SAVGUN  develops a optimum relationship between feed                  quality and animal performance  which  is  important and                 encompasses not only the quantitative amounts of all feed                  components but also the  digestibility and metabolism of                           those  components. Thus, the challenge for animal                         nutritionists and  others involved in feed production is to                   consistently monitor all aspects of feed production system                  being used and    measure those variables that are good                      indicators of quality control.
