Growth performance data and apparent total tract nutrient digestibility of crude nutrients in weaned pigs fed a control diet or a diet supplemented with 1% grape seed and grape marc meal extract (GSGME) or 1% spent hops (SH)
| Control | GSGME | SH | |
|---|---|---|---|
| Growth performance data | |||
| Initial body weight (kg) | 9.8 ± 0.5 | 10.0 ± 0.5 | 9.9 ± 0.6 |
| Final body weight (kg) | 23.7 ± 2.6 | 24.1 ± 2.1 | 23.4 ± 2.0 |
| Daily feed intake (g)1 | 828 ± 115 | 789 ± 85 | 762 ± 53 |
| Daily body weight gain (g) | 497 ± 63 | 509 ± 74 | 497 ± 77 |
| Gain:feed (g/kg)1 | 579 ± 68 | 620 ± 53# | 638 ± 83* |
| Apparent total tract digestibility (%) | |||
| Crude protein | 81.9 ± 3.5 | 81.0 ± 2.3 | 78.0 ± 1.4* |
| Crude fiber | 55.1 ± 11.8 | 51.4 ± 7.6 | 45.1 ± 8.7* |
| Crude fat | 65.0 ± 3.4 | 70.0 ± 3.0* | 66.2 ± 3.3 |
| N-free extract | 90.1 ± 2.4 | 89.9 ± 2.8 | 89.4 ± 1.1 |
| Organic matter | 80.3 ± 2.5 | 80.1 ± 2.3 | 78.7 ± 1.5# |
Results are shown as mean ± SD (n = 16/group). 1Means of two pigs per pen were averaged. *Significantly different from control (P < 0.05). #Tended to differ from control (0.05 ≤ P ≤ 0.10).
