Context: Indian scientists have achieved a breakthrough in yak genomic research by assembling the first-ever chromosome-level genome of the Indian yak (Bos grunniens).

• The initiative, led by ICAR-NRC on Yak, Dirang, will bolster breeding programs and improve conservation of this high-altitude livestock species.

About Indian Yak:

• What It Is:

• The Himalayan yak is a long-haired, high-altitude bovine species belonging to the Bovini tribe (includes cattle, buffalo, and bison). Scientifically known as Bos grunniens, it is revered as the ‘ship of the Himalayas’ for its transport and livelihood utility.

• Habitat & Distribution:

• Endemic to the Tibetan Plateau and surrounding high-altitude zones. Comfortable at altitudes above 14,000 feet. In India, yaks are reared in: Arunachal Pradesh, Sikkim, Uttarakhand, Himachal Pradesh, Jammu & Kashmir, and Ladakh.

• Key Features:

• Extreme Cold Resistance: Tolerates temperatures as low as –40°C. Adapted Physiology: Possesses an enlarged rumen to digest low-quality forage efficiently. Thick Coat: Long, hanging hair forms an insulating layer against cold winds. Transhumance Rearing: Traditionally managed under primitive nomadic systems. Lifeline of Nomads: Critical for milk, meat, wool, hide, dung fuel, and transport in Himalayan economies.

• Significance:

• Livelihood Security: Backbone of pastoral communities in eco-fragile zones. Genetic Resource: Offers traits like cold resilience and disease resistance, vital for climate-smart livestock breeding. Economic Importance: Supports eco-tourism, dairy cooperatives, and wool industry in hill economies. Ecological Role: Integral to maintaining grassland balance and pastoral sustainability in alpine meadows.
