Two different-type equations of relative growth rate [RGR] for both forages and ruminants were taken up in the present study. Four equations of RGR each were composed of three or more components, and some features of them were summarized as follows: (1) forage RGR related to production analysis, (2) forage RGR related to utilization analysis, (3) ruminant RGR related to metabolic body size, and (4) ruminant RGR related to feed digestibility. Three of them, namely equations (2), (3) and (4) were discussed with data. Then, four equations were derived, as special cases, from a hypothetic equation for RGR suggested in the present study. This hypothetic equation was reduced to that suggested previously (Shimojo et al., 1998a, b) from which RGR equation with two components for forages and that for ruminants had been derived as special cases.
