Special Issue Information

Dear Colleagues,

This Special Issue aims to highlight recent advances in microbial and bioprocessing strategies that enhance rumen function, feed efficiency, and sustainability in ruminant production systems. Research focusing on the manipulation of rumen microbiota, the use of microbial feed additives, enzyme supplementation, and feed pretreatments through physical, chemical, or biological processes is particularly welcome. Emphasis will be placed on studies exploring microbial ecology, fermentation kinetics, nutrient conversion efficiency, and the mitigation of anti-nutritional factors or environmental emissions. Both in vitro and in vivo investigations addressing the integration of biotechnology and microbial innovation to improve feed degradability and animal performance are encouraged. This Special Issue seeks to provide a comprehensive overview of cutting-edge approaches contributing to sustainable ruminant nutrition, enhanced animal productivity, and reduced environmental impact through advanced microbial and bioprocessing technologies. As Guest Editors of this Special Issue, we warmly invite researchers to contribute perspective articles, original research papers, review articles, and short communications.

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. Ruminants is an international peer-reviewed open access quarterly 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 1200 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.

Edible trees, such as Bordão-de-velho (BVP; Samanea tubulosa), are being studied for their nutritional potential and the presence of bioactive compounds that influence ruminal fermentation. This study aimed to evaluate, using an in vitro assay, the effects of increasing the inclusion of BVP pods in dairy cow diets formulated with different energy levels. The experiment was conducted with eight treatments obtained from a 4 × 2 factorial arrangement, containing four levels of pod inclusion (0, 100, 200, and 300 g/kg dry matter) and two dietary energy levels (high and low). Increasing BVP levels resulted in a linear reduction in gas production from digestible organic matter in low-energy diets, without altering dry matter and organic matter digestibility or methane production. There was an increase in pH and in the acetate/propionate ratio, along with a reduction in the concentrations of short-chain fatty acids and isoacids. In conclusion, Samanea tubulosa pods improve fermentation efficiency and reduce gas production, making them a promising forage source for low-productivity animal diets. Full article
