Evaluation of antimicrobial effect of olive leaves powder and its role in improving the broiler productivity, carcass traits, blood metabolites, and caecal microbiota
The present study aims to evaluate the antimicrobial activity (in vitro study) of olive leaves powder (OLP) and its role in improving the broiler productivity, carcass criteria, blood indices, and antioxidant activity. A total of 270 one-day-old broiler chickens were distributed into 6 treatment gro...

description | The present study aims to evaluate the antimicrobial activity (in vitro study) of olive leaves powder (OLP) and its role in improving the broiler productivity, carcass criteria, blood indices, and antioxidant activity. A total of 270 one-day-old broiler chickens were distributed into 6 treatment groups as follows: the first group: basal diet without any supplementation, while the second, third, fourth, fifth, and sixth groups: basal diet supplemented with 50, 75, 100, 125, and 150 (µg/g), respectively. The in vitro study showed that the OLP has good antibacterial activity in the concentration-dependent matter; OLP 175 µg/mL inhibited the tested bacteria in the zones range of (0.8–4 cm), Klebsiella Pneumonaie (KP) was the most resistant bacteria to OLP concentration. The antioxidant activity of OLP increased with increasing the concentration of OLP compared to ascorbic acid, where OLP 175 µg/mL scavenged 91% of 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radicals compared to 93% scavenging activity of ascorbic acid. Broiler chickens fed diets with OLP had significantly (P < 0.05) higher body weight (BW) and body weight growth (BWG) than the control birds. The treatment with OLP significantly reduced the feed intake (FI) and feed conversion rate (FCR) when compared to control. Groups supplemented with OLP showed decreased abdominal fat deposition and a significant increase in the net carcass and breast muscle weight. OLP improved birds’ blood parameters in comparison with control birds. All pathogenic bacterial numbers in caecal samples were decreased with elevating OLP levels, but the cecal Lactobacillus bacterial count was increased. In conclusion, OLP supplementation improved broiler chickens’ performance, carcass traits, and blood parameters. Moreover, OLP improved birds' liver functions (reduced Alanine transaminase [ALT] and aspartate aminotransferase [AST] levels) in comparison with control. In addition, OLP promoted the antioxidant status, minimized the harmful microbial load, and increased beneficial bacterial count in the cecal contents of broilers. |
