ABSTRACT

Cannulated Holstein Friesian crossbred milking cows (Two) were maintained on control diet
(T1) and another (T2) on experimental diet for six weeks. The rumen fluid was collected at 0, 2, 4, 6
and 8 hours of post feeding from seventh week for analyzing pH and TVFA (Total volatile fatty acids
) concentration. The mean pH and TVFA levels of T1 and T2 groups were 6.91±0.05 and 6.52±0.07;
79.77±2.10 and 90.67±3.35 mMol/ l, respectively. The ruminal pH values were significantly lower
(po05) and the TVFAs concentration were significantly (p
