Extract

AFRC (1993) recommends a factor of 16 to calculate metabolisable energy (ME) concentration in a grass silage from its digestible organic matter (DOM) in total dry matter (DM) (DOMD), irrespective of variations in the concentrations of other nutrients (crude protein (CP), carbohydrate and lipid) in DOM. The objective of the present study was to examine the effect of silage quality on the relationship between ME concentration and DOMD in grass silages.
