Description
An investigation was made into the seasonal changes in the in vitro dry matter digestibility (IVDMD) of leaf blade (LB) and stem (ST) of individual tillers of napiergrass (Pennisetum purpuretum) grown at the high-altitude site (HA) and low-altitude site (LA) in Miyazaki prefecture, south-western Japan. Within a single sampling date, the variation in the IVDMD with tillers was small both for LB and ST. Negative logarithmic relationships held between the LB percentage and tiller dry weight and between the IVDMD and dry weight of LB and ST. The HA plants produced less dry matter as well as digestible dry matter than the LA plants in June. The HA plants had a greater number of tillers with smaller dry weight, higher LB percentage and higher IVDMD of LB and ST than LA plants.
