Vast areas of oil palm plantations in North Sumatra are suitable for sheep production. Integrating sheep under oil palm plantation is being carried out at PTP VII Bah Jambi to develop improved systems of sheep husbandry in oil palm plantations. Daily management may be grazing, stall-feeding or a mixture of the two, depending on factors such as labor availability. Forage will always be the predominant feed resource for sheep production in oil palm plantations. At low stocking rates of one to three ewes per hectare, natural forages can support reasonable production levels in mature oil palm plantations without other feed resources. The productivities of sheep were encouraging such as ewe weight (kg) (n=649) 17.20 more or less 0.17; birth weight of lamb (first 1.87 more or less 0.08, second 1.54 more or less 0.14); weaning weight 8.52 more or less 0.01, ADG of lambs (g/d) 45.34 more or less 0.10, litter size 1.72 more or less 0.12, and lambing interval 222 more or less 0.06 days. The high potential for grazing under oil palm plantation illustrates the possibilities for expansion of integrated sheep production. Using anthelminthics regularly to control worm infestation and reduce mortality is one important management aspect in sheep rearing. The benefit cost ratio (BCR) of sheep raising was 1.52. This shows that the integration of sheep rearing with oil palm plantations can be profitable
