Question: is buffalo milk a1 or a2?
Answer: Indian native breeds of cows and buffaloes are of A2 milk type and hence are a source for safe milk. The A1/A2 status of cattle is determined by the two alleles for beta-casein gene i.e. A1 and A2 and cattle may be homozygous for one type of protein (A1A1 or A2A2), or heterozygous (A1A2).
