Transportation plays important factor in broiler industry. Whole transportation process from loading tounloading can cause stress to broilers. The duration of the trip can affect oxidative stress, physiologicaland performance of broiler. This study aim to evaluate the effects of different transportation durationson oxidative stress, physiological responses and performance of broilers. Transportation from farm toslaughterhouse using a truck with a capacity of 144 crates. There were two durations treatment in this study,180 and 240 mins. Variables measured in this study were oxidative stress indicators (malondialdehyde/MDA content and catalase enzyme activity), physiological responses (rectal temperature and heterophilelymphocytes (HL) ratio), and performance represented by weight loss percentage. Normality test wasdone before T Test. Data analyzed using T Test independent which compared data between before andafter transportation. T Test dependent which compared data between short and long duration. The resultshowed that duration of transportation significantly affects on decrease liver and thigh catalase enzymeactivity, decrease malondialdehyde value on liver, decrease HL ratio after transportation, differenceson rectal temperature and weightloss. Long transportation duration resulted the lowest liver and thighcatalase enzymes activity (0.097±0.023 and 0.088±0.014 U/mL). It can be concluded that the long durationtransportation catalase enzyme activity reduce MDA value and affected performance indicator

AbstractThe oxidative stress and antioxidant systems in soybean leaves and roots infected with plant pathogen Aspergillus niger were studied following treatment with different concentrations of cholic acid. Several oxidative stress parameters were analyzed: production of superoxide (O2 ·−) and hydroxyl radicals (·OH), lipid peroxidation (LP), and superoxide dismutase (SOD; EC 1.15.1.1) activity, as well as the content of reduced glutathione (GSH). Results showed that inoculation with A. niger led to the increase of O2 ·− production and GSH quantities in leaves and ·OH in roots. The highest activity of SOD occured in infected plants treated with cholic acid in concentrations of 40 and 60 mg L−1 which ultimately led to a decrease in O2 ·− production. Inoculation with Aspergillus in combination with elevated cholic acid concentrations also increased ·OH production which is correlated with increased LP. These results may support the idea of using cholic acid as an elicitor to trigger hypersensitive response in plant cells. Use of cholic acid may also actively contribute to soybean plants defense response against pathogen attack.
