Virtual Issue: Plants and extracts rich in secondary metabolites: their utility in ruminant nutrition

After the ban of the use of feed antibiotics in many countries, and owing to consumers’ concerns, the search for diet supplementation with natural bioactive compounds is in the focus of research. In ruminant nutrition, such compounds are either supplemented in purified form or via entire plants, plant parts or crude extracts thereof. There is a tremendous wealth of possibly suitable sources, especially in the tropics. This makes the search for useful supplements exciting, but also difficult. In addition to that, natural products have a rather large variability in their properties as a consequence of both variations in concentration and chemical composition of secondary compounds. The biggest challenge is, therefore, to identify supplements with consistently positive effects on performance, animal health and digestion, the latter favourably associated with low methane emissions. This virtual issue of the Journal of Animal Physiology and Animal Nutrition compiles recent findings in this field. The studies comprised various plant secondary compounds among them tannins, saponins, terpenes and sulphur-containing compounds. It demonstrates the broad range of research approaches currently applied in this field.
