The recommendations considered the different breeds and hybrids of pigs raised in commercial farms, the different housing facilities and equipment used, as well as differences in management practices of various farms.  

Maximum allowances for some nutrients were provided to cover for the wide variations in composition quality and nutrient availability of various feed ingredients being used in different farms. Nutrient allowances were also provided to cover for the low feed intake of pigs raised under Philippine conditions. 

Tables 9 to 15 also present the various nutrient recommendations for different classes of swine from other countries. These are presented to serve as a guide for ration formulation, if one feels that the PHILSAN Nutrient Recommendations are not adaptable under certain conditions. 
PHILSAN did not make any recommendations for the various vitamin requirements due to very limited experience in this area.  

It is a common practice that the vitamin requirements of different classes of swine are met primarily through vitamin premixes, thus limiting the opportunity to properly evaluate the acceptable levels for different vitamins. Presented, instead, are samples of vitamin premixes that are used by some nutritionists.
