Nutrient Distributions
Given the number of observations for each nutrient value, these
distributions indicate some outliers to be identified. However the
frequency outside the distribution curve appears to be relatively
low.
Notable outliers/outside normal distribution
Nitrogen : May (Plots 4, 6, 50, 51) | July (Plots 6, 50, 95)
Carbon: May (Plots 4, 6, 18, 50) | July (Plots 6, 40, 42, 50)
Nitrate: May (Plot 72) | July (Plots 16, 29, 71, 74, 81,)

Forage Quality Distributions
Moisture Content (few outliers observed)
Distributions seem typical of early vs late seasons
Dry Matter
Protein
As Received vs Dry Weight comparison, No significant differences in
distribution patterns
Notable outliers (May: Plots 903, 904) (June Plot 903)
Fiber (acid detergent)
May and June has a somewhat uniform distribution/no outliers to
note
September outlier Plot 918
Total Digestible Nutrients
May and June has a somewhat uniform distribution/no outliers to
note
September outlier Plot 918
Net Energy Distributions
Lactation ~ September outlier Plot 918
Maintenance ~ September Plot 918 outlier
Gain ~ September Plot 918 outlier
Forage Quality measurements (mean+-SE)
By burn treatment (“Burned”, “Unburned”), ecosites, and month.
Suspect that some of the distributions (ex. May/Unburned) and the
overall sample size could be affecting this, given the amount of
variables used
