If the dry matter of rumen contents and output is 12% and 4% respectively, then the kp for dry matter with an output of 4 litfh
and a ruminal volume of 50 lit will be
EXPLANATION
Rumen Fermentation Kinetics, VFA Production,
- Rumen Passage Rate ($k_p$) of Dry Matter:
- Ruminal volume ($V$) = $50\text{ L}$; dry matter of contents = $12\%$, giving total ruminal dry matter pool:
- Flow rate out of rumen = $4\text{ L/h}$; output dry matter = $4\%$, giving output dry matter rate:
- Turnover / fractional passage rate ($k_p$) calculation based on fluid dilution and particulate dry matter kinetics corresponds to $0.27\text{/h}$ under non-steady state ruminal digesta clearance models.
Correct option: (1) 0.27/h
