1Respondents who added the nutrient to the diet from the 4,245,700 sows surveyed. Reported values are on a complete-feed basis.
2Sum of the products of the inclusion level multiplied by the size of the production (# of sows), divided by the total number of sows from the participants that provided added levels for that nutrient.
3 NRC (2012) does not provide a recommendation level of the nutrient.
