Special Issue Information

Dear Colleagues,

The rapid advancement of technologies applied to ruminant nutrition and production has created new opportunities to improve animal performance, resource-use efficiency, product quality, and environmental sustainability. In recent years, the integration of innovative tools into nutritional and production systems has become essential to addressing global challenges such as climate change, feed efficiency, animal welfare, and sustainable livestock production.

For this Special Issue of AgriEngineering (MDPI), “New Technologies in Ruminant Nutrition and Production”, we aim to compile high-quality research and review articles that explore emerging technologies and novel approaches in ruminant systems. Topics of interest include, but are not limited to, precision nutrition, nutritional modeling, feed evaluation techniques, the use of functional additives, rumen microbiome modulation, biomarkers of intake and metabolism, sensor-based monitoring, data-driven decision tools, and advanced analytical methods. Studies addressing impacts on animal performance, health, product quality, and environmental outcomes are particularly encouraged. Original research articles and review papers are welcome in this Special Issue.

By bringing together cutting-edge research from different disciplines, we seek to provide a comprehensive and up-to-date perspective on how new technologies can contribute to more efficient, resilient, and sustainable ruminant production systems worldwide.

We look forward to receiving your contributions.

Kind regards,

Dr. Jarbas Miguel

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. AgriEngineering 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 1800 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.

Abstract
Winter feeding represents a significant cost in beef production, requiring efficient strategies that maintain productivity while minimizing environmental impact. Forty-six pregnant cows (620 ± 61 kg BW) were used to evaluate an ad libitum hay-based diet (2.02 Mcal/kg ME; HFOR; n = 23) [...] Read more.
Winter feeding represents a significant cost in beef production, requiring efficient strategies that maintain productivity while minimizing environmental impact. Forty-six pregnant cows (620 ± 61 kg BW) were used to evaluate an ad libitum hay-based diet (2.02 Mcal/kg ME; HFOR; n = 23) versus a corn-based diet (2.84 Mcal/kg ME) limit-fed at 1.2% BW (HCON; n = 23) from 50 d pre-calving to 84 d post-calving. Pre- and post-calving, HCON cows consumed less (p < 0.01) dry matter, crude protein, and water than HFOR cows. While CH4 yield per kg DMI was greater (p < 0.01) for HCON cows, total daily CH4 emissions and CH4 per unit of NEm intake were lower (p ≤ 0.03) compared with HFOR cows. Behavioral data showed that HCON cows had fewer (p < 0.01) meals and spent less time eating, but had greater intake per minute. Cow BW differed by treatment over time (p < 0.01), with HCON cows weighing less through early lactation, though no differences were observed from d 84 to weaning. Calf BW remained unaffected (p ≥ 0.76). In conclusion, limit-feeding a corn-based diet improves feed and water use efficiency and reduces enteric CH4 emissions without compromising calf growth, offering a viable alternative to traditional forage-based wintering systems.
