Special Issue Information

Dear Colleagues,

The overarching goal of this Special Issue is to provide an in-depth review of the current knowledge on protein metabolism across stages of the life cycle in avian, swine, equine, feline, and canine species.  The emphasis will be to highlight and discuss the idiosyncrasies in protein and amino acid metabolism that dictate the animal’s dietary amino acid requirements. Topics will include a fundamental understanding of uric acid metabolism in avian species for prediction of amino acid needs, the potential impact of feed ingredients on taurine availability and methionine requirement of dogs and dilated cardiomyopathy, nitrogen recycling in the large intestine and its impact on the microbiota in equine species, the impact of fiber nutrition on protein digestibility and amino acid availability in gestating and lactating sows, the interaction between amino acid availability and fiber nutrition in the newly weaned piglet, and the interactions between carbohydrates and protein nutrition of felids.

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.

Pigs are among the most important farm animals for meat production worldwide. In order to meet the amino acid requirements of the animals, pigs rely on the regular intake of proteins and amino acids with their feed. Unfortunately, pigs excrete about two thirds of the used protein, and production of pork is currently associated with a high emission of nitrogen compounds resulting in negative impacts on the environment. Thus, improving protein efficiency in pigs is a central aim to decrease the usage of protein carriers in feed and to lower nitrogen emissions. This is necessary as the supply of plant protein sources is limited by the yield and the cultivable acreage for protein plants. Strategies to increase protein efficiency that go beyond the known feeding options have to be investigated considering the characteristics of the individual animals. This requires a deep understanding of the intestinal processes including enzymatic activities, capacities of amino acid transporters and the microbiome. This review provides an overview of these physiological factors and the respective analyses methods. Full article
