Silage density is negatively correlated with dry matter losses in storage and has been used as an Extension evaluation tool to assess ensiling management practices on farms. We compared three methods for estimating silage density on 18 farms. Core sampling is the standard method, while the calculator and feed-out methods are new alternative methods. Core sampling results were highly correlated with the calculator method but not with the feed-out method. Core sampling and the calculator method are recommended tools for estimating storage dry matter losses and evaluating alternative ensiling management practices by Extension faculty, producers, and other users
