Water buffaloes ( Bubalus bubalis ) only have A2A2 genotype for beta-casein

This study aimed to evaluate the alleles of beta-casein in buffaloes. A total of 657 buffaloes of four different breeds were genotyped and all animals carried the A2A2 genotype, i.e., allele A1 does not exist in the buffalo species. Thus, all milk products of buffaloes are naturally A2. This result adds value to products derived from buffalo milk.
