# Return to corn-soy diets

> Ethanol plants are idling because of low oil prices during the COVID-19 pandemic, which is cutting DDGS availability and forcing pork producers to pull DDGS from swine diets. Kansas State nutritionist Bob Goodband advises returning to corn-soy diets and watching amino acid ratios and digestible phosphorus.

## Why it matters

Losing DDGS shifts swine feed demand back toward corn and soybean meal, which supports those ingredients while weakening DDGS prices. Higher amino acid and phosphate use adds cost pressure on rations.
