Abstract

The research was carried out to evaluate the effect of phytochemicals with different properties on broiler chickens and to assess their synergistic effect in two- or three-component compositions. The objects of the research were broiler chickens, cinnamaldehyde (CA), quercetin (QU), and 7-hydroxycoumarin (COUM). The research scheme involved four variants: the control group of poultry fed the basic ration (BR) and experimental groups one, two, and three that received BR supplemented with CA (30 mg/kg feed) + QU (2.5 mg/kg feed), CA (30 mg/kg feed) + COUM (0.3 mg/kg), and CA (30 mg/kg feed) + QU (2.5 mg/kg feed) + COUM (0.3 mg/kg), respectively. On day 42 of the research study, the liveweight and the average daily liveweight gain in poultry of experimental group three increased by 30.83% (p ≤ 0.05) and 35.78%, respectively, over the entire growing period. Regardless of feed composition ingredients, feed consumption per 1 kg of liveweight gain in poultry of the experimental groups was lower than that in the control variant by 5.15–15.92%, while survivability index and the European broiler index, on the contrary, increased (by 2.0% and 29.6–107.9 (p ≤ 0.05), respectively). The dietary composition containing CA + QU + COUM contributed to increasing the gutted carcass weight and the muscle tissue weight by 23.94% (p ≤ 0.05) and 24.19% (p ≤ 0.05), respectively. The white blood cell counts in the poultry of groups two and three, compared to the control variant, increased by 19.6% (p ≤ 0.05) and 17.97%, respectively; the catalase activity levels elevated by 64.05% (p ≤ 0.05) and 57.48% (p ≤ 0.05), respectively. The serum crude protein content in the broiler chickens from experimental group three increased by 24.74% (p ≤ 0.05). In addition, significant (p ≤ 0.05) increases in the concentrations of albumin, AST, iron, and phosphorus with a decrease in the total bilirubin were observed. Therefore, the CA + QU + COUM composition used in the broiler chicken rations at the analyzed dozes is considered most appropriate for production process.
