Special Issue Information

Dear Colleagues,

In our rapidly changing world, affected by environmental and climate issues, there is a constant need to improve the quality of animal products and the efficiency of animal production in order to feed a rapidly growing population. This can only be achieved through high-quality scientific research and dissemination over time of acquired knowledge. The key element in sustainable animal production to meet the increased demand for high-quality, safe and easily accessible food is animal nutrition, which affects almost every sector of animal production: animal productivity and reproduction, the quality and safety of animal products, health and animal welfare, farm economic viability and environmental protection.

The aim of the current Special Issue is to publish high-quality original scientific articles, paying special (but not exclusively) attention to the following topics: the effect of animal nutrition and feeding strategies on the efficiency and sustainability of animal production systems; nutritional quality and content in bioactive compounds of products of animal origin; novel approaches and strategies in the nutrition and feeding of animals in the context of climate change; advances in novel animal alternative feed; exploring the use of innovative prebiotics, probiotics, natural extracts and by-products in non-ruminant feeding. In addition, this Special Issue encourages the simultaneous development of innovative feeding strategies aimed at improving animal welfare and health, as well as reducing environmental pollution on animal farms.

Both reviews and original research papers are welcome in this Special Issue. Reviews should be closed with an outlook, open questions and directions for future research.

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.

The inevitable enteric gas emission from ruminants is considered a modern-day problem from an environmental perspective. Addressing this problem requires nutritional approaches such as the use of phytogenic additives in ruminant diets. In this regard, lupin seed (LS) can be a useful additive due to its phytochemical constituents. Therefore, this study investigated the effects of lupin (Lupinus angustifolius) seed supplementation as a functional and sustainable feed additive in sheep diet (50:50 concentrate-to-forage ratio) on in vitro gas production (GP; mL/g DM), methane (CH4; mL/g DM) and carbon dioxide (CO2; mL/g DM) emissions, fermentation parameters, and nutrient degradability (g/kg DM incubated). Gas production and CH4 were measured per gram of incubated dry matter (DM), degradable DM (dDM), degradable neutral detergent fiber (dNDF), and degradable acid detergent fiber (dADF). Lupin seeds were included at 0 (control), 0.5, 1.0, 1.5, and 2% of the diet. The seeds contained 3.27% essential oils (DM basis), with eucalyptol as the main phytochemical. The highest GP per gram of DM and dDM was observed (p < 0.01) with 2.0% LS supplementation level. While 1.0% LS had the highest GP per gram of dNDF, 0.5% lupin diet had the highest GP per gram of dADF. Asymptotic GP and CH4 emissions linearly and quadratically increased (p < 0.01) with increasing LS level, while lag time decreased. Despite increased CH4 production, the proportion of CH4 in total biogas was lower (p = 0.008) for LS treatments than the control, with the 0.5% LS showing the lowest CH4 proportion. Production of CO2 increased with lupin seed treatments, with 0.5% LS producing the highest proportion (p = 0.027). Degradability of DM, NDF, and ADF was greater (p < 0.01) for the high LS supplementation level, while 0.5% supplementation level decreased ADF degradability. Total short-chain fatty acids, acetic acid, and propionic acid increased (p < 0.05) with LS supplementation level, leading to a reduced acetate:propionate ratio. Rumen pH decreased (p = 0.036) with LS supplementation, while ammonia-N decreased (p = 0.045) and estimated metabolizable energy increased (p < 0.001) linearly. Calculated microbial protein synthesis (p = 0.005) and gas yield (p = 0.047) increased with LS supplementation level. LS supplementation at 2.0% of diet (DM basis) increased GP and CH4 emission (mL/g DM) and enhanced nutrient degradability, suggesting its potential use as a functional feed additive for ruminants when supplemented at a 2.0% level into diet.
