Extract

Increased lamb production during the 1980's stimulated interest in winter indoor finishing systems, traditionally all-concentrate. Recent research has been directed towards the supplementation of a silage-based ration as an option to reduce costs. The objective of this experiment is to compare the utilisation of metabolisable energy (ME) from silage and concentrate for carcass gain and to determine the effect of ME source on carcass quality.

Seventy-eight Blackface wether lambs (mean initial live weight 29.3 kg) were housed in late October and offered silage for two weeks prior to allocation to treatments.
