Abstract

In this study another-type hypothetic equation with three parameters, which was slightly different in the form from the previous equation (Shimojo et al., 1998b), was suggested to the growth analysis of both forages and ruminants. From the present hypothetic equation, absolute growth rate [AGR] and relative growth rate [RGR] of forages and those of ruminants were derived as special cases. In addition, when a certain substitution was made for parameters, AGR and RGR equations each were shown to be composed of daily forage intake [DFI] per animal or per unit body weight, net assimilation rate [NAR] per plant, and the term suggesting a sort of relationship between ruminant DFI and forage NAR. This relationship was suggested by adjusting growth period and yield of the forage to be equal to its feeding period and cumulative intake in the ruminant, respectively.
