Abstract
The aim of this study was to determine whether a mixture of medicinal herbs can be used to improve the resistance of broiler chickens to stressors during pre-slaughter handling. The hematological and biochemical parameters of broilers were analyzed. It was found that pre-slaughter management practices, including transport over different distances, caused stress in birds leading to changes in blood parameters. Long-distance transport (100, 200 and 300 km) contributed to a significant increase the concentrations of corticosterone and uric acid, and the values of hematocrit, leucocytes and the H:L ratio, and decrease the glucose concentrations. Broilers that received diets supplemented with medicinal herbs for 7 days were characterized by significantly higher hemoglobin levels, and a significantly lower H:L ratio and uric acid concentrations. A trend towards lower corticosterone concentrations and transaminase activity was also noted. The above indicates that a mixture of local medicinal herbs, containing goat’s rue, common nettle, lemon balm and common sage, can be used for stress prevention in broiler chickens, thus improving their welfare during the pre-slaughter period.
