This study was conducted on a sample of Iraqi buffaloes to study the effect of genetic mutation in the Promoter region of the CYP 19 gene and its relationship to weight, total milk production and change in the proportions of milk components. It was also found that there was no significant effect of the mutation on body weight and total milk production. The mutation did not affect the proportions of milk components, except for the proportion of protein. The effect of the mutation on the proportion of protein without the rest of the studied traits shows the possibility of improving the proportion of protein in buffalo milk depending on the mutation recorded in the Promoter region of the CYP19 gene within the genetic selection programs and programs to improve the ability of local buffaloes to produce.
