The aim of this thesis was to compare different systems of calf nutrition. Holstein heifers (n = 30) were divided into two groups of 15 calves. Both groups were housed in outdoor individual sheds and fed the same type o milk feed – at the same amount and concentration. The first group was fed by two different structural starter mixtures to 29th day of calf age. From 30th day of calf age was fed straw-type starter mixtures. The second group was fed one starter mixture of straw. During operating trial lasted until the 60th day of calf age were monitored consumption of starter mixture, growth performance, consistency of faeces and economic aspect of rearing calves. The consumption of the starter mixture was up to day 30 higher in the second group of calves which were fed straw starter mixture, but from day 30th of calf age consumption was higher for the first group, but this difference is not statistically significant. The daily growth performance and consistency of faeces were also very similar and the difference between two groups was not statistically significant. The cost of a really used starter was almost the same for both groups of calves. For this reason, both rearing systems are evaluated positively and can be recommended in practice.
