Sledování antioxidační aktivity u brojlerových kuřat při zkrmování pšenice s netradičním zabarvením

The aim of the diploma thesis is the influence of feeding purple wheat Konini with the higher contents of athocyanins on the antioxidant activity measured in hybrid male chickens. For experiment were the animals divided into two groups of 32 each. Feed mixtures were prepared for each group. For the experimental group the wheat Konini was used. For the control group the common wheat was used, in which the protein content was increased by the wheat gluten. The feed consumption was daily monitored. The male chickens were fed exclusively by mono diet during the experiment in order to clearly demonstrate the influence of the monitored feed on the antioxidant activity. After the experiment blood and liver samples were taken. The antioxidant activity was measured by the methods DPPH, FRAP, FR and ABTS. The liver enzyme activities were measured from blood (ALT, AST, ALP and GMT). Significantly different values for methods DPPH, and ABTS, FR were proved by male chickens that were fed by the wheat Konini. The male chickens fed by the wheat Konini generally had lower activity of liver enzymes, but significant difference was in GMT activity in the male chicken's blood. The results show that the feeding of the higher content of anthocyanins improves the antioxidant activity and the condition of the liver tissue
