Vegetation covers of arid and desert areas are mainly halophyte plants. These plants are impotent in terms of feed resource for domestic animal such as sheep, goat and camel in the mentioned areas. An experiment was conducted to determine the nutritive value of 5 halophyte plants including: Gamanthus gamocarpus (G.ga), Petrosimonia glauca (P.gl), Salsola crassa(C.cr), Halotis occulta (H.oc) and Halocaris sulphurea (H.su). The chemical composition, digestibility [the two stage (in-vitro) technique], dry matter consumption [ad-libitum], animal preference and palatability ratio [cafeteria fashion] were measured by sheep. The results indicated that (H.su), (H.oc) and (P.gl) have higher digestibility in dry material, in organic matter and in organic matter of dry material than (G.ga) and (S.cr), (P0/05). The dry matter consumption (H.sa) and (S.cr) were higher than other plants (P0/05). In this experiment, animal preferred (G.ga) and (S.cr) higher than other plants, while the lowest preference was be long to (H.oc).
