The objective of this study was to determine the polymorphism of bovine β-lactoglobulin (β-LG) gene and its association with milk production traits in Iranian Najdi cattle. Blood samples were collected from 80 Najdi cattle from the Najdi cattle breeding station located in Shoshtar, Khuzestan. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniqus were used...

Objective: Identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. Methods: Najdi Cattle is the most prominent breeds in Khuzestan province. To do this plan in Shoushtar Najdi Cattle Station, blood samples were taken from 15 Najdi Cattles. DNA was extracted from wh...

more than 80% of the total milk protein contains caseins that are to forms α-s1, α-s2, β-casein and kappa casein. kappa casein is smaller than other milk proteins but due to have a role in size and stability of micelles. the present study describes polymorphism of kappa casein gene. this is the first study of kappa casein gene polymorphism in najdi cattle of iran. we used the polymerase chain r...

identification of associated genes with energy balance, yield and feed intake are recent interests of the animal breeding researchers. najdi breed is the famous cattle breed in the khuzestan province. in this research for the investigation of leptin gene promoter ,from 15 najdi cows in the shushtar cattle center station was taken. dna from whole blood was extracted and 544bp and 566 bp two piec...

ABSTRACT: Transmissible spongiform encephalopathies are neurodegenerative diseases that affect several mammalian species. Bovine spongiform encephalopathy (BSE) is among the mentioned diseases in cattle caused by abnormally fold prion proteins. Polymorphisms of the prion protein gene (PRNP) have been shown to be major determinations for the susceptibility to transmitted perion diseases in human...

the aim of the current study is to amplification the regularity region encompassed the mutations changing the myostatin gene express and also to determine sequential analysis. the blood samples taken from 12 najdi cattles in najdi cattle station in shushtar city, khuzestan province. then the dna extracted to amplification 730bp and 561bp fragments. sequencing was performed after the precision i...
