How phytogenics add value for feed producers and integrations

hytogenic feed additives are a mixture of plant-derived material containing active ingredients that can be considered as part of the plant secondary metabolites. These secondary metabolites are, in general, produced by plants in respect to three main mode of actions: firstly, they play an important role for the protection of the plant from both abiotic and biotic stress; secondly, they are needed by the plant to attract different pollinators and, thirdly, they play an important role for the defense of the plant itself. In fact, some of these metabolites can help against herbivores (as, for example, repellants or because they are toxic to the organisms), but also against different microbes (by inhibiting the growth of the microbes or reducing their virulence); and, they are also important for the plant to compete against other plants (by inhibiting germination of adjacent plants or inhibiting the growth of seedlings and so on).
The role of phytogenics in animal nutrition
Phytogenics are known to have a range of biologically active properties beneficial in modern livestock production, including antioxidative, anti-inflammatory, anti-microbial and nutrient 50 50 | |August August2020 2020--Milling Millingand andGrain Grain
absorption-enhancing effects. According to results of the Biomin Phytogenic Feed Additives Survey, we have a clear picture of the reasons that nutritionists, growers, business owners, veterinarians and consultants use or recommend the application of phytogenic feed additives in animal diets. Top reasons for applying phytogenic feed additives: 1. Digestibility enhancement 2. Antimicrobial effects 3. AGP replacement strategy 4. Growth promotion 5. Anti-inflammatory effects 6. Good past experience 7. Better feed conversion ratio 8. Higher feed intake (Source: Biomin Phytogenic Feed Additives Survey)
Commodity vs innovative value proposition
These secondary metabolites can be very versatile in their mode of action and their characteristics can also help to improve and support animal production. The raw materials used for phytogenic feed additives can be bought as commodities. However, the level of active substances in these commodities naturally varies, so it’s important to have strict purchasing and quality control guidelines
