This study was planned to relate two different-type equations analyzing the increase in dry matter indigestibility (IDMI) in the growth of forages. The following equation showed the relationship between two equations, namely, the the left-hand side equation by Masuda (1985) and the right-hand side equation which was a changed form of the original equation by Shimojo et al. (1995). I1/W1 · [exp {(RGRi - RGRw) · (t2 - t1)} - 1] = (1 - W1/W2) · (SFR/RGRw · D/W - I1/W1), where W = forage dry weight (W1 ≠ W2), I = dry weight of indigestible materials, D = dry weight of digestible materials (D1 ≠ D2), RGRw = mean relative growth rate of forage, RGRi = mean relative growth rate of I, (1 - W1/W2) = forage growth index [FG index], SFR = mean specific formation rate of I per unit D, D/W = the ratio of D to W [D ratio], {(SFR/RGRw) · (D/W) -I1/W1} = a changed form of DMP index (DMP index: index for dry matter partition into I). The following results were obtained: RGRi was found to be related to SFR from their positions in the equation, and this might support the suggestion by Masuda (1985) about the close relation of RGRi to SFR. SFR might substantially relate the equation by Masuda (1985) and the equation by Shimojo et al. (1995). It was suggested that there was a close relationship between two different-type equations analyzing the increase in dry matter indigestibility with growth of forages.
