Dosage for compound feed

The analysis of compound feed aims to determine the overall nutritional composition of products intended for animal or human consumption. This analysis provides a comprehensive overview of the main constituents: proteins, lipids, carbohydrates, fiber, and minerals. It allows for verification of formula compliance, optimization of formulations, and ensures accurate and legally compliant nutritional labeling.

Analytical methods

The assay relies on a set of complementary methods allowing each parameter to be evaluated precisely:

• Kjeldahl method for the determination of total nitrogen and the quantification of crude proteins ;
• Soxhlet method for the extraction and quantification of total lipids ;
• Ion exchange chromatography or HPLC for the measurement of carbohydrates (simple and complex sugars);
• Gravimetry for fiber or ash content;
• Near-infrared spectroscopy (NIRS) for rapid and non-destructive evaluation of nutritional constituents.

These techniques can be combined depending on the analytical needs and the nature of the matrix. For targeted analyses, also consult our catalog for protein (Kjeldahl method) , total lipid , or dietary fiber analysis

Industrial applications

This analysis is essential in several areas:

• Animal nutrition : control of the formulation of compound feeds to guarantee a balanced intake of nutrients according to the needs of each species (ruminants, poultry, pigs, fish).
• Agri-food : verification of nutritional values ​​displayed on the labels of processed products.
• R&D and formulation : development of new recipes or fortified foods according to the desired nutritional profiles.
• Quality control : batch monitoring, non-conformity detection and evaluation of formulation stability.

This panel of analyses provides an essential basis for controlling inputs, optimizing production costs and complying with European regulatory requirements.

Analytical interest and complementarity

The dosage for compound feeds can be supplemented by other tests to obtain a complete nutritional profile:

• Amino acid analysis to assess protein quality;
• Mineral analysis (ICP-OES, AAS) to determine the content of macro and trace elements;
• NIRS analysis of forages and raw materials for rapid on-the-ground control;
• Determination of total and resistant starch for the energy evaluation of formulations.

These additional analyses allow for fine-tuning of formulations, improving digestibility and guaranteeing the nutritional consistency of finished products.
