Crush margins in the hog industry are useful for monitoring the volatile feed (corn and soybean meal), weaner pig, and market pig prices. One model is the Gross Feed Margin Model (GFM), which uses corn, soybean, and wheat margins to determine return on feed purchases. The Hog Margin Tracker is a risk management tool and monitors both current and future markets. Either model can be useful on farm for assessing risks associated with feed and hog prices.
