The history of the feed industry is pertinent in terms of understanding how and why certain practices have evolved. Some of these practices have been superseded by modern, more natural alternatives, for example the traditional use of antibiotics in feed. In other cases, such as inorganic minerals, more natural versions akin to those found in plant and animal materials are available, although these new initiatives are still being taken up globally. Research continues to increase our knowledge and understanding of nutrient balance and digestion, and in some species this is more advanced than others. The following paper represents the first complete history of the feed industry, its major milestones, and projects how it might continue to utilise new technology developments to improve animal feeding practices.
