Abstract: Recently, the dependence of grazing practices on forge supplementation, water hauling, hired labor and other livestock production factors have been substantially increased. Since, livestock grazing practices in Saudi Arabia has changed from the traditional pastoral system to a more sophisticated, business oriented practice, it was essential to study livestock production cost function on rangelands to determine the optimum herd size. The study is based on survey research of livestock production on rangelands (sheep, goats and camels) in Rumah area. The cubic functional form for the total cost function is applied on two classes of grazers (only sheep and goats, and sheep, goats and camels) to determine the optimum economical hard size of livestock production. The relation between livestock production and the herd size is also considered. Results indicated that herds constituted of sheep, goats and camels are smaller than those of only sheep and goats for the same livestock production level. The optimum economical herd size of the first class (only sheep and goats) was 480. However, it was undetermined for the second class due to the dominance of the linear relationship on the total cost function. Increasing the livestock production by one animal unit was associated with an increase in herd size by 1.07 animal unit for the second class, where it was 2.55 animal for herds constituted of only sheep and goats
