The aim of this research was to investigate the nutrition value of Cressa Cretica in different stages of phonological. The samples were dried in shadow, then milled and their chemical composition were measured in laboratory. Degradability of dry matter (in situ), digestibility of organic matter (OMD) and metabolizable energy (ME) were measured by using gas production (in vitro) and digestibility of dry matter (DM), crud protein (CP), ether extract (EE), natural detergent fiber (NDF) and acid detergent fiber (ADF) were measured by using (in vivo) method. The results showed that between in growth stages significant difference were observed, except in DM, EE and calcium (P<0.05). Quantity of OMD in three phonological stages of growth, flowering and seeding was 56.34, 58.04 and 58.44 percent receptively. Quantity of ME was 8.4, 8.71 and 8.69 MG/kg receptively. Significant difference (P<0.05) was observed in degradability and effective degradability in different phonological stages. The digestibility mean of DM, CP, EE, ADF, NDF in three phonological stages of growth, Flowering and seeding were 53.73, 50.71, 49.16 (DM), 83.91, 52.95, 51.9 (CP), 61.71, 72.7, 69.71(EE), 26.67, 20.18, 38.17(ADF) and 35.78, 30.85, 46.85 (NDF) percent, receptively. The results showed that Cressa Cretica has more performance when fed to animal at seeding stages.
