Abstract
The objective of this study was to calculate the unit price of an alternative feed ingredient for broiler chickens in consideration of the energy and nutritive contents in the feed ingredient by using a simple Excel worksheet. A corn-distiller's dried grains with solubles (corn-DDGS) was used as an alternative ingredient and corn and soybean meal as ingredients to be replaced. The net change of feed price was calculated based on the replacement values which were estimated in consideration of energy and nutrient concentration in feed ingredients used in the calculation, the price of feed ingredients and inclusion rate of the alternative ingredient. The nitrogen corrected apparent metabolizable energy(AMEn) and standardized ileal digestible AA including Lys, Met, Thr, and Trp, total Ca, and available P were employed as nutritive component to calculate the replacement values for individual feed ingredients. The equation for replacement was 1 ${\times}$ corn-DDGS + 0.0334 ${\times}$ soybean oil + 0.0182 ${\times}$ Limestone = 0.8893 ${\times}$ corn + 0.13 ${\times}$ soybean meal + 0.0004 ${\times}$ Lys + 0.0022 ${\times}$ Met + 0.0005 ${\times}$ Trp + 0.0028 ${\times}$ Thr + 0.0264 ${\times}$ dicalcium phosphate. The replacement price of corn-DDGS was calculated to be 270 won/kg when the inclusion rate was 15% and the energy and nutrient contents were considered in the calculation. In conclusion, the Excel-based ingredient price calculator may be useful to determine the economic value when an alternative feed ingredient is used in diets fed to broiler chickens.
