Description
Single linear correlation was established between in vitro dry matter digestibility (IVDMD) and contents of chemical entities as well as proportion of different tissues. Top and bottom leaves were sampled from Jaraguagrass, setariagrass and dwarf elephantgrass. Among the chemical entities, lignin showed better correlation with IVDMD. The proportion of sclerenchyma in the samples of stem and leaf lamina from the top layer and the parenchymall cells in the leaf sheath showed highly significant correlations with the IVDMS NDF content correlated positively with percentage of sclerenchyma, lignified vascular tissues and parenchyma bundle sheath, but negatively with percentage mesophyll and epidermis tissues. NDF showed good correlation with IVDMD, if associated with lignin.
