DDGS Calculator
This calculator is designed to help swine producers determine the inclusion rate for DDGS in the diets of nursery pigs, finishing pigs, sow, and gestating sows.
Distillers dried grains with soluble (DDGS) is produced from the fuel ethanol industry and is available for inclusion in diets fed to swine. During recent years, several research projects have been completed to investigate the feeding value of DDGS. Crude nutrient concentrations, energy and nutrient digestibility values, and effects of including DDGS in diets fed to different categories of swine have been investigated.
Diets formulated to contain DDGS should be formulated on the basis of digestible amino acids and digestible phosphorus. In general, 10% DDGS can replace approximately 4.25% soybean meal and 5.70% corn, if 0.10% crystalline lysine is included in the diet. DDGS can be included in diets fed to nursery pigs, growing finishing pigs, and sows in amounts of 20% and in diets for gestating sows at 40%. At these inclusion rates, excellent performance of pigs has been reported provided that diets were formulated on the basis of digestible amino acids. Greater inclusion rates are possible, but may not always maximize pig performance.
Microsoft Excel or Excel Viewer (a free download) is required to utilize the calculator. If you require the data from the calculator in an alternative format, please contact Roger Brown at RB-Brown1@wiu.edu.
