Abstract: Increased atmospheric carbon dioxide (CO 2 ) is a consequence of recent anthropogenic environmental changes, and few studies have evaluated its effects on tropical grasses used in Brazilian pastures, the main feed source for major part of ruminant livestock. This study evaluated forage production, chemical composition, in vitro total gas pro‐ duction and organic matter degradability of Brachiaria brizantha under contrasting CO 2 atmospheric conditions in a free air carbon dioxide enrichment (FACE) facility. The forage plants were sown in each of the 12 octagonal rings of the FACE facility: six under ambient atmospheric CO 2 concentration of approximately 390 μmol/mol, here‐ after referred to as control (CON) plots, and other six rings enriched with pure CO 2 flux to achieve a target CO 2 concentration of 550 μmol/mol, hereafter called elevated CO 2 (eCO 2 ) plots. Soil samples were collected to determine carbon and nitrogen con‐ centrations. After seventy days of sowing, a standardization cutting was performed and then at regular intervals of 21 days the forage was harvested (ten harvest dates) and forwarded to laboratorial analyses. Forage above‐ground biomass production (dry matter (DM): 6,143 vs. 6,554 kg/ha), as well as morphological characteristics (leaves: 71% vs. 68%; stem: 28% vs. 31%), chemical composition (crude protein: 162.9 vs. 161.8; neutral detergent fibre: 663.8 vs. 664.3; acid detergent fibre: 369.5 vs. 381; lignin: 60.1 vs. 64.1 g/kg DM; total C: 45.9 vs. 45.9; total N: 2.8 vs. 2.8; total S: 0.2% vs. 0.2%), organic matter in vitro degradability (573.5 vs. 585.3 g/kg), methane (5.7 vs. 4.3 ml/g DM) and total gas (128.3 vs. 94.5 ml/g DM) production did not differ signifi‐ cantly between CON and eCO 2 treatments (p > .05). The results indicated that at least under short‐term enrichment, B. brizantha was not affected by eCO 2 .
