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.
