SED standard error of difference, na not available as non parametric test was used.
Faecal, urinary and blood parameters from cows fed regular TMR diet (control) and TMR + wheat-barley pellets (SARA). Estimates are given as least squares means from the repeated measurements model (for sodium, glucose and lactate arithmetic mean and P-values from Kruskall Wallis test are given).
