Feed additives are shown to be an effective part of mitigating various challenges in poultry production and supporting animal health as well as performance. There are several types of feed additives such as phytogenics, probiotics, prebiotics, postbiotics, etc. that are used in the industry. Each of these feed additives has a specific mode/s of action and can be an effective part of the holistic strategy to support sustainable animal production. However, when used alone, the benefits could vary across different conditions. The more we know about the mode/s of action of these feed additives, the more we realize that just using one type of feed additive might not give us consistent benefits. Understanding the mechanism of action of various feed additives and combining the ones with synergistic benefits can give better value and consistency across different production systems.
Science-based feed additive combination for consistent benefits A successful combination of two different platforms of feed additives available for broilers is Biostrong™ Dual, also known as MB Pro. It provides synergistic benefits of a postbiotic, Saccharomyces cerevisiae fermentation product (SCFP), and a proprietary blend of essential oil compounds (EOC). Postbiotics are produced from a controlled fermentation process and they typically contain inanimate cells/cell fragments and metabolites that are beneficial to the host. The main modes of action of SCFP are modulating the immune response and supporting the beneficial microbes in the gut. The advantage of using postbiotics over other categories of feed additives is it’s a stable mix of ready-to-be-utilized metabolites which can provide consistency in ingredient functionality and animal response. On the other hand, the EOCs are substances that are either of psychogenic origin or produced through synthetic processes. The main modes of action of EOC are they can improve digestive enzymatic activity and help manage undesirable bacteria in the gut. So, combining SCFP and EOC in one product can have synergistic effects leading to better protection throughout the gastrointestinal tract of the animal.
Biostrong™ Dual is not just any combination of two feed additive platforms. A lot of science-based innovative research efforts, both in vitro and in vivo, went into the development of the right combination with desirable benefits. After developing the product, the benefits were systematically evaluated under a wide range of conditions, such as controlled research conditions, semi-commercial trials (research pens set up inside commercial chicken houses), and under real commercial conditions. In addition to that, the mode of action of the product was further explored using advanced analytical tools. Biostrong™ Dual confers performance benefits to broilers across growth stages More than 15 independent trials were conducted under three different conditions, controlled research, semi-commercial, and commercial conditions to evaluate the performance benefits of the product. On average across the independent trials, birds fed with Biostrong™ Dual at 0.4kg/MT showed significant improvement in performance with respect to body weight (3.5% improvement), adjusted cumulative feed conversion ratio, cFCR (5 points reduction) and breast meat yield (1.53% increase). Interestingly, dietary inclusion of Biostrong™ Dual improved body weight (Figure 1) and cFCR (Figure 2) throughout the grow-out period with consistent benefits at different ages of the birds.
