Special Issue Information

Dear Colleagues,

Research on lipid nutrition in monogastric animals, such as swine, poultry, canines, and felines, is essential for enhancing growth performance, improving health, and ensuring the production of high-quality animal products. As global demand for animal protein and optimal companion animal nutrition continues to rise, optimizing lipid nutrition through ongoing research is critical for promoting sustainable and efficient production practices for monogastric species, including livestock and pets.

This Special Issue will serve as a forum for presenting the latest findings on lipid nutrition across monogastric species, covering key areas such as (1) Growth Performance and Feed Efficiency, (2) Health and Immune Function, (3) Meat Quality, (4) Environmental Impact, and (5) Nutrient Interactions.

We invite contributions that push the boundaries of knowledge in lipid nutrition and metabolism in monogastric animals and encourage the submission of original research papers and comprehensive literature reviews.

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. 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.

Different energy sources are often used in horse diets to enhance health and performance. Understanding how diet impacts the cecal and fecal microbiota is crucial for meeting the nutritional needs of horses. High-throughput sequencing and qPCR were used to compare the fecal and cecal microbiota of five healthy horses receiving three different diets: hay diet (HAY), hay + starch and sugar (SS), and hay + fiber and oil ingredients (FO). Assessment of short-chain fatty acids, pH, and buffer capacity was also performed. The HAY diet was associated with the highest values of fecal pH; the FO and SS diets were associated with higher values of BC6 in the cecum, and the SS diet had higher BC5 values in feces (p < 0.05). HAY was associated with a lower alpha diversity in feces and with a higher abundance of Treponema, Fibrobacter, Lachnospiraceae AC2044, and Prevotellaceae UCG-003 in feces. SS was associated with a higher abundance of Desulfovibrio, the Lachnospiraceae AC2044 group, and Streptococcus in the cecum, and Streptococcus and Prevotellaceae UCG-001 in feces, while FO was associated with higher Prevotella, Prevotellaceae UCG-003, and Akkermansia in the cecum, and the Rikenellaceae RC9 gut group and Ruminococcus in feces. This study indicated that different energy sources can influence cecal and fecal microbiota composition and fecal diversity without significantly affecting fermentation processes under experimental conditions. These findings suggest that the diets studied may not pose immediate health risks; however, further research is needed to generalize these effects on gastrointestinal microbiota in broader equine populations.
