The river buffalo (Bubalus bubalis carabanensis) represents one of two distinct subspecies of water buffalo, distinguished from swamp buffalo by centuries of selective breeding for dairy production. While both subspecies share the scientific name Bubalus bubalis, the river type has been genetically differentiated through focused selection for milk yield, body conformation, and specific behavioral traits conducive to intensive dairy management.
The designation 'river buffalo' reflects their historical association with the great river systems of South Asia, particularly the Indus, Ganges, and Brahmaputra river valleys where these animals have been central to agricultural life for over 5000 years. Unlike their swamp buffalo cousins, which are primarily draft animals, river buffalo were developed as dual-purpose animals with emphasis on milk production, resulting in distinct physical and productive characteristics.
Several distinct breeds fall under the river buffalo classification, each developed in specific geographic regions. The Murrah from India's Haryana state is considered the premier dairy breed, renowned for heavy milk production and excellent butterfat content. Mediterranean buffalo, introduced to Italy centuries ago, produce the authentic milk for traditional mozzarella di bufala. The Nili-Ravi of Pakistan, Jaffarabadi of Gujarat, and Egyptian buffalo represent other important river-type breeds, each adapted to their regional environments while maintaining the fundamental dairy-focused characteristics.
Terminology can be confusing, as these animals are often simply called 'water buffalo' or 'Asian buffalo' in common usage, terms that technically encompass both river and swamp types. In dairy contexts, they're frequently referred to as 'dairy buffalo' or 'milk buffalo' to distinguish their primary purpose. Scientific and agricultural literature maintains the river buffalo designation to differentiate them from the swamp type at the subspecies level, a distinction crucial for breeding programs and agricultural planning.
