[Nyctohemeral variations in the ammonia concentration in rumen fluid, in dairy cows during the peripartum period].
Automated and continuous recording of ammonia concentration in rumen liquor (Godeau et al., 1986) was performed on four cows around their first calving. Results suggest an insufficient concentration in early lactation.
