Kansas Agricultural Experiment Station Research Reports

Research has shown that carcass yield is reduced when feeding distillers dried grains with solubles (DDGS) or other high fiber ingredients. Considering the financial implications of changing carcass yield, the objective of this project was to develop regression equations to accurately estimate carcass yield from dietary NDF withdrawal strategies. Data from 8 trials originating from 5 journal articles, 2 theses, and 1 technical memo were used to develop a regression equation to predict carcass yield. The regression analysis showed that number of days in the withdrawal period (WP), NDF level in the dietary phase prior to the final phase (NDF1 ...

Kansas Agricultural Experiment Station Research Reports

Feed accounts for a significant portion of swine production cost, with dietary energy alone representing more than half of the total cost. Considering the financial implications of determining the energy content of the diet, the objective of this research project was to develop a tool to accurately estimate the dietary NE content that yields maximum profitability for growing-finishing pigs. A Microsoft Excel®-based model was developed to contrast dietary NE defined by the user with recommended concentrations that are intended to maximize profitability in user defined production and economic scenarios. To calculate pig performance, the model uses prediction equations for ...
