The aim of this study was the assessment of an influence of dietary humic acids and dietary herbal additive (clove (Syzygium aromaticum), lavender (Lavendula angustifolia) and black pepper (Piper nigrum L.) on carcass parameters of Ross 308 broiler chicken (n=60). Broiler chicken were divided into 3 treatments (n=20). The chicken of the control group were fed with complete feed mixtures without any additives. Chicken in treatments T1 were fed a diet containing 1% of humic acid and drank a water containing 150 mg/l of dietary herbal additive, chicken in treatments T2 were fed with complete feed mixture without any additives and drank a water containing 150 mg/l of herbal additive. The carcass weight, weight of heart, liver, gizzard and neck without skin and carcass yield were evaluated. The carcass weight was in the treatment T2 statistically significantly higher (P=0.05) in compare with control group (values in the order of the groups: 1293.1±179.0; 1429.3±156.1 and 1531.6±282.3 g±SD). In the treatment T1 was weight of gizzard (43.7±7.5 g±SD) significantly higher (P=0.05) compared to control group (34.9±5.2 g±SD). In the treatment T2 was weight of liver (72.8±11.4 g±SD) significantly higher (P≤0.05) compared to control group (49.3±10.3 g±SD). In indicators weight of heart, weight of neck without skin and carcass yield were recorded nonsignificant different (P≥0.05) compared to the control group. [ABSTRACT FROM AUTHOR]
