Effect of Zataria Multiflora Extract on Degradability Kinetics, of Sunflower Meal

The aim of the present study was conducted to survey effect of adding different levels (0, 0.15, 0.3 ml/30ml buffered rumen fluid) of Zataria multiflora water extract (ZMWE) on sunflower meal (SM) degradability were studied by in vitro gas producing techniques. Gas production test with mixtures of filtered rumen liquid of three Taleshi native male cattle rumen in times of 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours were performed. Chemical composition for dry matter, crude protein, and Non-Fibrous Carbohydrate 95.88, 30, and 12.73 percent, respectively. The results showed that gas volume at 24 h incubation (for 200 mg dry samples), were 42.40, 41.41 and 40.52 ml/200 mg DM for SM, levels 0.15 ZMWE and 0.3 ZMWE, respectively. the gas production from soluble fraction (a), the gas production from insoluble fraction (b), rate constant of gas production during incubation (c) and the potential gas production (a + b) contents of SM were 3.607 (ml/200 mg DM), 49.32 (ml/200 mg DM), 0.135 (ml/h) and 52.92 (ml/200 mg DM), while for level 0.3 ZMWE were 4.655 (ml/200mg DM), 48.66 (ml/200 mg DM), 0.134 (ml/h) and 53.321 (ml/200mg DM).
