The blood DNA extraction was performedaccording to the protocols proposed by Yves Amigues and genotyping protocols was proposed byLeifers and Pomp et al. The body weight is within standards. The analyzed protocols used for leptinegene emphasizing led to satisfactory results, which will enable us to perform further research in orderto make associations between this possible marker gene and some body traits. %K leptine %K cattle %K traits %K meat %U http://usab-tm.ro/fileadmin/fzb/PDF%202008/Volumul%201/Biotechnologies/Carsai-1.pdf
