In animal feed quality management, sample preparation often can be improved.
Feed manufacturers require grain and feed analysis and testing to comply with regulations and to abide by their voluntary testing programs. Research and development departments use testing results to identify the best nutritional criteria and requirements, to study the relationships between nutritional requirements and production efficiency, but also to assess new raw materials. In formulation, nutritionists use them to learn about raw material variability and to control quality when they physically enter the factory. Analysis is also quite useful at the process level and, of course, more widely to control biosecurity.
