Table 2. The effect of ammoniated PPF on the DMD, OMD, VFA, and N-NH3.
| Item | Treatment | ||
|---|---|---|---|
| Con | A-4 | A-Mul | |
| DMD | 44.75a ± 2.12 | 52.00a ± 4.06 | 73.10b ± 3.39 |
| OMD | 25.50a ± 9.84 | 29.93a ± 7.57 | 47.09b ± 4.04 |
| TVFA | 93.14a ± 8.76 | 95.66ab ± 14.32 | 114,89b ± 5.12 |
| N-NH3 | 3.74a ± 0.17 | 5.16b ± 0.82 | 4.27ab ± 0.39 |
Con = untreated PPF; A-4 = urea 4%; A-Mul = urea (6%,4%,2%); DMD = dry matter digestibility; OMD = organic matter digestibility; TVFA = total volatile fatty acids; N-NH3 = ammonia.
Means with different superscript letters in the same line differ significantly (p < 0.05).
