The study of Forage Quality of Smirnovia iranica in Different phonological stages in sandy areas-case-study: Band-e-Rig-Kashan.

Smirnovia iranica, a native valuable woody species from fabaceae, is an adaptableplant of central sandy areas of iran. on other hand, this species could be markedlyconsidered from different view points of forage production, soil conservation andmedicinal applications.the current research was carried out in band-e-rig of kashan, iran to evaluatesmirnovia iranica properties including crude protein (c.p), ndf, adf, p, k, me anddmd in different phonological stages in order to find its forage quality for livestocknutrition. the result of chemicals analysis indicates that there is a significant differenceamong different phonological stages of s.iranica in terms of its properties. as the plantage is increased, c.p, me and dmd are decreased while ndf and adf are increased.this leads to reduction of s.iranica forage quality, since there is not significantdifference between flowering and growth stages in view point of their c.p, me, dmd,ndf and adf, also according to increase of p and k in flowering stage, it seems thatthis stage could be considered as favorable time for s.iranica utilization by livestock.
