The diploma thesis defines terms such as permanent grassland, clover grass, fod-der. The concepts are explained and clarified in the contexts that can be found between them. In connection with these concepts, the issue of cattle is mentioned in the work, in more detail Holstein cattle in the Czech Republic. The work is based on one-factor and multifactor analysis of variance (P <0.05), then the Post-hoc test was used, more precisely Tukey's test (P <0.05). The company where the analysis was performed – Hanácká zemědělská společnost a. s. (HZS Jevíč-ko), has area of grassland262.04 ha. Of these stands, four species were included in the analysis, namely permanent grassland renewed, permanent grassland not rene-wed, alfalfa grassland I. useful year and alfalfa grassland II. utility year. The analysis determined nutrients crude protein (CP), crude fiber (CF), acid detergent fiber (ADF) and neutral detergent fiber (NDF). The stated values come from our own laboratory analyzes of grass and alfalfa stands and on the basis of their results feed rations were compiled according to the requirements for dairy cows weighing 600 kg with a milk yield of 28 l FCM. After the compilation of these batches, an economic evaluation of their profitability in the individual sampling dates and a comparison with the date of the company's actual harvest followed. From the point of view of the feed ration, the first one was evaluated as the most suitable date for the harvest of permanent grassland, where compared to the actual harvest the savings are made (with 895 dairy cows) in the amount of CZK 1,211,964. The amount of savings in permanent grassland not renewed would be CZK 2,904,141. In contrast to these two stands, it does not show alfalfa grass I. useful year between the first date and the real harvest date no price difference. It manifested itself only in the alfalfa vegetation vegetation II. useful year, in the amount of CZK 427,944.
