[The composition of rumen fluid of cattle collected from fistulas using ultrasound].
Concentrations of rumen fluid characteristics were compared between rumen fluid which was taken by standardized conditions via stomach tube and via rumen fistula respectively depending on time after feeding (2.5 or 9 hours ppr.). The results were as follows: Differences (%) of the characteristics of rumen fluid taken via stomach tube to that by rumen fistula: [table: see text] Other investigations showed that the admixture of saliva to rumen fluid resulted in a degradation of the concentrations especially of VFA. The pH was not appreciable changed. The consequences for veterinary practitioners are discussed.
