Cow faeces in in vitro digestibility assays of forages
S. Akhter, M. M. Hossain
The present study investigated the use of cow faeces as a source of micro-organisms instead of sheep rumen liquor in in vitro digestibility assays of forages. Initially 40 forage samples comprising ryegrass, wheat, maize and barley were screened to select a wide range of digestibility (327-794 g/kg) of forages. Finally 8 forage samples were assessed using rumen liquor as well as faecal liquor. The absolute organic matter digestibility (OMD) values using faecal liquor were lower than those with rumen liquor. However, the relationship between OMD using rumen liquor and faecal liquor was highly significant (p < 0.001). The R2 value exceed 0.90. The results suggest that micro-organisms from faecal liquor are capable of digesting forage samples.
