Sustainable Feeds for Animal Nutrition in Tropical Areas

Developing efficient feeds and sustainable feeding systems is required to meet the increasing demand for livestock and livestock products [1]. Therefore, one of the main objectives in animal nutrition is to explore alternative feeds and investigate their impact on animal performance and the quality of their products. In tropical areas, there are many opportunities to explore, including the use of herbs and legumes as feed additives and the improvement of grazing management on native heterogeneous vegetation. We summarize the studies published in this Special Issue on recent advances in animal nutrition in tropical areas. These studies addressed the nutritional value assessment of climate-resilient forage and tree seeds, with a review of interventions to improve feed efficiency; alternative feeds and feed additives such as legumes seeds, leaves and processing by-products on fermentation characteristics, and methane production; animal performances and health; and meat quality.
