Allele and genotype frequencies of milkprotein kappa-casein (CSN3) in artifical insemination bulls of Czech Fleckvieh and Holstein breed

Association between CSN3 and BCO2 gene polymorphisms and milk performance traits in the Czech Fleckvieh cattle breed.

Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for the bovine β-carotene oxygenase 2 (BCO2) gen...

Mapping of Transcription Factor Binding Region of Kappa Casein (CSN3) Gene in Iranian Bacterianus and Dromedaries Camels

κ-casein is a glycosilated protein in mammalian milk that plays an essential role in the milk micelles. Control of κ-casein expression reflects this essential role, although an understanding of the mechanisms involved lags behind that of the other milk protein genes. Transcriptional regulation, a first mechanism for controlling the development of organisms, is carried out by transcription facto...

Potential influence of κ-casein and β-lactoglobulin genes in genetic association studies of milk quality traits

OBJECTIVE From a review of published information on genetic association studies, a meta-analysis was conducted to determine the influence of the genes κ-casein (CSN3) and β-lactoglobulin (LGB) on milk yield traits in Holstein, Jersey, Brown Swiss, and Fleckvieh. METHODS The GLIMMIX procedure was used to analyze milk production and percentage of protein and fat in milk. Models included the mai...
