Special Issue Information

Dear Colleagues,

Ensuring the optimal health of monogastric animals is imperative to enhance production efficiency, improve animal welfare, and ultimately meet the demands of global food security within a sustainable framework. Certainly, proper nutrition and well-planned feeding strategies are essential to achieve success in this task. By providing balanced diets tailored to precisely meet animal nutritional requirements, producers can maximize nutrient-use efficiency and elevate the quality of derived animal products while concurrently mitigating adverse environmental impacts; however, feed may have an even more significant impact. Certain feed constituents have the potential to improve gut health, modulate immune responses, diminish disease prevalence, and mitigate antibiotic use.

This Special Issue provides space for original research papers that address the use of nutritional strategies, functional ingredients, or feed additives to maximize the health of monogastric animals. Papers addressing strategies to reduce the use of antibiotics or novel techniques to assess the effects of nutritional health solutions (such as gut health biomarkers) are also invited.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences 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 2100 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.

The objective of this study was to evaluate the effects of partially replacing wheat bran with poplar wood composite fiber (PWCF) on growth performance, immune status, apparent total tract digestibility (ATTD), and gut microbial composition in growing pigs. A total of 140 healthy crossbred (Duroc × Landrace × Yorkshire) growing pigs with an initial body weight of 47.25 ± 0.49 kg were randomly assigned to two dietary treatments, with five replicates per treatment and fourteen pigs per replicate. The control (CT) group was fed a corn–soybean meal-based diet containing wheat bran and rice bran meal, whereas the experimental group received the same diet in which 2% wheat bran was replaced by PWCF. The experiment lasted for 60 days. Compared with the CT group, replacing wheat bran with PWCF did not affect body weight, average daily feed intake, feed conversion ratio, or average daily gain on days 30 or 60 (p > 0.05). In addition, no negative effects were observed on ATTD of nutrients and serum immunoglobulin A (IgA), IgG, and IgM levels at either time point, indicating that PWCF can serve as a suitable partial substitute for wheat bran in growing pig diets. However, it could regulate nitrogen metabolism by reducing blood urea nitrogen (BUN) concentration and the BUN/creatinine ratio, as well as decreasing total free amino acids in serum (p < 0.05). In addition, the antioxidant capacity can be transiently improved by increasing catalase activity. Gut microbiota analysis showed that the replacement significantly increased the relative abundances of Treponema, the Lachnospiraceae_XPB1014_group and Prevotellaceae_UCG-001 (p < 0.05). These changes suggest that PWCF modulates gut microbiota and enriches fiber-degrading bacterial populations. Overall, substituting wheat bran with PWCF did not impair growth performance, immunity, or digestibility, while altering microbial community composition. These findings support the potential application of PWCF as an alternative fiber source, contributing to greater diversity in feed formulation. Full article
