Pressman et al 2025 - JDS - Comparing gas spot sampling schemes in cattle - Supplemental Materials

Supplemental materials for "Comparison of strategies for spot sampling enteric methane and hydrogen emissions to evaluate methane-reducing feed additives in dairy and beef cattle" (Pressman et al., 2025, Journal of Dairy Science; DOI: 10.3168/jds.2025-26470). These materials contain one supplemental data table and five supplemental figures.

Contents:
Table S1: Raw average emissions and total DMI data and number of animals included in analysis by experimental week in the Beef Experiment.
Figure S1: Pairwise contrasts by sampling strategy on estimated marginal means of CH4 yield within each treatment group-sampling strategy combination in the Dairy Experiment.
Figure S2. Pairwise contrasts by sampling strategy on estimated marginal means of total DMI within each treatment group-sampling strategy combination in the Dairy Experiment.
Figure S3. Pairwise contrasts by sampling strategy on estimated marginal means of CO2 production within each treatment group-sampling strategy combination in the Dairy Experiment.
Figure S4. Pairwise contrasts by sampling strategy on estimated marginal means of hours between last feeding and GF visits within each treatment group-sampling strategy combination in the Dairy Experiment.
Figure S5: Pairwise contrasts by treatment group on estimated marginal mean of voluntary daily visits under all voluntary sampling strategies in the Dairy Experiment.
