Yes Matt, that is the milking strain commonly found in Western India and a few other regions. I understand that a Texas heard has been established with animals from the Phillipines (John Barsness of Rifle & Handloader magazine & Charlie Sisk the rifle maker hunted them a few years ago).

The scientific data is probably slim because the wild buffalo started declining even in the early 1900's - flood plains & marshes were the first areas to be encroached upon by villagers for cultivation. Loss of habitat - same old story. According to IUCN the term "Bubalus Bubalis" was coined for the domestic buffalo & that some authorities use the name "arnee" for the the wild species.

BTW - Can I send you a PM about hunting buffalo in OZ? Cheers
