The aim of the master's thesis was to process production and organizational data at Janjić Simmental Breed d.o.o. farm, and to compare the farm's production results with the production results of the Federation of Bosnia and Herzegovina. At the beginning of the thesis, the development of modern cattle breeding in the world, in Croatia, and in Bosnia and Herzegovina was described, as well as the cattle breeds most commonly raised in Croatia and Bosnia and Herzegovina. The organizational part of the farm was described in detail, i.e., the organization of feeding, milking, and other tasks on the farm. The main part of the master's thesis focused on the production indicators of Janjić Simmental Breed d.o.o. farm, i.e., the total milk production which was analyzed in all parameters, such as nutritional value, chemical composition, and quantity. The numerical status of cattle in all categories was analyzed in the thesis, as well as their movement through 2022 and 2023. The main goal of the research was to assess the status of Janjić Simmental Breed d.o.o. farm at the state level. By comparing the data for 2023, it was concluded that milk production at Janjić Simmental Breed d.o.o. farm is above the average of the Federation of Bosnia and Herzegovina in most analyzed parameters. I would particularly emphasize the high volume of milk production per head, which is a key indicator for milk producers. Based on the achieved results, it is concluded that production and organization on the farm are extremely good, and further progress is expected in the future.
