The topic of my dissertation is Comparison of the quality of eggs depending on the method of feeding. The aim of this study was to investigate whether the quality of hen eggs changes after adding crushed grape seeds in the compound feed of the hens. Grape seeds are formed as a side product during wine making processes and contain large amounts of biologically active substances and suitable acids, which can improve the feed conversion and subsequently also improve the technological properties of eggs. With processing of grape seeds the effective utilization of crop residues in vineyards comes about. The experiment was conducted in two experimental periods and in each period 100 laying hens were surveyed. They were separated into two groups an experimental and a control one. In the control group the hens were fed with a standard mixture of N2 feed and in the experimental group there was a supplement of 5 weight percent of crushed grape seeds in the compound feed. Eggs were collected daily and once every two weeks an analysis of technological properties of eggs was conducted. The results of the experiment showed that the addition of crushed grape seeds containing a biologically active substance did not have a statistically significant effect on the quality and selected technological parameters of eggs.
