Special Issue Information

Dear Colleagues,

There are many challenges affecting poultry production worldwide. It is important that we evaluate the factors that affect ingredient utilization, nutrition, metabolism, and feed processing in poultry. The poultry industry is also facing an urgent need to innovate in relation to nutritional requirements and enhanced sustainability.

We invite colleagues to share their ongoing work, in the form of research papers, in this Special Issue of Metabolites, which will focus on the most challenging areas in commercial poultry production, exploring recent advances in nutrition, metabolism, and cost-effective diets to improve feed efficiency. Topics of interest include, but are not limited to, the following:

  • Current challenges in poultry production and sustainability;
  • Quality of ingredients in poultry feed;
  • Factors affecting nutrition and intestinal health;
  • Methods of evaluating health parameters and nutrient utilization;
  • Recent advances in poultry requirements;
  • Energy and nutrient digestibility;
  • Nutrition and metabolism affecting meat and egg quality;
  • Factors affecting the metabolism of carbohydrates, protein, and lipids;
  • Feed processing and feed quality;
  • Nutritional aspects influencing poultry progenies;
  • Feed additives for broilers, breeder hens, and layers.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metabolites is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Background/Objectives: The use of black soldier fly (BSF) larvae meal in poultry nutrition is gaining attention as a sustainable protein source with a high nutritional value, an efficient bioconversion of organic waste, and potential functional benefits for intestinal health. This study evaluated the dietary effects of including 5% BSF larvae meal on the growth performance, nutrient digestibility, and energy utilization as well as on the intestinal integrity, gene expression, lipid profile, and short-chain fatty acid (SCFA) production of broilers under an intestinal challenge. Methods: Eight hundred one-day-old male broilers were assigned to four dietary treatments with eight replicates (25 birds/pen) and reared until day 40. Birds were fed either a Basal corn–soy diet or a BSF diet (5% BSF larvae meal replacing energy- and protein-yielding ingredients). Diets were provided to a non-challenged group and a challenged group, which was orally gavaged with Eimeria spp. on day 1 and Clostridium perfringens on days 11 and 14. The growth performance was evaluated up to day 40, while the nutrient digestibility, meat lipid profile, intestinal histomorphology, and gene expression were assessed at 21 days. The SCFAs were determined at both 21 and 40 days. Results: It was observed that the intestinal challenge induced dysbiosis and negatively affected growth performance, whereas the BSF meal inclusion partially mitigated these adverse effects. Broilers fed the BSF larvae meal showed increased cecal SCFA concentrations and a lower interleukin-6 gene expression, along with higher lauric and myristic acid levels in breast muscle (p ≤ 0.05). Conclusions: The inclusion of 5% BSF larvae meal improved performance without impairing nutrient digestibility or intestinal histomorphology, while increasing cecal concentrations of butyric and acetic acids and promoting a beneficial lipid deposition.
