Managing natural variations

Variation of nutritional values in feed raw materials such as corn and soybean meal can result in suboptimal animal growth and cost efficiency when they ?deviate from reference values. Samples from South America were surveyed the energy and digestible amino acid content, and compared with reference tables. The variations can be controlled by precise nutrition evaluation using NIR, which is a good option to optimise feed formulation. By Marjolaine Le Meur-Boitier, marketing manager Rovabio, Adis
