Swine Manure Production and Nutrient Content

Abstract

Knowledge of the amount of manure and plant nutrients produced on a swine farm is the first step in the proper operation of a swine manure handling, treatment, and utilization system. The nutrient and volatile solids content of swine manure will vary with the digestibility of the ration, animal age, amount of feed wasted, the amount of water wasted, and the amount of water used to remove manure from the building. The data provided in this chapter is to be used for general planning purposes. South Carolina regulations (Standards for the Permitting of Agricultural Animal Facilities: R.61-43) require swine producers to have manure samples analyzed annually to establish land application rates.
