Special Issue Information
Dear Colleagues,
Protein is often the first limiting nutrient when formulating diets for beef and dairy cattle. Protein is the major nitrogenous macronutrient of the diet and has structural, signaling and physiological functions. Models to estimate protein requirements for beef and dairy cattle, also called the metabolizable protein system, separate the requirements of ruminal microorganisms for nitrogenous components from the protein requirements of the host animal. Adequate characterization of rumen degradable protein, rumen undegradable protein and microbial protein, as well as the correct estimates of animal requirements for amino acids during different physiological stages (e.g., growth, gestation, lactation) is essential to improve nitrogen utilization in ruminants. The consequences of under- or over-overfeeding protein to ruminants goes beyond the economic viability of cattle operations, having environmental impacts such as the total reactive nitrogen loss (e.g., ammonia and nitrous oxide) in the atmosphere.
Due to the importance of protein nutrition for ruminants, this Special Issue aims to publish original research papers and literature reviews on protein and amino acid digestion, metabolism and utilization in ruminants, including the environmental aspects associated with nitrogen losses from beef and dairy production systems.
I invite you to share your recent findings through your contributions to this Special Issue.

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.
