The diploma thesis entitled "Evaluation of the influence of the composition of the feed mixture on the change in biochemical parameters of the blood plasma of broiler chickens" deals with the composition of the feed mixture and its effects on the internal environment and growth performance of broiler chickens. The aim was to develop a literature search on the topic of feeding broiler chickens and the biochemical parameters of blood plasma. Furthermore, check whether the supplemented feeding doses of milk thistle (Sylibum marianum L.) and the commercially produced preparations Presan - FY and Selko pH affect the indoor environment’s growth intensity and parameters. In the experiment, 3 control weighings and one final weighing were carried out, in which the actual increase was determined. Next, blood was taken into a tube with heparin, from which blood plasma was obtained for analysis of biochemical parameters. The data obtained from the analysis were statistically evaluated and statistically significant. A statistically significant difference was noted in the concentration of total bilirubin between groups O and K (p<0.05), but also between groups O and P (p<0.01), and there was also a statistically significant difference in the concentration of glucose between groups P and O (p<0.001) and also between P and K (p<0.01). The catalytic concentration of glutathione peroxidase was statistically significant between the O and P groups (p<0.05). There was a statistically significant difference in beta-hydroxybutyrate concentration between groups P and O (p<0.001), but also between groups P and K (p<0.05). Phosphorus concentration was statistically significant between K and O groups (p<0.01) and cholesterol concentration had a significant difference between O and K groups (p<0.001) and between O and P groups (p<0.05). There was a statistically significant difference in the concentration of non-esterified fatty acids between groups O and K (p<0.001), but also between groups O and P (p<0.05). Lactate dehydrogenase concentration was statistically significant between O and P groups (p<0.05) and creatine kinase level was statistically significant between O and K groups (p<0.01). It can be seen from the work that supplementation according to the methodology of the experiment influenced the growth intensity, the results of the measurements of the monitored environment of the animals and also the parameters of the inner environment of broiler chickens.
