For determining the quality of cattle feed, mixing process is one of the most important operations in cattle feed manufacturing plant. Preparing premix of micronutrients with a suitable carrier is a common method used to ensure proper distribution of micronutrients in final feed. Uniform mixing is a key to quality feed production. Uniform mixing is not only important for achieving optimal animal performance, but also helps to reduce animal exposure to potentially harmful compounds by diluting them to approved and safe concentrations. The feed industry has historically used the percent coefficient of variation (CV) to evaluate the uniformity of mixing. The most common marker used for calculating CV% is common salt, which is generally added @ 1.0% in cattle feed production. Premix and feed mix should have maximum 5.0 and 10.0% CV, respectively for ensuring uniform mixing.
