In-vitro selection of lactic acid bacteria to combat Salmonella enterica and Campylobacter jejuni in broiler chickens
<p><em><span>In-vitro</span></em><span> selection of LAB strains for antimicrobial applications in livestock production required specific focus on certain LAB strains. Accordingly, six commercial LAB strains (homofermentative, obligatory heterofermentative and facultative heterofermentative) belonging to different genera, were chosen for screening against strains of <em>Salmonella </em>and <em>Campylobacter jejuni </em>under <em>in-vitro </em>conditions.</span></p> <p> </p>

<p><span>The current study was conducted to validate the effects of <em>in-ovo </em>application of the selected prophybiotic (<em>L. mesenteroides + </em>garlic aqueous extract) as opposed to the use of probiotics alone on the gut health and production parameters of ROSS308 broiler chickens. <span> </span>To our knowledge, our study is the first to use a prophybiotic combination as well as a <em>Leuconostoc mesenteroides </em>strain in an <em>in-ovo </em>application in poultry.</span></p>
Modulation of gene expression in immune related organs by in-ovo stimulation with probiotics and prophybiotics in broiler chickens
<p><span>The current study was performed to further investigate the tissue specific immune modulation and metabolic gene regulation of these <em>in-ovo</em> stimulated chickens. Accordingly, the expression of immune related genes was determined in the secondary immune organs, cecal tonsils and the spleen as well as the liver which is an important organ for both the immune system and metabolism. Additionally, the expression of the genes related to metabolism was also analyzed in the liver.</span></p>
Time-series transcriptome analysis identified differentially expressed genes in broiler chicken infected with mixed Eimeria species
<p>Coccidiosis caused by the <em>Eimeria</em> species is a highly problematic disease in the chicken industry. Here, we used RNA sequencing to observe the time-dependent host responses of <em>Eimeria</em>-infected chickens to examine the genes and biological functions associated with immunity to the parasite. Transcriptome analysis was performed at three time points: 4, 7, and 21 days post-infection (dpi). Based on the changes in gene expression patterns, we defined three groups of genes that showed differential expression. This enabled us to capture evidence of endoplasmic reticulum stress at the initial stage of <em>Eimeria</em> infection. Furthermore, we found that innate immune responses against the parasite were activated at the first exposure; they then showed gradual normalization. Although the cytokine-cytokine receptor interaction pathway was significantly operative at 4 dpi, its downregulation led to an anti-inflammatory effect. Additionally, the construction of gene co-expression networks enabled identification of immunoregulation hub genes and critical pattern recognition receptors after <em>Eimeria</em> infection. Our results provide a detailed understanding of the host-pathogen interaction between chicken and <em>Eimeria</em>. The clusters of genes defined in this study can be utilized to improve chickens for coccidiosis control.</p>
Demographics for all four breeds of broiler chickens
<p><span>In 2018, over nine billion chickens were slaughtered in the United States. As the demand for chickens increases, so too have concerns regarding the welfare of the chickens in these systems and the damage such practices cause to the surrounding ecosystems. To address welfare concerns, there is large-scale interest in raising chickens on pasture and switching to slower-growing, higher-welfare breeds as soon as 2024. We created a box model of US chicken demographics to characterize aggregate broiler chicken welfare and land use consequences at the country scale for US shifts to slower-growing chickens, housing with outdoor access, and pasture management. The US produces roughly 20 million metric tons of chicken meat annually. Maintaining this level of consumption entirely with a slower-growing breed would require a 44.6%–86.8% larger population of chickens and a 19.2% – 27.2% higher annual slaughter rate, relative to the current demographics of primarily "Ross 308" chickens that are slaughtered at a rate of 9.25 billion per year. Generating this quantity of slower-growing breeds in conventional concentrated animal feeding operations (CAFO) would require 90,582-98,687 km2, an increase of 19.9-30.6% over the 75,577 km2 of land used for current production of Ross 308. Housing slower-growing breeds on pasture, the more individually welfare-friendly option, would require </span><span>108,642-121,019 km2, a 43.8-60.1% increase over current land use. Allowing slower-growing breeds occasional outdoor access is an intermediate approach that would require 90,691-98,811 km2, an increase of 20-30.7% of the current land use, a very minor increase of land relative to managing slower-growing breeds in CAFOs. In sum, without a drastic reduction in consumption, switching to alternative breeds will lead to a substantial increase in the number of individuals killed each year, an untenable increase in land use, and a possible decrease in aggregate chicken welfare at the country-level scale. Pasture-based management requires substantial additional land use. These results demonstrate constraints and trade-offs in animal welfare, environmental conservation, and food animal consumption, while highlighting opportunities for policies to mitigate impacts in an integrated manner using a One Health approach.</span></p>

Data from: Widespread introgression in Chinese indigenous chicken breeds from commercial broiler
Chinese indigenous chickens constitute world-renowned genetic resources due to their excellent traits, including early puberty, good meat quality, and strong resistance to disease. Unfortunately, the introduction of a large number of commercial chickens in the past two decades has had an adverse effect on Chinese indigenous chickens. Using the chicken 60K single-nucleotide polymorphism (SNP) chip, we assessed the genetic diversity and population structure of 1,187 chickens, representing eight Chinese indigenous chicken breeds, two hybrid chicken breeds, two ancestral chicken breeds, two commercial populations, and additional red jungle fowl. By investigating haplotype similarity, we found extensive gene introgression from commercial broiler to almost all Chinese indigenous chickens. Approximately 15% of the genome, on average, of Chinese indigenous chickens was introgressed, ranging from 0.64% for Tibetan chicken to 21.52% for Huiyang Bearded chicken. Further analysis revealed signals consistent with positive selection in the introgression loci. For the first time, we systematically mapped and quantified introgression from commercial broiler to Chinese indigenous chickens at the whole genome level. Our data provided a usable resource for chicken genetic diversity, and our findings indicated a dire need for protecting the genetic resources of Chinese indigenous chickens.
