Ontogeny of hepatic metabolism in two broiler lines divergently selected for the ultimate pH of the Pectoralis major muscle
<p>Nutrient availability during early stages of development (embryogenesis and the first week of life) can have long-term effects on physiological functions and bird metabolism. The embryo develops in a closed structure and depends entirely on the nutrients and energy available in the egg. The aim of this study was to describe the ontogeny of pathways governing hepatic metabolism that mediates many physiological functions in the pHu+ and pHu- chicken lines, which are divergently selected for the ultimate pH of meat, a proxy for muscle glycogen stores, and which differ in the nutrient content and composition of eggs. Our study provides the first detailed description of the evolution of different hepatic metabolic pathways during the early development of embryos and post-hatching chicks. We found a metabolic orientation for the pHu+ line towards proteolysis, glycogen degradation, ATP synthesis and autophagy, likely in response to a higher energy requirement compared with pHu- embryos. The metabolic orientations specific to the pHu+ and pHu- lines are established very early, probably in relation with their different genetic background and available nutrients.</p>
Growth, nutrient uptake, blood metabolites and bone properties in broilers consuming feed with mineral-enriched whole black soldier fly larvae
<p>Recycling critical minerals like phosphorus is essential for future circular agriculture. This study explored adding mineral-enriched black soldier fly larvae (BSFL), grown on substrates with sewage sludge recyclates (SSR), to broiler feed to reintroduce minerals from restricted waste streams into the nutrient cycle. Results showed that including 15% mineral-enriched BSFL in broiler diets for 42 days had no adverse effects on growth, nutrient intake, or bone condition, and maintained acceptable levels of heavy metals.</p>
Diet-induced changes in the jejunal microbiota of developing broilers reduce the abundance of Enterococcus hirae and Enterococcus faecium

Kar, Norbert Stockhofe, Vera Perricone, Johanna M. J. Rebel, Ingrid C. de Jong, Alex Bossers </p><p> </p><p>Modern broiler breeds allow for high feed efficiency and rapid growth, which come at a cost of increased susceptibility to pathogens and disease. Broiler growth rate, feed efficiency, and health are affected by the composition of the gut microbiota, which in turn is influenced by diet. In this study, we therefore assessed how diet composition can affect the broiler jejunal gut microbiota. A total of 96 broiler chickens were divided into four diet groups: control, coated butyrate supplementation, medium-chain fatty acid supplementation, or a high-fibre low-protein content. Diet groups were sub-divided into age groups (4, 12 and 33 days of age) resulting in groups of 8 broilers per diet per age. The jejunum content was used for metagenomic shotgun sequencing to determine the microbiota taxonomic composition at species level. The composed diets resulted in a total of 104 differentially abundant bacterial species. Most notably were the butyrate-induced changes in the jejunal microbiota of broilers 4 days post-hatch, resulting in the reduced relative abundance of mainly <i>Enterococcus</i> <i>faecium</i> and the opportunistic pathogen <i>Enterococcus</i> <i>hirae</i>, when compared to the control diet. This effect takes place during early broiler development, which is critical for broiler health, thus exemplifying the importance of how diet can influence the microbiota composition and its relation to broiler health. Future studies should therefore elucidate how diet can be used to promote a beneficial microbiota in the early stages of broiler development.</p>
Phyloseq 16S v3v4 object accompanying paper: Host genotype affects endotoxin release in excreta of broilers at slaughter age
<p>This ready to load <strong>phyloseq</strong> R S4 object contains the ASV table, taxonomy table and sample metadata. This data was build using the DaDa2 (version 1.18.0) and phyloseq (version 1.34.0) R packages using the SILVA 138.1 nr99 database and raw MiSeq PE300 sequencing data deposited at NCBI-SRA under BioProject: PRJNA975731.</p> <p>F. Marcato, J.M.J. Rebel, S.K. Kar, I. Wouters, D. Schokker, A. Bossers, F. Harders, J.W. van Riel, M. Wolthuis-Fillerup and I.C. de Jong. </p> <p>The main goal of the current study was to investigate whether or not it was possible to modulate the fecal microbiome and thereby reducing endotoxin concentrations in the excreta of broiler chickens. An experiment was carried out with a 2 x 2 x 2 factorial arrangement including 3 factors, 1) genetic strain (fast-growing Ross 308 vs. slower-growing Hubbard JA757), 2) no vs. combined use of probiotics and prebiotics in the diet and drinking water, 3) early feeding at the hatchery vs. non early feeding. A total of 624 Ross 308 and 624 Hubbard JA757 day-old male broiler chickens were included until d 37 and d 51 of age, respectively. Broilers (26 chicks per pen) were housed in a total of 48 pens, and there were 6 replicate pens/treatment group. Pooled cloacal swabs (10 chickens per pen) for microbiome and endotoxin analyses were collected at a target body weight (BW) of 200 g, 1 kg and 2.5 kg.</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.
