Extract

In a previous study at this Institute, significant increases in total dry matter intake were obtained with first lactation animals offered grass silage and concentrates as a complete diet rather than in separate feeds. However, the increased DM intake associated with complete diet feeding was not reflected in improved animal performance. Similar results have also been reported by Phipps, Bines, Fulford and Weller (1984) and Cassel, Merrill, Milligan and Guest (1984).

The aim of this experiment was to investigate the effect on animal performance of offering two types of concentrate in addition to grass silage, with concentrates offered either as a complete diet or in three feeds per day.
