The gayal (Bos frontalis), also known as mithun, is a large semi-domesticated bovine distributed in north-eastern India, Bangladesh, northern Myanmar and in the Yunnan Province of China.[1]

In the Adi language, gayal are called eso; they are called subu by the Apatani and Nyishi tribes, or often referred to as "mithun".

Characteristics[edit]

The gayal differs in several important particulars from the gaur. It is somewhat smaller, with proportionately shorter limbs, and stands much lower at the withers. The ridge on the back is less developed, and bulls have a larger dewlap on the throat. The head is shorter and broader, with a perfectly flat forehead and a straight line between the bases of the horns. The thick and massive horns are less flattened and much less curved than in the gaur, extending almost directly outwards from the sides of the head, and curving somewhat upwards at the tips, but without any inward inclination. Their extremities are thus much farther apart than in the gaur. The female gayal is much smaller than the bull, and has scarcely any dewlap on the throat. The skin colour of the head and body is blackish-brown in both sexes, and the lower portion of the limbs are white or yellowish. The horns are of uniform blackish tint from base to tip. Some domesticated gayals are parti-coloured, while others are completely white.[2]

Distribution and habitat[edit]

Gayals are essentially inhabitants of hill-forests. In India, semi-domesticated gayals are kept by several ethnic groups living in the hills of Tripura, Mizoram, Assam and Arunachal Pradesh. They also occur in the Chittagong Hill Tracts.[2] In northern Myanmar, they occur in the Kachin State, and in the adjacent Yunnan Province are found only in the Dulong and Nujiang River basins.[1]

Taxonomy[edit]

In his first description of 1804, Aylmer Bourke Lambert applied the binomial Bos frontalis to a domestic specimen probably from Chittagong.[3]

In 2003, the International Commission on Zoological Nomenclature fixed the first available specific name based on a wild population that the name for this wild species is valid by virtue of its being antedated by a name based on a domestic form. Most authors have adopted the binomial Bos frontalis for the domestic species as valid for the taxon.[4]

Phylogenetic analysis corroborates the taxonomic assessment that the gayal is an independent Bos species originating matrilineally from Bos gaurus, Bos indicus and Bos taurus.[5]

In culture[edit]

To the Adi people (Bangni-Bokar Lhobas), the possession of gayal is the traditional measure of a family's wealth. Gayal are not milked or put to work but given supplementary care while grazing in the woods, until they are ritually slaughtered or killed for local consumption.

The gayal is the state animal of Arunachal Pradesh and Nagaland. Gayals play an important role in the social life of the people in Arunachal Pradesh. Marriages are not fixed until the bridegroom's family gives at least one gayal to the bride's household.[citation needed]

Gayals are left in the forest, where they usually stay within a small perimeter. Females are usually aggressive when with calves, and there are instances known when people have been severely injured after being gored by one. Male are usually more docile.[citation needed]
