial arrangement, including 2 phytase concentrations (500 or 1,500 FTU/kg), 4 microbiota modulating feed additive groups (MMFA; none, CB (0.

Campylobacter jejuni from no antibiotics ever (NAE) broilers: prevalence, antibiotic resistance, and virulence genes analysis.

Campylobacter jejuni (C. jejuni) is a leading foodborne illness causing bacteria, and poultry is a major reservoir of this pathogen. With the recent increase in broiler production under the "no antibiotics ever" (NAE) system, this study aimed to assess the prevalence, antibiotic resistance, and virulence characteristics of C.
