Hodnocení počtu a kvality potomstva hřebců slezského norika / Evaluation number and quality of offspring stallions Silesian noriker

The Silesian noriker is an original Czech breed of a coldblooded horse whose stud book was approved by the Ministry of Agriculture in 1995.The Silesian noricker is a strong coldblooded horse with a relatively less harmonious body structure used at present not only in agriculture and forestry but also for rehabilitation and recreation purposes. The aim of the diploma work was to work out a list of information about stud horses being in the contemporary stud as noted down in the stud book. Besides, the work focuses at proving a possible existence of the differences between the outcome of the evaluation of the exterior, performance tests and the characteristic features inherited by the descendants of the stallions. Moreover, the main aim of the work was to find out if there are individuals among stud stallions which have sufficient number of descendants being able to provide an objective evaluation of heredity control. Studbook Silesian noriker recorded 44 sires, of which only 23 subjects had descendants in breeding; the number was 266 individuals. The stud book of the SN kept files of 44 stud stallions out which only 23 individuals had descendants in stud, whose number was 266. The data for the purpose of the analysis have been based on the records in the stud books of the association of the unions of horse breeders: body measurements, evaluation of the exterior and the results of the performance tests. All the data have been presented and evaluated both in charts and graphs. In conclusion, stallions having 10 and more descendants have been evaluated in detail and the results of the latter have been compared with the average ones of SN in stud. The analysis has proved that only 68% of the whole number of descendants is represented by those written in the stud book of SN. The average body measurements were: stick withers 159,07 cm; tape withers 170,88 cm, chest perimeter 204,85 cm, shin perimeter 23,20 cm. The evaluation of the exterior showed the average result 7,47 points. The final result of the performance tests was 7, 47 points. According to the detailed analysis, out of 75 descendants only 44% belonged to SN. The Top rated offspring (exterior 7,76 and results performance tests 8,03) had of stallion Steiman 2885
