Good management of lowland sheep depends on strategic uses of resources during the management cycle and manipulation of body reserves. Critical periods are around mating, late pregnancy and early lactation. Good condition at mating is achieved by expanding the grazing area apportioned to the ewes in autumn. Thereafter, ewes are restricted to allow the resting of pasture for spring growth. A feeding plan for late pregnancy is given which takes account of body condition score and expected lambing date. The recommended concentrate ration contains a proportion of undegradable protein which is fed until grass growth can support lactation. Nutrition in later lactation is not limiting provided fertiliser nitrogen is applied regularly at a level related to stocking rate. By integration with other enterprises (cattle and crops), efficient use of resources is achieved.
低地绵羊的良好管理取决于管理周期中资源的战略利用以及身体储备的调控。关键时期是在配种、妊娠后期和泌乳早期。通过在秋季扩大分配给母羊的放牧面积来实现配种时的良好体况。此后，限制母羊活动，以便牧场休养生息，利于春季生长。给出了一份妊娠后期的饲养计划，该计划考虑了体况评分和预期产羔日期。推荐的精料日粮含有一定比例的不可降解蛋白质，一直喂到青草生长能够支持泌乳为止。如果按照与载畜率相关的水平定期施用氮肥，后期泌乳期的营养就不会受限。通过与其他企业（养牛和种植作物）相结合，实现了资源的高效利用。
