Genetic distances were studied among Czech Red cattle, German Red, Czech Pied, Polish Red, Czech Black and White, and German Black and White cattle. DA genetic distances were calculated, and trees were constructed using the Neighbour-Joining method. Evaluating the genetic distances by microsatellites, the lowest value was between Czech and German Black and(More)
Genotyping was carried out for glycogen storage disease type II and type V in seven cattle breeds. The analysis was carried out using the polymerase chain reaction/restriction fragment length polymorphism (PCR/RFLP) method. In the breeds analysed [Charolais, Czech Spotted (Czech Simmental), Belgian Blue, Limousine, Blonde d'Aquitaine, Aberdeen Angus, and(More)
A set of 233 Holstein calves, their 233 dams and 44 sires from 4 large-sized herds was genotyped for 10 microsatellites recommended by ISAG for paternity/parentage testing. Heterozygosity of microsatellites ranged from 0.607 (SPS115) to 0.835 (TGLA227), and PIC from 0.575 (SPS115) to 0.816 (TGLA227) confirming a high polymorphism of each analysed locus.(More)
The aim of the paper was to analyse congenital disorders in the Czech cattle population in 1986–2001. The offspring of 474 sires – 215 Czech Simmental, 236 Holstein, and 23 beef – were diagnosed with congenital disorders which were unevenly distributed because only 18 occurred in the progeny of 10 and more sires, in contrast to 88 occurring in the progeny(More)
In this paper, we analyse the occurrence of BLAD and CVM heterozygous animals in Holstein cattle in the Czech Republic in 1993-2005. The occurrence of BLAD heterozygous sires and heifers (BL) during the period 1993-1998 in Czech Holsteins was 13.9% and 10.7%. Radical measures have been taken to restore the population. Evidently, the measures have been(More)
The evaluation of an animal is based on production records, adjusted for environmental effects, which gives a reliable estimation of its breeding value. Highly reliable daughter yield deviations are used as inputs for genetic marker evaluation. Genetic variability is explained by particular loci and background polygenes, both of which are described by the(More)

Out of 5970 calvings, 4.29% had an abnormal course (dystocia). The occurrence of stillbirths was 6.98% of all births and 4.15% of normal course births. Stillbirths occurred in 70.31% of dystocias. The highest frequency of stillbirths was in Blonde d ́Aquitaine (8.59%) and the lowest in Gasconne (3.96%) cows. A narrow pelvis and an oversized foetus were the(More)
