According to the Food and Drug Administration, water activity is a key parameter for determining the shelf-stability of foods. For feed, water activity ($a_w$) is a thermodynamic measure indicating the amount of unbound water available to support microbial growth and chemical reactions. It is distinct from total moisture content and is a far more precise predictor of feed safety, quality, and longevity.
