The donkey population in Central Europe and Czech Republic is very variation, which is a consequence of the donkeys originating from various areas of Europe. This has been proved to affect their body conformation. In this work, we are focusing on the population of donkeys in the Czech Republic and its analysis.The main aim of our work was to determine the values morphological parameters in the donkey population in the Czech Republic. Altogether, 23 body dimensions were taken and further processed to calculate 6 hippo metric indexes. The sample group we analyzed consisted by a total of 70 individuals, out of there were 23 stallions and 47 mares. The results were then processed using the methods of general linear model (GLM) and multiple comparisons.We managed to prove a statistically significant influence of the sex factor for the following body measurements: shin length of the front limbs, chest width, withers height measured by tape, shin circumference on both front and pelvic limbs and also for weight index. Also, we have found a statistically significant difference in the scapula length when considering the age factor.

The objective of the present study was to evaluate the effect of the breed of sire and line of sire on grading of the body conformation and performance of colts of warmblood horses in rearing facilities for testing young horses (RFT). The groundwork database contained data from 2001 to 2011 from nine RFT’s. The database was processed statistically using the GLM method to assess the statistical significance of the effect of the breed of the sire and line of the sire on body conformation and performance of the colts. By multiple comparisons of the individual effects using the Tukey-B method we discovered statistically significant differences in the body conformation and performance of colts of sires among the respective breeds and lines. The performance of the offspring of Dutch warmblood, Hanoverian horse and Holsteiner horse sires is better than of the offspring of sires of the Thoroughbred, Czech warmblood and Selle Francais. The conformation of the offspring by sires of the Holsteiner horse and Hanoverian horse breeds is superior to that of offspring by sires of the Selle Francais and Czech warmblood. The mechanics of movement of the offspring of the 2300 Shagya XVIII-Báb. line is inferior to the offspring of the following lines: 3100 Adeptus xx, 67 Dark Ronald, 1000 Der Lowe xx, 3250 Dwinger 3257, 4800 Ladykiller xx, Orange Peel xx – Alme Z, 1100 Przedswit VI-Rad., 4900 Rantzau xx – Cor De La Bryere, 4600 Rittersporn xx – Ramzes 4028, 60 St. Simon and 88 Teddy. The effect of the line of the sires on the body conformation of colts has not been proved.

The objective of the present study was to analyse the numbers and division of horses of undefi ned breed. At the present time this group is the most numerous in the entire population of horses. Horses of undefi ned breed do not come under any breeder union which would provide reports about these horses; these horses are only registered and breeders are informed only about their numbers. Our study is the fi rst to deal with the problem of increasing numbers of horses of undefi ned breed. The database contained 22 211 horses not entered registered in any of the stud books. In the database we fi led approved horses born between 1972 and 1 September 2012 and horses registered from 1987. The data were processed in the Excel programme and results were evaluated in graphs. The most frequent horse in this group was the warm-blood type (n = 9 303), pony type (n = 6 285), cold-blooded type (n = 2 663) and unlisted horses (n = 2 278). Since 2001 the number of registered horses of undefi ned breed has increased. The most numerous dams of horses of undefi ned breed is the Czech warm-blood with 1 912 off spring; dams of the English Thoroughbred with 552 off spring and mares of the utility Huzule horse with 492 off spring. In the group of registered horses of undefi ned breed the Czech warm-blood appears in the pedigree of 507 colts and the American Paint Horse in the pedigree of sires of 506 colts. Why the numbers of horses of undefi ned breed are increasing is the boom of leisure horsemanship and unqualifi ed horse breeding.

The objective of the present study was to compare the individual breeds of Hutzul horses in Slovakia and in the Czech Republic in terms of their age, gender, line and conditions of breeding in which the horses live. First of all in each herd we analysed 14 body dimensions, from these data the hippo-metric indices were calculated and processed statistically using the statistical programme Unistat version 5.1. Then they were compared mutually. Most of the statistically signifi cant diff erences were related to the eff ect of the place of measurements. According to the place of measurement only the tape measure and height in saddle were statistically insignifi cant. On average the largest horses come from the ranch in Janova Hora and the smallest from the Slovakian Hutzul Club and Zmrzlík. In the eff ect of a gender the geldings exhibited the highest average values of all the dimensions, with the exception of the front width of pelvis, while the stallions showed the lowest (with the exception of the cannon girth). In the eff ect of a line the average values were the highest in the Prislop line and the lowest in the lines Hroby and Gurgul. The age aff ected only one dimension, i.e. the chest width behind the shoulder blade. Eight-year-old horses exhibited the highest average values and 3-year-old and 19 to 20-yearold horses the lowest values.
