When pasture digestibility falls to less than 50%, energy becomes limiting for maintenance for all classes of sheep, and feeding protein will not aid further utilisation of dry pasture.Providing high rates of feed (more than 100 grams per head per day) will lead to substitution, where the sheep choose the supplementary feed over pasture, leading to reduced pasture utilisation.digestibility needs to be at least 50 to 55%.the amount of dry pasture should be nonlimiting, at least of 1500 kilograms of dry matter per hectare (kgDM/ha) of feed on offer (FOO).Improve utilisation of dry pasture or stubble – which is low in protein and high in fibre – by supplementary feeding with 20–50 grams per head per day of a supplement high in protein, such as lupins. See the sheep feed value guide for more information on nutrient values of different feedstuffs. If you are growing sheep for meat production, seek professional advice regarding ration quality and the energy-to-protein ratios in the supplement. It is especially important to prevent excessive liveweight loss during the dry pasture phase in weaners and pregnant ewes. Supplementary feeding aims to meet the nutritional requirements of different classes of sheep.

In this case, the 'supplementary' feed becomes the full ration. Where pasture or stubble ground cover is less than 50%, where wind erosion is likely, we recommend feeding in stable confined areas or in feedlots. In Western Australia later in summer and autumn, supplementary feeding often becomes substitution feeding where sheep choose to eat the added feed rather than that available in the paddock.

Supplementary feeding is the supply of additional feed (usually grain, hay or silage) to sheep grazing a pasture or stubble that is lacking in energy or protein.
