ASAS Growth and Development I

analyzed as a Latin-square design using PROC MIXED in SAS. Forage quality was analyzed as a completely random design using PROC GLM in SAS. The BMR varieties were lower (P < 0.01) in ADF and NDF at all harvest dates, while N concentrations were not affected (P > 0.41) by variety. The A fraction of DM and NDF was higher (P < 0.01) and the C fraction of DM, NDF, and ADF was lower (P < 0.01) for BMR than non-BMR. The B fraction of DM was not affected (P = 0.15) by variety, while the B fraction of ADF was higher (P < 0.01) in BMR than non-BMR. The B fraction of NDF was not different (P = 0.28) on d 34, but was higher (P < 0.01) on d 48 and 63 for BMR than non-BMR. The A fraction of DM and ADF was higher (P < 0.01) and B fraction of ADF was lower (P < 0.01) for MS505 DS compared to Nutri + Plus BMR. Rates of DM and NDF dissappearance were higher for BMR than non-BMR for all harvest dates (P < 0.01). Dissappearance of ADF was faster (P < 0.01) with BMR than non-BMR on d 48 and 63. Effective degradability of DM, NDF, and ADF was higher (P < 0.02) for BMR than non-BMR at all harvest dates.
