Impact of dietary fennel oil or gentamycin on the relative weights of carcass cuts and internal organs of weaned Moshtohor rabbits aged 12 weeks.
| Parameters | Control | Fennel | Gentamycin | SEM | p Value |
|---|---|---|---|---|---|
| Carcass cuts | |||||
| Live body weight (g) | 1443.00 b | 1684.67 a | 1700.67 a | 36.28 | 0.0004 |
| Carcass (%) | 51.20 | 45.06 | 47.03 | 2.43 | 0.2656 |
| Head rate (%) | 7.29 a | 6.20 a,b | 5.52 b | 0.356 | 0.0336 |
| Hind legs rate (%) | 14.03 | 13.11 | 15.33 | 1.034 | 0.3730 |
| Saddle rate (%) | 10.33 | 9.57 | 10.69 | 0.414 | 0.2269 |
| Fore legs rate (%) | 10.20 | 9.73 | 10.25 | 0.239 | 0.3155 |
| Thoracical neck rate (%) | 12.42 | 9.65 | 13.57 | 1.254 | 0.1546 |
| Body organs (%) | |||||
| Liver (%) | 2.86 | 2.70 | 2.38 | 0.169 | 0.2125 |
| Kidney (%) | 0.672 | 0.584 | 0.559 | 0.047 | 0.2832 |
| Spleen (%) | 0.074 | 0.069 | 0.049 | 0.009 | 0.1949 |
| Lung (%) | 0.739 | 0.613 | 0.676 | 0.068 | 0.4748 |
| Heart (%) | 0.309 | 0.267 | 0.235 | 0.021 | 0.1252 |
All data are expressed as the mean with SEM in same row; a,b letters indicate significant differences between means (p < 0.05). Rabbit sample/group, n = 5. The parameters rate and organ index were calculated as follows: parameters rate or organ index = (organ weight/living weight) × 100%.
