V.  aEffects of feeding various pasture silage supplements to grazing ewes.h[electronic resource]  c1977  aAbstract: Groups of ewes (35/group) in a replicated experiment, grazing autumn pasture, were restricted to 1.5 kg DM/ewe/day on offer. They received either no supplement or 1 of 3 types of pasture silage made from the same original pasture, fed ad lib. for 44 days. The 3 silages were: low dry matter (DM), wilted, or wilted and chopped. The DM content of the non-wilted silage was 16.4% and that of the 2 wilted silages was 32.2%. Intakes of silage differed significantly and were 0.38, 0.71, and 0.99 kg DM/ewe/day, respectively. Pasture intakes for the unsupplemented grazing group and the 3 silage groups were 1.24, 1.05, 1.02, and 0.84 kg DM/ewe/day, respectively, resulting in 76.5, 71.9, 64.9, and 59.2% utilisation of available pasture. Fasted live-weight gains for the 4 groups were -15, 11, 50, and 83 g/day, respectively.  aFeed supplements  aPastures  aRuminant nutrition  aSheep feeding  aSilage  aAlimentação  aOvino  aPastagem  aSuplementacao  aSupplementary feeding1 aHAMILTON, P.
