In experiment 1, rumen fluid samples were obtained from dorsal, midpoint, and ventral regions of the rumen of rumenfistulated dairy cows at hourly intervals for 24 h. Dorsal, midpoint, and ventral rumen fluid samples contained 16.1, 14.2, and 12.1 mg/100 ml of ammonia nitrogen. Time after feeding resulted in differences in the concentration of ammonia in rumen fluid with the greatest concentration 30 to 90 min postfeeding. The concentration of ammonia nitrogen was greater for cows fed a high… CONTINUE READING
