ARTICLE FEED & ADDITIVE MAGAZINE April 2024 59 The nutritional value of a food is defined by USDA as “the nutrients compounds of a food and their molecular relations”. Based on this definition, we can state that the nutritional matrix of a complete ration, or of its individual ingredients and additives, includes both their inherent nutritional content (i.e., protein, amino acids, fat, carbohydrates, etc.) and any additional indirect benefits it offers. These last ones gather a wide range of benefits such as the improvement of animal’s state of health, feed quality, availability, digestibility and absorption of nutrients. A classic example are enzymes, for which the nutritional value is derived from their action on other factors. The application of an appropriate and scientifically proven nutritional matrix remains fundamental for getting the maximum value from any feed formulated to match animal requirements, while optimizing its cost. IMPORTANCE OF APPLYING UPDATED FORMULATION MATRIX VALUE FOR METHIONINE SOURCES Can a methionine source bring extra values while applying its nutritional matrix values? The answer is yes, and in particular if we look to a source of OH-methionine in liquid form. In fact, this source of methionine, known as Hydroxy-Analogue of Methionine (OH-Me- “Applying the appropriate nutritional matrix for methionine sources will result in feed cost optimization, by optimizing complete feed Crude Protein & energy values (metabolizable or net energy). Due to its nutritional and molecular values and its relative cost, OH-Methionine is the best option while formulating optimal diets, especially when its validated matrix is completely applied.” THE IMPORTANCE OF APPLYING THE FULL MATRIX VALUE OF METHIONINE SOURCE AS A KEY TOOL TO OPTIMIZE FEED COSTS Nicola Tallarico Global Category Manager for Rhodimet® AT88 Adisseo Tahir Mahmood Scientific and Technical Solution Developer Adisseo
