This study was conducted to take up the following two subjects: (1) relationships between light interception by the forage canopy and its mean leaf area weighted by the light attenuation curve [MLA], and (2) relationships between feed ingestion by ruminants and mean retention time of feed in the rumen weighted by the feed disappearance curve [MRT], using simple models for forages and those for ruminants. The following results were suggested: (1) when the canopy leaf area index [L] was high the small coefficient of light extinction [Kf] enabled the canopy to have large MLA which could intercept more amount of light, whereas the saturation of light interception occurred in lower L when the canopy had large Kf, (2) daily feed intake [DFI] by ruminants increased with the increase in MRT 1 [=feed disappearance rate]. The present study using simple models suggested that MLA of the canopy of forages was like MRT-1 of feed in the rumen of ruminants as indices for the estimation of energy ingestion.
