GENETIC DIVERSITY IN CZECH HAFLINGER HORSES

The Haflinger as a small moutain horse breed originated from the South Tyrol district as a cross of Alpen Mountain breeds with Araber. This breed was expanding to Czech Republic during the last 25 years. The aim of this study was to analyse genetic diversity within the population using microsatellite markers. A total of 95 alleles have been detected. The highest frequency 88.18% showed allele 101 (HTG 6). The heterosigosity varied from 0.25 (HTG 6) to 0.84 (VHL 20), genetic diversity reached 0.6–0.8. The heterozygosity of the whole population studied is FIS= -0.013. The average effective number of allele per locus was 2.93 with standard deviation 1.54, with minimal and maximal level 1.30 and 7.83, respectively. Average polymorphism information content per locus was 0.608 with standard derivation 0.146, with minimal and maximal level 0.208 and 0.824, respectively. The results showed that breeding program of Czech Haflinger is optimal, including optimized mating strategies. The diversity of the population Czech Haflinger, based on a small number of microsatellites, seems to be sufficient

Genetic parameters for first calving interval in beef cattle

The aim of this study was to estimate genetic parameters for first calving interval in beef cattle population of the Czech Republic. Database of performance testing of 64 thousand of cows with repeated records was used to analyse. There were significant effects (P<0,001) of age at first calving, herd-year-season, breed, calving difficulty and heterosis of cow (P=0.038). Genetic parameters were estimated by AIREML. Heritability of first calving interval (0.1) was estimated

Diagnostics of the Special Laerning and Behavioural Disorders and Affection of Progression of Children with these Disorders

The bachelor thesis deals with diagnostics of the special learning and behavioural disorders and affection of progression of children with these disorders focuses on special learning and behaviour disorders, its diagnostics and rehabilitation. It is dedicated to parents and educators of children with these disorders. The special education disorders may not appear in learning the school stills (e.g. reading, writing and counting) but very often they appear in other spheres (e.g. senses), which is the presupposition built upon the author's experience. These sensual disorders may become obstacles in learning the school stills leading to failure. This work also stresses possible disorders and problems within social and emotive sphere resulting from learning and behaviour disorders. The objective is to lead the parents and educators to active assistance to these children in surpassing of these difficulties and inadequacies. That is why this work offers not only fundamental information about the character of special learning and behaviour disorders, their diagnostics and symptoms in partial areas, but also concretes the chosen topics and ideas for activities designed to a support of the children with special learning and behaviour disorders, reeducation and compensation of their difficulties. This work builds..

Genetic Parameters for Limousine Interbeef Genetic Evaluation of Calving Traits

The aim of this study was to estimate across-country genetic correlations for calving traits (birth weight, calving ease) in the Limousine breed. Correlations were estimated for eight populations (Czech Republic, joint population of Denmark, Finland, and Sweden, France, Great Britain, Ireland, Slovenia, Switzerland, and Estonia). An animal model on raw performance accounting for across-country interactions (AMACI) was used. (Co)variance components were estimated for pairwise combinations of countries. Fixed and random effects were defined by each country according to its national genetic evaluation system. The average across-country genetic correlation for the direct genetic effect was 0.85 for birth weight (0.69–0.96) and 0.75 for calving ease (0.62–0.94). The average correlation for the maternal genetic effect was 0.57 for birth weight and 0.61 for calving ease. After the estimation of genetic parameters, the weighted bending procedure was used to compute the full Interbeef genetic correlation matrix. After bending, direct genetic correlations ranged from 0.62 to 0.84 (with an average of 0.73) for birth weight and from 0.58 to 0.82 (with an average of 0.68) for calving ease

Effects of crossbreeding on milk production of sheep

The aim of this study was to estimate the effects of crossbreeding on milk production and milk components in crossbred Tsigai, Lacaune, and Improved Wallachian sheep used to create a synthetic Slovak dairy sheep population. The local breeds Tsigai and Improved Wallachian were crossed with the high-yielding breed Lacaune to increase milk yield. The effects of crossbreeding were evaluated based on breed and heterosis effects. The database used consisted of 23 018 lactations from 15 888 ewes. The effects of crossbreeding on milk production and fat and protein content were estimated using the restricted maximum likelihood method in REMLF90. Fixed effects on milk yield were also studied. In ewes with a 100% heterosis effect (ewes from purebred parents of different breeds), the heterosis effect increased milk production by 11.642 kg, milk fat production by 0.772 kg, and protein production by 0.565 kg per milking period. The effect of the Tsigai breed on milk production was -21.98 kg compared to Lacaune, while for the Improved Wallachian breed, the value was -38.58 kg. The Tsigai direct breed effect reduced fat production by 1.56 kg and protein production by 1.34 kg. The Improved Wallachian direct breed effect was -2.71 kg for fat production and -2.27 kg for protein production

POPULATION STUDIES OF CZECH HUCUL HORSES

Population studies were carried out analysis Czech Hucul breed based on pedigree information of animals registered in the Studbook. Pedigree records collected from the year 1834 to 2013 comprised information on 9455 animals used in the analyses. The pedigree depth of the analysed individuals was up to 19 generations. The mean value of inbreeding coefficient was 5.35% (with maximum value 30%). The proportion of inbreed animals was high (98%). The average rate of inbreeding in the reference population was lower than 1%, and the respective estimates of effective population sizes were 54. The presented paper is indicating that genetic diversity in the Czech Hucul breeds is still relatively high and conservation programs should be continued
