The gaur (Bos gaurus), also known as the Indian bison, is the largest living species in the bovid family, which includes all wild and domestic cattle. Adult males can weigh up to 1,500 kg and stand nearly 200 cm tall at the shoulder. It is native to the Indian subcontinent and Southeast Asia.
The global population was estimated at a maximum of 21,000 mature individuals in 2016, with the majority living in India. The IUCN has listed the gaur as Vulnerable since 1986. Populations in Indochina and Malaysia declined by more than 70 percent over the last three generations of 24-30 years.
Gaur are found in India, Nepal, Bhutan, Bangladesh, Myanmar, Thailand, Laos, Cambodia, Vietnam and China. The species is regionally extinct in Peninsular Malaysia and Sri Lanka. The Western Ghats of southern India, including Nagarhole and Bandipur National Parks, hold some of the largest remaining populations.
Only tigers and saltwater crocodiles have been documented killing healthy adult gaur. Leopards, dhole packs and large mugger crocodiles occasionally take calves or sick animals. A saltwater crocodile would likely need to exceed 3.7 m in length and 300 kg in weight to attempt a healthy adult.
The first cloned gaur was born on the 8th of January 2001 at Trans Ova Genetics in Sioux Center, Iowa. It was carried to term by a surrogate domestic cow. The calf appeared healthy at birth but died within 48 hours from a common dysentery, most likely unrelated to the cloning procedure.
The gaur feeds on grasses, leaves, fruits, and bark from at least 32 plant species observed in one sanctuary study. In winter and the monsoon season it favors fine grasses and legumes such as tick clover. In summer it turns to teak bark and cashew fruit and bark as green vegetation dries up. Teak bark contains 22,400 ppm of calcium, which helps meet the animal's mineral needs.
