Abstract: [cze] [eng]
Kvalita mléka je u skotu ovlivňována řadou genů. Jedním z nich je i gen CSN2. Cílem této diplomové práce bylo testování souboru zvířat o 240 jedincích plemene jersey a brown swiss v České republice. DNA byla izolována z krve. Pomocí sekvenace byly stanoveny jejich genotypy a vypočteny genotypové a alelové frekvence. Dále byla v programu SAS provedena asociační analýza jednonukleotidového polymorfismu s parametry mléčné užitkovosti. Vybranými parametry byly laktační dny, dojivost (kg/laktace), obsah tuku v mléce (% a kg) a obsah bílkovin (% a kg). Tyto parametry byly k dispozici u 126 jedinců. Ve zkoumaném souboru nebyl prokázán statisticky průkazný vliv genotypu CSN2 na zvolené znaky. Jako statisticky průkazný vyšel pouze efekt plemene. The quality of milk in cattle is influenced by many genes. One of them is gene CSN2. The aim of this diploma thesis was to test animal population of about 240 individuals of Jersey and Brown Swiss breed in Czech Republic. DNA was isolated from blood. Genotypes were determined by sequencing followed by determining genotypes and alleles frequencies. The association analysis of single nucleotide polymorphism with milk yield parameters was performed by using SAS program. The selected parameters were lactation days, milk yield (kg), fat content in milk (% and kg) and protein content (% and kg). These parameters were available for 126 animals. Statistically significant effect of CSN2 genotype on the selected milk production traits was not found in the studied population. Only effect of breed was found as statistically significant.
