【 摘 要 】
This study was conducted to determine the interference of Salmonella typhimurium lipopolysaccharide (sLPS) on the performance, biological parameters, and histological evaluations of 198 one-day-old male broiler chickens divided into three treatments according to sLPS dose (0, 250, or 500 µg/application/bird) that was applied to the birds every other day, from 15 to 27 days of age. At the end of the experiment (28 days), significant effects were observed on body weight (R= -0.17 and P=0.05), total cholesterol serum levels(R=0.43 and p<0.01), phosphorus (R=0.53 and P<0.01), uric acid (R= -0.38 and P<0.01), C-reactive protein (R=0.68 and p<0.01), serum activity of aspartate aminotransferase (R=0.39 and p<0.01) and alkaline phosphatase (R= -0.39 and p<0.01). According to these results, sLPS mainly affect broiler biological parameters, but also their live performance.
