| Description
| - The current contribution describes rumen biopsy as a method to evaluate rumen health and development of rumen papillae in dairy cows. Rumen biopsies were performed in 12 pregnant rumen-cannulated Holstein-Friesian cows in their first lactation in week -8, -6 and -2 before the expected date of calving and at day 3, 7, 14, 28 and 56 after calving. First, samples of rumen fluid were taken to measure pH and volatile fatty acid content. Then a full rumen evacuation was performed, rumen content was weighed and samples of rumen papillae were taken with a sharp biopsy forceps at four locations. Inspected locations were 1) in the dorsal rumen sac, right rumen wall, directly across the cannula opening (A); 2) in the atrium ruminis, front right rumen wall (B); 3) in the caudodorsal blind sac (C); and 4) in the caudoventral blind sac (D). Based on the dimension (length and width) of rumen papillae the rumen scores at each location were determined. The current contribution presents results based on one cow as an example. The average pH at week -8 to -2 relative to calving was 6.99. After calving (from day 3 to 56) the average pH decreased to 6.39. There was a tendency for increasing amount of fresh feed in the rumen from one week postpartum, whereas body weight of the cow decreased after calving. The average rumen score was highest in regions C and D. In contrast, rumen papillae density and dimensions were lowest in the region B.
