Bovine kappa-casein gene polymorphism and its association with milk production traits
Point mutations in exon IV of the bovine κ-casein (CSN3) gene determine two allelic variants, A and B. These variants were distinguished by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis in the indigenous Sahiwal and Tharparkar cattle breeds. DNA samples (252 Sahiwal and 56 Tharparkar) were analyzed for allelic variants of the CSN3 gene. Polymorphism ...
متن کاملGenetic polymorphism and association of kappa-casein gene with milk production traits among Frieswal (HF × Sahiwal) cross breed of Indian origin
The aim of the present study was to screen the genotype profile of bovine kappa-casein gene among Frieswal (HF × Sahiwal) crossbred cattle developed in India. A total number of two hundred Frieswal cows were evaluated for HinfI RFLP based genotyping of kappa-casein gene. We observed that only two genotypes (AA and AB) exist among the studied population with the genotype frequency of 0.58 (n=117...
متن کاملSingle nucleotide polymorphism of the lactoferrin gene and its association with milk production and reproduction traits in Iranian Holstein cattle
Bovine lactoferrin (LTF) is a member of the transferrin family of iron-binding proteins. This protein is present in a wide variety of biological fluids and shows important physiological functions in body. In this study, 404 blood samples were collected from Holstein dairy farms in Iran. A 301 bp fragment of intron 6 in bovine LTF gene was amplified and the animals were genotyped using polymeras...
متن کاملA PCR-RFLP investigation on PROP1 gene polymorphism and its association with milk production and growth traits in Mahabadi goats
Prophet of POU1F1 (PROP1) plays direct or indirect important roles in the morphogenesis of pituitary gonadotropes as well as lactotropes, somatotropes and caudomedial thyrotropes. It also controls the expression of growth hormone, prolactin and thyrotropin subunits through regulatory PIT1 factor. These hormones have important influences on production traits in most animal species including the ...
متن کاملStudy of Placental Lactogen Gene Polymorphism and Its Association With Milk Production Traits in The Holstein Cows
Placental Lactogen is a polypeptide hormone that is produced by the Placenta, also known as chorionic somatomammotropin hormone. It has both Growth Hormone and Prolactin activities on growth, lactation, and luteal steroid production. The objective of this study was to investigate the bovine Placental Lactogen (bPL) gene polymorphism of Holstein cows in Razavi Khorasan province. Blood samples we...
