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 pieces of was used for amplification. After ensuring the correctness PCR products on agarose gel 1% sequences gene was performed and component promoter leptin was found in Najdi cow. In the first fragment(566bp) of the study was recognized, 6 Mutation, two point mutations one of the transition and the other was transversion and four frameshift mutations that mutations of another typ of, deletion and insertion. In the second segment(544bp( was observed in the leptin gene promoter region two point mutations one of the transition and the other was transversion and deletion of a frameshift Mutation The results of this study showed that reports Mutations on boxes and component promoter did not affect leptin gene.In this study was compared the sequence corresponding to a single on sample in terms of both pieces were registered on sequence similarity with other region that blast results showed a high percentage of similarity.
