Abstract

The association of genes polymorphism of DGAT1 and SCD1 has proved with milk nutritive value. The aim of the present study was the comparison of genetic structure of DGAT1 and SCD1 loci between HOLSTEIN and SIMMENTAL population.102 Mazandaran SIMMENTAL and HOLSTEIN cows were randomly selected and done blooding of neck vein. In digestion of SCD1 PCR products (725bp) with AluI enzyme, two alleles V and A were revealed with the frequency of 79 and 21 percent and 92 and 8 percent in HOLSTEIN and SIMMENTAL breeds, respectively. In digestion of the 325bp fragment of this gene with NcoI enzyme, two alleles of C and T were detected with the frequency of 40 and 60 percent and 45 and 55 percent in HOLSTEIN and SIMMENTAL breed, respectively. Two alleles of A and K were detected from amplification of DGAT1 locus with the frequency of 60 and 40 percent and 57 and 43 percent in HOLSTEIN and SIMMENTAL population, respectively. The result of statistical comparison of genotype and allele frequency in studied loci between two breeds indicates that DGAT1locus and second locus of SCD1 gene are same as gene frequency between two breeds and are different as genotype frequency in DGAT1 locus and are same as genotype frequency in SCD1 locus. According to observed polymorphisms, we can result that studied loci are fit for selection of animals with favorite genotype for increasing of production of milk useful fatty acids.
