DYNAMIC DECISION MAKING TOOLS

Decision making in a swine production system requires an in depth understanding of all key drivers of the production chain. Thus, it becomes essential for nutritionists to have available a set of tools that can help them navigate through these highly dynamic scenarios and make informed decisions.

PIC ADJUSTED CALORIC EFFICIENCY CALCULATOR BY SIRELINE
There are multiple factors that influence feed efficiency of wean to finish pigs. Three major factors affecting feed efficiency are entry and final body weight, dietary energy, and sireline. Most production systems adjust feed efficiency for final weight in the nursery phase and entry and final weight in the finishing phase in order to have a meaningful comparison between close outs. A recent adjustment that has been added in some production systems is for dietary energy (Gaines et al., 2012). A 1% change in net energy of the diet is expected to change feed efficiency by 1% (Euken, 2012). Dietary energy changes through time because of changing ingredient prices. Therefore, adjusting for dietary energy to compare between close outs and to evaluate performance changes overtime becomes important. Finally, different sirelines have different growth rate and feed efficiency. Thus, using sireline-specific coefficients to adjust for entry and final weights is now possible.

ECONOMIC MODEL FOR OPTIMUM TRYPTOPHAN:LYSINE RATIO FOR NURSERY AND FINISHING PIGS
This tool, developed by Kansas State University and Ajinomoto Heartland, calculates the most economical SID tryptophan (Trp) to lysine (Lys) ratio by taking into account information specific to your production system and market price. The underlying models were developed using PIC genetics under commercial conditions. The tool also takes into account if the production system is marketing pigs on a fixed time versus a fixed weight basis and the impact of different SID Trp:Lys to maximize profitability.

OPTIMUM CORN DDGS CALCULATOR
This calculator developed by Kansas State University attempts to consider economic return per pig from change in diet cost, feed efficiency, and growth rate. It does not account for any economic impact on yield or iodine value. Download this tool at http://www.asi.k-state.edu/research-and-extension/swine/calculators.html
