| Summary: | Studies in rumen activities and urea kinetics were
conducted to compare the digestion between cattle and buffaloes
fed fibrous diets.
On straw-based diets , buffaloes demonstrated higher rate
of rumen fermentation . The rumen pH of buffaloes ( 6.46+0.02)
was lower than cattle (6.78+0.02) , while the VFA
concentration was higher than that of cattle (98.0+2.2 versus
85.5+1.6 romo1/1 ) . The rumen ammonia was also found to be
higher in buffaloes (4.00+0.08mg N/100ml) than in cattle
(3.55+0.08mg N/ 100 ml ) . The rate of degradation of straw-1
was also faster in buffaloes (0.018 ± 0.003 h ) than in cattle-1
(0 . 010 + 0.004 h ) . A similar trend was observed when the
animals were fed guinea grass. Voluntary feed intake and water consumption were similar
for both species fed grass, but when fed fed straw, cattle
showed higher feed intake and lower water consumption than
buffaloes. There was no difference between cattle and
buffaloes in the rate of passage of small feed particles from
the rumen and rumen fluid volume based on liveweight was also
not significantly different between the two animal species.
However, the fluid outflow rate from the rumen was slower in
the buffaloes (1.06 +0.9 1/h) than in the cattle (1.55 ± 0. 01
1/h). |
