Study of genetic distances between cattle breeds of Central Europe
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 White breeds. A surprisingly high valu...
متن کاملKappa-casein Genotypic Frequencies in Russian Breeds Black and Red Pied Cattle
Casein is a family of milk proteins that exists in several molecular forms and is the main protein present inthe bovine milk. The B variant of bovine k-casein is reported to be favorable for quality and quantity of cheese derived from milk and considered to be included in breeding strategies of dairy cattle. Genotypes of72 Russian Black Pied and 80 Red Pied cows were determined for ...
متن کاملAnalysis of genetic structure in Polish Red and Polish Black-and-White cattle using twelve marker loci potentially related to milk or meat production traits*
Polish Red (PR) is the native Polish cattle breed included in the FAO National Rare Livestock Breeds Preservation Programme. The breed is characterized by high vitality and fertility, calving ease, resistance to diseases, and low requirements for feed. Milk yield is low, but fat and protein content of milk are high. The frequencies of alleles of commonly studied loci as well as the presence of ...
متن کاملAssociation of Prolactin Gene Variants with Milk Production Traits in Russian Red Pied Cattle
A total of 125 Russian Red Pied cows were genotyped for the prolactim-related gene. The PRL-RsaI genotypes were analysed using the Polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP) method. In this breed, the frequencies of alleles were as follows; A= 0.794 and B= 0.206. The frequencies of AA, AB and BB genotypes were 0.598, 0.392 and 0.01; respectively. Results sho...
متن کاملSingle nucleotide polymorphism discovery in bovine liver using RNA-seq technology
BACKGROUND RNA-seq is a useful next-generation sequencing (NGS) technology that has been widely used to understand mammalian transcriptome architecture and function. In this study, a breed-specific RNA-seq experiment was utilized to detect putative single nucleotide polymorphisms (SNPs) in liver tissue of young bulls of the Polish Red, Polish Holstein-Friesian (HF) and Hereford breeds, and to u...
