|---|---|---|---|---|
| Items | NC | Arg | SEM | p-Value |
| Eviscerated yield (%) | 65.36 | 66.89 | 0.910 | 0.320 |
| Heart (%) | 1.06 | 1.09 | 0.213 | 0.931 |
| Liver (%) | 2.00 | 1.83 | 0.100 | 0.418 |
| Gizzard (%) | 2.30 | 2.23 | 0.150 | 0.851 |
Eviscerated yield (%) = Eviscerated carcass weight/live body weight ∗ 100; Heart (%) = Heart weight/live body weight ∗ 100; Liver (%) = Liver weight/live body weight ∗ 100; Gizzard (%) = Gizzard weight/live body weight ∗ 100; NC = non-injected control group. Arg = 1% L-arginine-injected group. SEM = standard error of the mean. Values are means with n = 8 per treatment.
