The effect of diet on the content of selected heavy metals in rabbit meat (m. longissimus. lumborum) in mg/kg (w.w.).
| Heavy Metal | C (n = 20) 1 | N (n = 20) 2 | F (n = 20) 3 |
|---|---|---|---|
| Zn | 5.62 a ± 0.48 4 | 5.02 b ± 0.34 | 5.51 a ± 0.36 |
| Cu | 0.50 a ± 0.05 | 0.35 b ± 0.04 | 0.39 b ± 0.03 |
| Ni | 0.22 a ± 0.04 | 0.26 b ± 0.03 | 0.24 b ± 0.03 |
| Fe | 3.08 a ± 0.34 | 2.59 b ± 0.32 | 2.56 b ± 0.33 |
| Mn | 0.08 ± 0.01 | 0.03 ± 0.01 | 0.02 ± 0.01 |
| Cd | u.l.d. | u.l.d. | u.l.d. |
| Pb | u.l.d. | u.l.d. | u.l.d. |
w.w.—wet weight; u.l.d.—under the limit of detection; 1—control group, 2—diet with nettle leaves, 3—diet with fenugreek seeds; 4—results are presented as mean ± SD. a,b—means in rows with different letters are significantly different (p ≤ 0.05).
