Effect of Corn Price on Profitability of Control Vs Phytase Enhanced Diet of Hogs AgEcon
Atreya, Ajita; Vitale, Jeffrey D.; Stoecker, Arthur L.; Carter, Scott D..
Economic Simulation model (SIMETAR) was used to investigate the effect of future corn price on profitability of control and phytase enhanced diet of hogs. The completed simulation model was used to estimate probability distribution for control vs lower excretion diet profitability under different corn prices. Data used was collected from recent field trials in Oklahoma that tested the effect of phytase enhanced diets on reducing phosphorus emission. The results showed that as the market price of corn increases control diet will be more profitable than phytase enhanced diet, given the cost of other remaining feed ingredient is constant for both the diets.

RESPONSIVENESS OF SWINE WASTE MANAGEMENT COSTS TO FEEDING LOW CRUDE PROTEIN DIETS AgEcon
Ancev, Tihomir; Carter, Scott D.; Stoecker, Arthur L..
Livestock waste management issues are of growing environmental concern in the United States and elsewhere. Lowering the quantity of nutrients excreted by pigs can ease associated environmental problems and at the same time can reduce waste management costs. Reduction in nutrient excretion can be achieved by feeding pigs with low crude protein diets. The paper develops a procedure for calculation of swine waste management costs as function of four dietary regimes. Feeding low crude protein diets significantly reduced amount of nitrogen excreted by pigs. As a result, reduction in waste management costs may be achieved, especially when the pig farm does not have enough land to apply all the manure it generates.
