ISSUE FOCUS 30 FEED & ADDITIVE MAGAZINE April 2025 RAW MATERIAL CHARACTERISTICS & VARIABILITY CONTROL The raw materials used in animal nutrition are numerous, diverse and complementary. Studying their intrinsic characteristics is fundamental to understanding the nutritional potential of each one, as well as identifying the anti-nutritional components that can limit their use in feed. Strategies adapted to the nature of the anti-nutritional factors, such as plant selection, the application of heat treatment or the incorporation of enzymes into the feed, are known levers for maximising the animal's use of the nutritive compounds in the raw materials. Controlling the quality of raw materials through regular chemical or NIR analyses is another essential element in guaranteeing a stable, high-performance feed. It enables the measurement and consideration of the raw materials' actual nutrient content, which can vary to a greater or lesser extent from one supply to another. For example, the simple fact of taking into account a one-point drop in moisture in the maize formulation matrix results in a saving of around €1/t of feed. This is due to the higher energy value provided by the drier maize. This detailed knowledge of raw materials and the control of their variability through the use of evolving raw material matrices when formulating feed is the first lever for optimising feed costs. Optimising feed costs requires a multi-factorial approach that goes far beyond simply managing the optimisation of feed recipes using formulation software. It requires precise knowledge of the raw materials used, considerable expertise in feed digestibility and an appropriate choice of nutritional strategies to be implemented according to the zootechnical objectives set.
