There was a tendency for cows fed SHSL to maintain
higher ruminal NH3 concentrations, but there were
no other differences due to SHSL inclusion for the
ruminal parameters measured. The lowered ruminal
pH and elevated concentrations of VFA and lactate
suggest the model used to induce SARA was successful.
The partial replacement of alfalfa hay, corn silage,
corn, and SBM by SHSL did not affect the observed
responses to SARA challenges.
