Abstract

Experiments were conducted to determine the effect of time intervals between collecting and use of cattle faeces as a source of micro-organisms in in vitro digestibility assays of forages. The results suggested that temperature conservation capacity by faeces depended on the size of the sample. There was no significant difference(p>0.05) between the first (T1 or 08:30 h) and second using time (T2 or 10:30 h). In vitro organic matter digestibility was significantly lower when faeces was used 5 h (T3 or 13:30 h) after collection. However, the organic matter digestibility determined at the second using time (T2) and third using time (T3) were highly correlated ($R^2=0.99$) with the first using time. It was concluded that faeces can be used as a source of microorganisms for in vitro digestibility assays of forages even 5 h after being voided.
