Why Native Cows Matter for A2 Bilona Ghee?

Native Indian cows, known scientifically as Bos indicus, naturally produce A2 milk. This milk is the only suitable base for authentic A2 Bilona ghee. Without it, the process and the product fall short.

Rawat's Farm raises Rathi and Sahiwal cows in Rajasthan, two of India's finest native breeds. Every batch of our Indian desi cow ghee begins with their pure A2 milk.

The Genetics of Cow Breeds: A1 vs. A2 Protein

The difference between A1 and A2 milk comes down to a single amino acid in the beta-casein protein chain.

Native Indian cows carry Proline at position 67 of the beta-casein protein. This structural difference prevents the release of a peptide called beta-casomorphin-7 (BCM-7) during digestion.

Exotic breeds like Holstein and Jersey, classified as Bos taurus, carry Histidine at the same position. This allows BCM-7 to be released when digested, which research links to bloating, gut discomfort, and inflammatory responses.

A study published on PubMed Central confirmed through a randomised, double-blind, cross-over trial that consumers of A2 milk experienced significantly fewer symptoms of abdominal pain, bloating, and stool irregularity compared to those consuming A1/A2 blended milk.

Separately, genetic research by ICAR-NBAGR conducted allelic profiling across approximately 4,000 animals. It established that indigenous Indian breeds, including Sahiwal and Gir, carry the A2 beta-casein allele at a frequency of 94% to 98%, effectively making them natural A2 milk producers.

Rajasthan's Pride: Rathi and Sahiwal Breeds

Rajasthan has long been home to some of India's most resilient and productive native cattle. Two breeds, Rathi and Sahiwal, stand out for dairy quality. The Rathi cow is native to the arid belt of northern Rajasthan. It is known for:

● Strong heat tolerance suited to desert conditions.

● Good milk yields relative to its body size.

● Naturally high-fat content in milk.

● High A2 allele frequency confirmed in Bos indicus breeds.

The Sahiwal is one of the highest milk-producing native Indian breeds. Originating from the Punjab-Rajasthan region, it consistently yields milk rich in natural fat, protein, and the A2 beta-casein variant. It has long been used in pure desi dairy traditions.

At Rawat's Farm, we raise both breeds in their native Rajasthani environment, without hormone intervention, feedlot crowding, or artificial supplements. The result is milk that is naturally suited to the traditional Bilona method.

Native A2 Indian Cows vs. Exotic A1 Cows: A Comparison

The table below summarises the key differences between native Indian cow breeds and exotic breeds used in commercial dairy.

What Is The Role of Native Cow Milk in the Bilona Process?

The traditional Bilona method requires milk with the right fat structure, protein composition, and culturing behaviour. Native A2 milk delivers all three. The process works as follows:

● Fresh A2 milk is boiled and cooled.

● It is cultured with a live curd starter (dahi) to ferment overnight.

● The curd is hand-churned using a wooden churner (bilona) to separate butter (makkhan).

● The makkhan is slow-cooked over a low flame to produce clarified ghee.

Traditional milk culturing is where much of the nutritional value is built. Research on Indian dairy fermentation shows that culturing milk with traditional curd cultures allows Lactic Acid Bacteria (Lactobacillus species) to develop bioactive enzymes and natural probiotic colonies that are absent in raw or commercially processed milk.

The result is ghee that carries a far richer nutritional profile than commercially produced alternatives. This is the Bilona ghee process as it was practised for centuries, and it works best only when the milk comes from native A2 cows.

What Are The Health and Nutritional Benefits of Native A2 Bilona Ghee?

The combination of A2 milk and the Bilona method produces ghee with distinct health advantages.

1. Gut Health

A2 Bilona ghee is a significant source of Butyric Acid (butyrate), a short-chain fatty acid. 

Peer-reviewed research confirms that butyrate serves as the primary fuel source for colonocytes (cells lining the colon), repairs intestinal tight junctions, and suppresses pro-inflammatory cytokines. 

In simple terms, it helps maintain a healthy gut lining and reduces internal inflammation.

2. Heart Health

A2 Bilona ghee is rich in Conjugated Linoleic Acid (CLA) and medium-chain fatty acids. Lipid research on ghee's properties indicates that these compounds help balance blood lipid profiles and support HDL (good cholesterol) without inducing arterial oxidation when consumed in moderation.

3. Easier Digestion

Because A2 milk does not trigger BCM-7 release, the ghee made from it is gentler on the digestive system. Clinical findings confirm the molecular mechanism: the Proline at position 67 in A2 beta-casein resists enzymatic cleavage, preventing BCM-7 from entering the gut. The result is less bloating, less abdominal discomfort, and better tolerance for people who typically avoid dairy.

Pure Ghee From Rajasthan's Native Cows: Rawat's Farm

The quality of A2 Bilona ghee is inseparable from the breed that produces the milk. Native Indian cows, raised in their natural environment, are the only reliable source of genuine A2 milk.

At Rawat's Farm, our Rathi and Sahiwal cows graze freely in Rajasthan. The milk goes straight into the Bilona process.

If you want ghee that is traceable to the cow and backed by tradition, try our authentic A2 Bilona ghee. It is the clearest expression of what native desi cow dairy can offer.

Frequently Asked Questions

What makes native Indian cows better for A2 Bilona ghee than exotic breeds?

Native Indian cows (Bos indicus) carry the A2 beta-casein gene at a frequency of 94% to 98%, making them natural producers of pure A2 milk. 

Exotic breeds like Holstein and Jersey predominantly carry the A1 variant, which releases the BCM-7 peptide during digestion and is not suitable for authentic Bilona ghee.

Are Rathi and Sahiwal cows really A2 cows?

Yes. Both Rathi and Sahiwal are indigenous Bos indicus breeds, classified as A2 cattle by genetic research. 

Can people who are lactose intolerant consume A2 Bilona ghee?

Ghee contains negligible amounts of lactose, as it is removed during the clarification process. A2 Bilona ghee is further gentler on digestion because the A2 milk base does not trigger BCM-7 release, which is linked to the bloating and discomfort that many dairy-sensitive individuals experience.
