Why in News

  • Scientists from ICAR's National Research Centre on Yak (NRC-Y) and Assam Don Bosco University have developed a new technology.
  • They created an Internet of Things (IoT)-based smart collar system for high-altitude Himalayan yaks.

About the Himalayan Yak

  • The Domestic Yak, scientifically named Bos grunniens, is known as the Ship of the Himalayas.
  • This heavily built, long-haired animal is a vital resource for mountain communities.
  • Yaks provide essential resources like milk, meat, fiber, and fuel.
  • They also help transport heavy loads in tough mountain terrains.
  • These animals live in cold, high-altitude alpine zones above 8,000 feet and up to 18,000 feet across the trans-Himalayan region.
  • India has around 58,000 yaks according to the 20th Livestock Census.
  • Almost half of this population lives in Ladakh.
  • The remaining yak population is spread across the high-altitude areas of Arunachal Pradesh, Sikkim, Himachal Pradesh, and Uttarakhand.
  • The IUCN Red List classifies the wild yak as Vulnerable (VU).

Key Physical and Physiological Characteristics

  • Yaks have a thick outer coat and a dense woolly undercoat.
  • This dual-layer system helps them survive extreme cold down to -40°C.
  • Their coats secrete natural oils that repel water, keeping their skin dry during heavy snow, rain, and storms.
  • Their broad, split hooves give them a strong grip on rocky, icy, and snowy paths.
  • Yaks have larger chests, hearts, and lungs compared to other cattle, helping them breathe easily in low-oxygen areas.
  • Their blood has a high concentration of large red blood cells and specialized haemoglobin, allowing their bodies to carry oxygen efficiently.
  • Yaks cannot tolerate warm weather and experience severe heat stress when temperatures rise above 15°C.

Social and Behavioral Traits

  • Yaks live in groups led by experienced female yaks.
  • Adult male yaks usually live alone or form small groups.
  • Yaks are generally quiet animals.
  • They protect their calves from predators like snow leopards by forming a defensive circle.

Significance of Yaks

  • Yaks are crucial for the survival of Himalayan communities.
  • They provide food and income in areas where normal farming is impossible.
  • Their strength and ability to walk on difficult paths make them perfect for carrying goods across high mountain passes.
