A positive relationship exists between dry matter intake and animal growth performance, gas flux, and CO2 production in growing steers.
CO2 and CH4 emissions explain about 48.1% and 40.9% of the observed dry matter intake respectively in backgrounding steers.
Analysis compared multiple equations for predicting dry matter intake, finding various levels of agreement and accuracy.
Results suggest that CO2 production may serve as a useful metric for estimating dry matter intake in steers on a forage-based diet.
