Tag: Desi cows

Genetic studies confirm that a high percentage of indigenous Indian 'desi' cows, such as the Gir and Sahiwal breeds, possess the A2A2 gene variant, meaning they predominantly produce A2 milk. This contrasts with many modern Western dairy cows, which are known to produce milk containing a mix of A1 and A2 beta-casein proteins. The distinction has significant implications for digestive health, with many people finding Indian A2 milk easier to process.

While Western dairy cows often produce a mix of A1 and A2 beta-casein, indigenous Indian breeds like Gir and Sahiwal predominantly produce only A2 beta-casein. This critical protein difference influences how milk is digested and has sparked a nationwide debate about milk purity and health benefits.
