Comparison of slaughter performance and IMF between Nankou No. 1 and Jingdian Pekin ducks.
| Item 1 | Nankou No. 1 | Jingdian | p-Value |
|---|---|---|---|
| Live weight (kg) | 3.98 ± 0.04 | 3.92 ± 0.03 | 0.287 |
| Eviscerated yield (%) | 74.64 ± 0.88 | 75.50 ± 0.71 | 0.453 |
| Breast muscle yield (%) | 11.96 ± 0.24 A | 13.62 ± 0.25 B | <0.001 |
| Thigh muscle yield (%) | 9.51 ± 0.19 | 9.52 ± 0.18 | 0.976 |
| Abdominal fat yield (%) | 3.17 ± 0.10 | 2.93 ± 0.13 | 0.150 |
| Subcutaneous fat yield (%) | 40.06 ± 1.23 a | 36.22 ± 1.00 b | 0.022 |
| Intramuscular fat yield (Breast muscle, %) |
7.71 ± 0.05 A | 6.05 ± 0.04 B | 0.005 |
| Intramuscular fat yield (Thigh muscle, %) |
8.11 ± 0.22 A | 6.52 ± 0.29 B | <0.001 |
1 Eviscerated yield, % = eviscerated weight/live weight × 100; breast muscle yield, % = breast muscle weight/eviscerated weight × 100; thigh muscle yield, % = thigh muscle weight/eviscerated weight × 100; abdominal fat yield, % = abdominal fat weight/(abdominal fat weight + eviscerated weight) × 100; sebum yield, % = (skin weight + sebum weight + abdominal fat weight)/eviscerated weight × 100; intramuscular fat yield, % = (skin weight + sebum weight + abdominal fat weight)/eviscerated weight × 100. Different lowercase letters indicate significant differences (p < 0.05), and different superscript capital letters indicate extremely significant differences (p < 0.01). (n = 16 ducks: 8 ducks per group).
