| Item | B1 | G1 | P1 |
|---|---|---|---|
| pH | 6.74 ± 0.04 | 6.38 ± 0.05a | 6.47 ± 0.03b |
| Ammonia N, mM | 3.04 ± 0.17 | 8.73 ± 0.73a | 12.51 ± 0.87b |
| MCP, g/d | 8.47 ± 0.86 | 11.49 ± 1.22a | 9.31 ± 1.07 |
| Total VFAs, mM2 | 53.01 ± 2.00 | 78.67 ± 2.93a | 67.66 ± 3.57b |
| VFA, molar proportions | |||
| Acetate | 67.7 ± 2.2 | 58.8 ± 2.7 a | 70.6 ± 2.9b |
| Propionate | 21.1 ± 1.4 | 29.3 ± 2.4 a | 18.8 ± 2.6 |
| Butyrate | 11.2 ± 1.5 | 11.9 ± 1.4a | 10.6 ± 1.4 |
1Values are mean ± standard error (SE). 2Total VFA = Acetate + Propionate + Butyrate. a p < 0.05 in the two-tailed T-test of B group and G group. b p < 0.05 in the two-tailed T-test of B group and P group.
