Over the past decade, a lot of published feed composition tables both from local and international sources have been made available. If one takes a closer look at these information, however, variations in the nutrient levels of each ingredient are evident, making it more confusing on the part of the user to determine which of these figures are more accurate to use.  

To partially if not totally address this dilemma, the PHILSAN members reviewed the nutrient values for the different ingredients gathered from actual data available from reputable laboratories in the Philippines which are currently being used in feed formulations. The values presented in this chapter represent the average compiled data which we as a group unanimously agreed are good representations of the average actual nutrient composition of the feed ingredients in the countrv. 

The data on amino acid composition were derived from linear regression equations based on the actual average proximate analyses of the feed ingredients. It is important to always procure ingredients based on the standards set in Chapter I to stay within the range of these amino acid values Similarly, the metabolizable energy values for poultry and swine were based on regression equations utilizing the same actual average proximate composition of the ingredients (those in parenthesis) and published data.
