Růst chladnokrevných hřebců v průběhu odchovu

The diploma thesis deals with the evaluation of the growth of cold-blooded stallions in pig breeding test rearing houses. The Czech Republic has set up three pig breeding test rearing houses. A total of 96 stallions were measured with 14 body measurements and they were also weighed whilst alive. Statistically significant differences were detected between breeds as well as between age groups when evaluating the intensity of growth of all measured body size and body weight. In most body sizes there were the biggest Silesian Norics horses (SN). At the age of two and a half years they stagnated growth in chest circumference, the circumference of the tibia and sternum height, even though it is stated in the Rules and Regulation of breeding book that SN mature between 5-6 years of age. During the evaluation there were no statistically significant differences between rearing houses. Stallions from the rearing house of Proseč prevailed in growth usually at the beginning of rearing, and later stallions from the rearing house of Dvorka at the age of one and a half year grew most. Stallions in the rearing house of Humňany had the lowest WHS, WHT and CC. The smallest variances of individual body size from the three studied cold-blooded breeds were detected by the CzechMoravian Belgian horse (CMB). This breed can therefore be regarded as the most well bred. The greatest value of the index body frame, the index heights in the crisis as well as index of severity were found in the breed SN. On the other hand CMB reached the lowest values in the above-mentioned indices and also in the index of boniness. Norick horses (N) have the most massive skeleton. In the scope of the height index of the sternum there was prevailed CMB at the beginning of rearing, but at the age of year and a half they began reaching a higher value N. This work was supported by the Project NAZV, project number QJ1510141 and project GAJU 019/2016/Z.
