In the Republic of Croatia, the Lipizzan horse breed is included in the group of protected breeds. The Đakovo stud farm carries out its breeding and selection work according to the breeding program of the Lipizzan breed in the Republic of Croatia. It is also a member of the Lipizzan International Federation (LIF) connecting them in breeding goals and principles. The state stud farm Đakovo currently breeds 7 lines of stallions, 11 breeds of mares, and has 178 horses of the Lipizzan breed at two locations. Out of the total number of horses, mares are the most represented, followed by stallions, which together make up about 60% of the herd. Within the framework of this paper, the numerical condition and the representation of lines and breeds of Lipizzan horses in the Đakovo State Stud for the past 10 years (2012 - 2021) were analyzed. From the analyzed data, we can see that the most represented lines are Maestoso, Siglavy and Neapolitano, followed by Conversano, Favory and Tulipan, while Pluto is the least blunted line. Analyzing the collected data on the number of mares, the most represented genera are Mara, Montenegro and Mima, while the least represented is the genus Krabbe. Observing the overall analysis of graphs and tables, according to the lines and breeds of stallions and mares, we can see that good and high-quality planning of breeding and selection is a very complex job, which requires a lot of effort, knowledge and skills to preserve the representation and uniformity of the lines in order to obtain the best possible quality descendants.
