beta-lactoglobulin (lgb) is one of the proteins in the mammals’ milk synthesized by the epithelial cells of the mammary glands and affects the quality and coagulation of the milk. the aim of this study was to determine allele frequencies in lgb gene of native and holstein cattle in kerman province using pcr-rflp method. genetic polymorphism, for 100 dna samples in the locus was determined by di...

the poly morphism of 4 micro satellite loci (bms1350, lgb, ilsts45, bms1915) associated with functional traits were evaluated for detecting the diversity level in baluchi breed of sheep. one hundred eighty five blood samples were collected from sheep herd in abbas-abad breeding station. dna extraction was performed using guanidinethiocyanate silica gel method. gene fragments of micro satellites...

This investigation aimed to study polymorphism of growth hormone (GH), growth hormone receptor (GHR), and insulin like growth factor 1 (IGF-1) genes and their associations with growth and carcass traits in Mazandaran native chicken. 200 male chicks were reared and slaughtered at 12 weeks of age. Traits including live weight at 4, 8 and 12 weeks of age, body weight and weights of heart, liver, g...

Four Saudi Arabian indigenous sheep populations including Najdi, Hbsi, Arb, and Naemi were genotyped for 16 microsatellite markers recommended by the food and agriculture organization (FAO). This study aims to provide information on the genetic structure of the breeds analyzed and give indications and proposals for the cross breeding program. All loci were polymorphic in all populations and loc...

calpastatin (cast) is a specific inhibiter of calpains, playing a role in meat tenderization and myogenesis. in the present study, the polymorphism of the cast gene of makoei sheep was investigated by polymerase chain reaction and single strand conformation polymorphism technique (pcr–sscp). genomic dna was extracted from whole blood samples collected from 100 sheep. a 622 bp cast exon 1 segmen...
