Rumen biopsy in rumen-cannulated dairy cows

Popis výsledku v původním jazyce

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
