A study was conducted to investigate the effect of supplementation of Atriplex halimus with dried powders of aromatic plants on its in vitro dry matter digestibility. 400± 5 mg of dried Atriplex samples were incubated for 12 or 24 hours with buffered rumen liquor from sheep and supplemented with 100 mg of either Salvia officinalis or Rosmarinus officinalis. The result of this study demonstrated that the in vitro dry matter digestibility of A. halimus was 48.4% and 58.9% after the incubation for 12 or 24 hr respectively. Supplementation of this stuff with S. officinalis resulted in a significant reduc¬tion (P < 0.05) in vitro DMD (44.7 and 51.6%). The same trend was observed with the addition of R. officinalis to the A. halimus samples (44.8 and 532%). It would therefore appear that, the supplements used in the current study may have a negative effect on the in vitro dry matter digestibility of A. halimus.Istraživanje je provedeno radi proučavanja djelovanja dodavanja Atriplex halimusa sa suhim prahom aromatičnog bilja na in vitro probavljivost suhe tvari. 400+- 5 mg uzoraka suhog Atriplexa inkubirano je 12 ili 24 sata s puferiranom tekućinom iz buraga ovce i nadopunjeno sa 100 mg Salvie officinalis ili Rosmarinusa officinalis. Rezultati ovog istraživanja pokazali su da je in vitro probavljivost suhe tvari A. halimus bila 48,4% odnosno 58,9% nakon inkubiranja 12 odnosno 24 sata. Rezultat dodavanja S. officinalis bilo je znatno smanjenje (P<0.05) in vitro DMD-a (44,7 i 51,6%) Isti je trend primijećen dodavanjem R. officinalis uzorcima A. halimusa (44,8 i 53,2 %). Prema tome, izgleda da dodaci upotrijebljeni u ovom istraživanju mogu negativno djelovati na in vitro probavljivost suhe tvari A. halimusa
