Supplementary material to "Meta-analysis of lipid- and starch-based dietary interventions to mitigate enteric methane emissions, fecal organic matter, fecal and urinary nitrogen excretion in dairy cows"

These two supplementary files contain Tables S1–S6 and Figures S1–S16 accompanying the manuscript entitled “Meta-analysis of lipid- and starch-based dietary interventions to mitigate enteric methane emissions, fecal organic matter, fecal and urinary nitrogen excretion in dairy cows” The documents provide detailed statistical summaries of the dataset used in this meta-analysis, including the pool of univariate models, illustrative figures, and additional references related to the main text. Specifically, the supplementary materials present data on feed intake and diet composition, nutrient digestibility, enteric methane emissions, fecal organic matter and nitrogen outputs, as well as urinary nitrogen excretion in dairy cows.
