Offered Papers Theme A: Efficient Production from Grassland
Description
In a dairy farming system based on pasture in Japan, maize grain is generally used as an energy source for milking cows, with almost all grain been imported. Potato-pulp is one of the agricultural by-products derived from the starch industry in the northern island of Japan. In our previous study (Aibibula et al., 2004), it was demonstrated that potato pulp could be preserved for a long time by ensiling without additives, and that the digestible energy value of potato pulp silage (13 MJ/kg DM) was almost the same as beet pulp. From these results, it is possible that some part of the maize grain fed to grazing cows could be substituted with potato pulp silage (PPS). The objective of this study was to compare PPS with rolled-maize as an energy source for cows grazing on temperate pasture.
