Water Buffalo

== Description ==
The Water buffalo (Bubalus bubalis) is a large bovid from the Indian subcontinent and Southeast Asia. Today, it is also found in Europe, Australia, North America, South America, and some African countries. Two extant types of water buffalo are recognized, based on morphological and behavioral criteria: the river buffalo and the swamp buffalo. The wild water buffalo (Bubalus arnee ) most likely represents the ancestor of the domestic water buffalo. These animals are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. A large feral population became established in northern Australia in the late 19th century, and there are smaller feral herds in Papua New Guinea, Tunisia and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Colombia, Guyana, Suriname, Brazil, and Uruguay.
== Appearance ==
The skin of River buffalo is black, but some specimens may have dark, slate-colored skin. Swamp buffalo have grey skin at birth but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; their body is short and their belly is large. The forehead is flat, the eyes are prominent, the face is short, and the muzzle is wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks.
== Distribution ==
Water buffalo originate in the Indian subcontinent, Southeast Asia, and China. Today, they are also found in Europe, Australia, North America, South America, and some African countries. River buffalo occur in the Indian subcontinent and further west to the Balkans, Egypt, and Italy, and Swamp buffalo are found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. Water buffalo inhabit tropical forests and wet grasslands, riverine forests, marshes, and swamps. As their name suggests they require an environment with adequate water for wallowing and drinking. Some breeds are adapted to saline seaside shores and saline sandy terrain.
== Lifestyle ==
Water buffalo are terrestrial animals but are very dependent on water. They spend most of their time wallowing in rivers or mud holes. River buffalo prefer deep water while Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud that protects the buffalo skin from sunburn and biting insects and also keeps them cool. Water buffalo are social and live in herds of up to 30 individuals. Herds usually consist of adult females, their calves, and sub-adult females. Young males leave female herds when they are around 3 years old and form bachelor herds. Water buffalo are both diurnal and nocturnal. They usually feed in the morning and evening. During the midday heat, they rest in the shade, wallow in mud holes, or stay submerged in water with only their nostrils and eyes exposed. During floods, they graze submerged, raising their heads above the water and carrying quantities of edible plants. Water buffalo communicate with each other with the help of snorts and grunts. Males also stamp on the ground to show dominance or as a means of defense.
== Diet ==
Water buffalo are herbivores. They feed on aquatic plants, grasses, reeds, herbs, leaves, and other vegetation.
== Reproduction ==
Water buffalo have a polygynous mating system in which males breed with more than one female. They generally breed year-round. Females usually give birth to a single calf every two years. The gestation period lasts 300-320 days. Calves are born red to brown in color and weigh 35 to 40 kg. Females protect and nurse their calves from 6 to 9 months. At the age of 3 young males become reproductively mature and disperse. Young females remain in the herd where they were born and reach reproductive maturity when they are 1,5 years old.
== Population ==
=== Population number ===
According to Wikipedia resource, the total population of Water buffalo in 2011 was about 172 million individuals.
=== Ecological niche ===
Water buffalo have a herbivorous diet and feed on various vegetation. Some of these plants are of great value to local people but others are a major problem in some tropical valleys and Water buffalo may help to keep waterways clear.
== Domestication ==
Water buffalo were domesticated in the Indian subcontinent about 5000 years ago, and in China about 4000 years ago. At least 130 million domestic water buffalo exist, and more people depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The husbandry system of Water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in close association with them and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. Their dung is used as fertilizer, and as fuel when dried. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
