Abstract
In this study the effect of humic acids and humic acids and garlic powder (Allium sativum L.) combination on performance parameters and carcass characteristic of broiler chickens were studied. A total of 120 Ross 308 broiler chickens were divided into 3 treatments (n=40). The control group of chickens was fed complete feed mixtures without any additives. Treatment T1 was fed complete feed mixtures containing 1% of humic acid. Treatment T2 was fed complete feed mixtures containing 1.8% of humic acid and 0.2% of garlic powder (Allium sativum L.). At the end of the experiment was average body weight (values in the order of the groups: 1796.4±188.1; 1999.1±355.8 and 1958.6±201.2 g±SD) significantly higher (P≤0.05) in both treatments groups compared to control group. In T1 was weight of gizzard (values in the order of the groups: 34.9±5.2; 43.1±9.4 and 38.9±7.0 g±SD) significantly higher (P≤0.05) compared to control group. Carcass weight, weight of heart weight of liver and carcass yield of treatments groups was higher, but differences in these indicators were not statistically significant (P≥0.05). The results of this experiment indicate that humic acids may by an alternative replacement of feed antibiotics.
