This thesis is dealing with effect of supplement limiting aminoacid histidin, that was applied as duodenal infusion, on yield and composition of high production dairy cows milk. The theoretical part describes overview about milk composition and metabolism of dairy cows. There are described nutrition requirements of dairy cows for esential aminoacids. In this part are also presented principles of analytical methods used for analysis of milk. For determination of basic components of milk were used infrared spectroscopy and enzymatic-conductometry. Aminoacid profile of casein was determined by ion exchange liquid chromatography. In the experimental part is described method of experiment. There is described technique of acid and oxidative hydrolysis of lyofilized casein and technique of determination aminoacids in this hydrolyzated casein. Results of analysis were interpreted and discussed with literature. This diploma thesis was made as a cooperation between the Institute of Food Science and Biotechnology, the Faculty of Chemistry, University of Technology, Brno and the Research Institute for Cattle Breeding, Department of Animal Physiology and Nutrition, Pohorelice.
