Genetic Polymorphisms Of The DNMT3b Gene In Local And Imported Calves

This study was conducted in the laboratories of Department Animal Production College Agriculture - University Basrah for period from 1/11/2021 to 1/5/2021. The data this were collected Dhi Qar Governorate included samples blood and meat. These taken 30 imported local (Jenoubi) calves aged (1 2) years. Ten ml as well 250 g meat thigh, shoulder back area ​​all animals. DNA extracted primer DNMT3b gene used (PCR) technique amplify gene. aim association DMNT3b polymorphism with sensory physical characteristics result amplification a size 611 bp three haplotypes obtained calves. 2nd haplotype differed 1st 3rd by nitrogen base 409, while 526. statistical analysis did not show significant differences distribution hot carcass weight significantly affected (P<0.05) calf breed calf’s (155.87 kg) exceeded those (131.71kg). also influenced different DNMT 3b gene, superiority types compared haplotype. saturated unsaturated fatty acids% calves’ where palmitic acid% superior than that (25.78, 26.61 24.69%, respectively). As total polyunsaturated acids, outperformed (48.23 44.9% acids 8.87 8.10%
