Special Issue Information

Dear Colleagues,

Nutritional strategies in livestock production have increasingly focused on elucidating the intricate mechanisms by which dietary factors influence biological pathways to enhance animal performance. Omics technologies—encompassing genomics, transcriptomics, proteomics, metabolomics, and microbiomics—represent cutting-edge tools that enable a deeper understanding of physiological processes and phenotypic traits related to productivity and health in livestock.

The integration of these advanced technologies into nutrition science, known as nutriomics, provides novel approaches to optimize feeding strategies and enhance the efficiency of livestock systems, particularly in pigs and poultry. As the global livestock industry faces mounting challenges—such as climate change, animal welfare concerns, and feed ingredient shortages—there is an urgent need to unravel the complex interactions between nutrition, genetics, metabolism, and the environment.

This Special Issue aims to highlight recent advances in the application of nutriomics to enhance pig and poultry production. We welcome original research articles, reviews, and case studies that provide new insights into nutritionally driven molecular responses and the development of precision feeding strategies grounded in omics-based evidence.

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 250 words) can be sent to the Editorial Office for assessment.

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. Animals is an international peer-reviewed open access semimonthly 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 2400 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.

This study was conducted to elucidate the molecular and metabolic differences in ileal development according to birth weight in neonatal piglets. A total of 126 neonatal piglets born from Yorkshire × Landrace × Duroc crossbred sows were used, and the top 5% (H group, 1.77 ± 0.02 kg) and bottom 5% (L group, 0.72 ± 0.03 kg) of birth weights were selected for analysis. Ileal tissues were collected for transcriptomic (RNA-seq) and targeted metabolomic (GC–MS) analyses, and selected genes were validated using RT-qPCR. A total of 112 differentially expressed genes (DEGs) were identified, among which RFC3, PCNA, MCM3, MCM10, AURKA, AURKB, CCNB2, CCNA2, CCNF, and SI were significantly upregulated in the H group (p < 0.05). These genes were mainly involved in pathways related to DNA replication, cell division, and nutrient digestion and absorption. In addition, metabolomic analysis revealed that pyruvic acid concentrations were significantly higher in the H group (p < 0.05), indicating the activation of energy metabolic pathways. These results indicate that high-birth-weight piglets possess a genetic foundation for enhanced cellular proliferation and energy metabolism, and they further highlight potential molecular targets for improving growth performance and intestinal development in low-birth-weight piglets.
