Popis: This study aimed to investigate the effect of red grape pomace (RGP) treated with ozone (O3) gas as a substitute of low-quality alfalfa hay on the ruminal fermentation, nutrient digestibility, and milk production performance of fat-tailed, fed RGP substituted high fibrous alfalfa hay. Present study was performed in two experimental phases: 1) In situ and in vitro phase: Four Ghezel ewes in their third gestation (30 months old; weighing 51 ± 2 kg) with surgically implanted cannulas in their rumen were used to assess the in situ degradability and to obtain ruminal fluid to assay the in vitro gas production; the treatments were RGP not-processed (control; T0), and RGP processed with O3 for 6 (T1), 12 h (T2), and 24 h (T3). Processing RGP with O3 gas reduced (P
