Effects of feed intake and lipid content of the diet on numbers of free bacteria and those adhering to particles of rumen contents in dairy cows



Effects of feed intake and lipid content of the diet on numbers of free bacteria and those adhering to particles of rumen contents in dairy cows



Reproduction, Nutrition, Developpement 28(1): 139-140



Attached large (LPAB) and small particle (SPAB)-associated bacteria amounted to 15.5 and 53.0% of DM particles, respectively, in dairy cows fed on control or high-fat diets (P <0.01). Liquid-associated bacteria (LAB), which amounted to 3 g/litre decreased from 4 to 6 h after the morning meal with the control (-37%, P <0.05) and the high-fat (-19%) diets. In total rumen content, bacteria LPAB and SPAB-attached particles accounted for 69 and 17% of total bacteria, respectively.
