Anotace: The aim of this experiment was to determine the influence of humic substances, and combination humic substances and selected phytobiotics on production and carcass parameters of broiler chickens. In experiment from total 200 one-day-old ROSS 308 chickens were randomized into four groups (n = 50). The control group was fed with basal diet (BD) without any additives. Group of chickens marked as treatment 1 (T1) was fed a BD containing 2% of humic acid, the group marked as treatment 2 (T2) was fed a BD containing 78% of humic acids, 18% of garlic powder (Allium sativum L.), 1% of milled dried leaves of wormwood (Artemisia absinthium), 1% of milled dried leaves of thyme (Thymus vulgaris), 1% of milled dried leaves of oregano (Origanum vulgare) and 1% of milled dried leaves of bogbean (Menyanthes trifoliata), together 2 kg /100kg complete feed mixture (BD). In the group marked as treatment T3 were chicken fed with BD containing industrially produced coccidiostats. Experiment lasted 42 days. At the end of the experiment was average body weight (values in the order of the groups: 1808.03 ±212.39; 1981.75 ±203.32; 1895.59 ±178.75 and 1955.31 ±237.16 g ±SD) significantly higher (P<0.05) in all treatment in compare to control group. In T2 was thigh part (29.27 ±1.50; 29.07 ±3.35; 30.45 ±2.15 and 29.49 ±2.34 mean ±SD) significantly higher (P<0.05) compared to control group. Carcass weight (values in the order of the groups: 1357.18 ±95.8; 1486.38 ±156.7; 1369.69 ±118.0 and 1440.68 ±132.1 g ±SD) and carcass yield (74.35 ±1.33; 76.10 ±1.97; 74.03 ±1.35 and 73.45 ±1.82 mean ±SD) were the highest in treatment T1 with humic acid addition (P>0.05).
