There is increasing interest in the addition of dry feed materials to grass at ensiling, primarily as a means of reducing effluent production although other benefits claimed include improvements in silage fermentation and animal performance. The objective of the present study was to examine the possible use of molassed sugar beet pulp fed either separately or ensiled with grass at the time of silage making on ewe and lamb performance, and with or without protein supplementation.Grass from a primary growth of perennial ryegrass with dry matter, water soluble carbohydrate and crude protein contents of 13.2%, 24 g/kg and 106 g/kg DM respectively was mowed on June 2nd and was picked up using a precision chop harvester on the 4th and 5th of June. The weather during this period was extremely unfavourable for good silage making. There were 7.5, 1.5 and 2.8 mm of rainfall on the 3rd, 4th and 5th of June. The temperatures (0 C) on these days were: 2nd June - 12.9: 3rd -10.6: 4th - 10.7. There was no bright sunshine hours on either the 3rd or 5th of June and only 2.1 hours on June 4th. Two treatments were imposed (i) formic acid (2.5 litres/t) applied in the field via the forage harvester (GS) (ii) molassed sugar beet pulp (MSBP)(50 kg/t) applied by hand in the silo on top of each load of grass(GSP).The two silos were filled .consolidated and sealed within 24 hours.
