Luit (swamp) buffalo

Luit is India's only registered swamp-type buffalo (Bubalus bubalis carabanesis), distinct from the river-type buffaloes that dominate the Indian dairy industry. Registered with NBAGR in 2014, the breed is native to the floodplain and char-land ecosystems of the Brahmaputra valley in Assam. Swamp buffaloes have 48 chromosomes (versus 50 in river buffalo) and a different productivity profile — slow maturing, low-milk but extremely strong for draught and wallowing.

Origin and distribution

The home tract is the Brahmaputra valley districts of Assam — Lakhimpur, Dhemaji, Sonitpur, Darrang, Morigaon, Nagaon, Kamrup and Goalpara — extending into adjoining parts of Arunachal Pradesh and Nagaland. The breed shares a genetic background with swamp buffaloes of Bhutan and northern Myanmar, and is the workhorse of jute, paddy and char-land farming in the lower Brahmaputra.

Morphology

Luit is medium-sized with a stockier, lower-slung body than river buffaloes. Adult cows weigh 350-400 kg and bulls 450-500 kg. Coat colour is slate-grey to dark grey, with a characteristic pale "chevron" mark on the neck and lower jaw. Horns sweep outward and slightly upward in a wide crescent — much flatter and more horizontal than Murrah. The hooves are notably broad with wide-splayed toes — an adaptation to mud and flood-plain grazing.

Productivity

Lactation yield is low at 400-700 kg over 250-280 days; milk fat is high at 8-9% and SNF 9.5%. The breed reaches first calving late (50-60 months) and calves every 18-24 months — too slow for commercial dairying but acceptable in subsistence systems.

Luit's real value is draught and wallowing performance. A pair can plough 0.3-0.4 ha of saturated paddy field per day, work in standing water and pull jute carts where wheels sink. Animals are also slaughtered for buffalo meat — a major protein source in Assam.

Management

Luit is a low-input breed: animals are released into char-land grazing during the day, brought back to night shelters, and given paddy straw and rice gruel only during heavy work. Wallowing in ponds or river channels is essential — without daily wallow, animals overheat and lose condition rapidly. Indiscriminate crossing with Murrah is genetically barred at the chromosome level (50 × 48 = sterile or low-fertility F1), so breed conservation through pure-breeding is the only viable improvement path. ICAR Research Complex for NEH Region, Umiam, runs the breed conservation programme.
