The banteng (Bos javanicus) is a species of wild cattle native to Southeast Asia, including Java, Borneo, and the mainland. Bulls are dark and muscular, while cows and young are reddish-brown, and both sexes show a white rump patch and white lower legs. It grazes in forests and clearings and is the ancestor of domesticated Bali cattle.

Banteng live in structured social groups that vary by sex and age. Female-led herds typically consist of 5‑20 individuals, including calves and sub‑adult females, and maintain stable home ranges of 2‑5 km² where they graze and browse together. Mature bulls are either solitary or form small bachelor groups of 2‑4 males, defending territories that overlap with female herds during the breeding season. The species is diurnal, with peak activity at dawn and dusk when they move to fresh grazing sites. Communication relies on a repertoire of low‑frequency grunts, snorts, and a distinctive bellow during rut, as well as visual signals such as horn displays and scent marking from pre‑orbital glands. Seasonal migrations are limited, but groups may shift to higher ground during the rainy season to avoid flooding.

Banteng are strict herbivores, classified as mixed grazers and browsers. Their diet consists primarily of grasses (30‑40% of intake), supplemented by leaves, shoots, fruits, and aquatic plants during the wet season. In forested habitats they browse on young foliage of dipterocarp trees, while in open savanna they favor tall grasses such as Imperata cylindrica. Daily food intake averages 2‑3% of body weight, equating to 10‑15 kg for an adult bull. They feed in groups, often moving in a loose formation to maximize grazing efficiency and reduce parasite load. Seasonal variations in food availability drive shifts in foraging behavior; during the dry season they may travel longer distances to reach water sources and high‑quality forage. Their digestive system, a ruminant fore‑stomach with four chambers, allows efficient extraction of nutrients from fibrous plant material.

Sexual maturity is reached at 2‑3 years for females and 3‑4 years for males, though successful breeding by bulls often depends on dominance status. Banteng breed year‑round, with a slight peak in the dry season (December‑February) when food is abundant. The gestation period lasts approximately 285 days, resulting in the birth of a single calf weighing 25‑30 kg. Calving intervals average 18‑24 months, and females exhibit strong maternal care, nursing for 6‑8 months while the calf remains hidden in dense vegetation for the first few weeks. Juveniles stay with the natal herd until they reach sexual maturity, at which point males may disperse to form bachelor groups or become solitary. Parental investment is high, with mothers defending calves from predators such as leopards and large snakes.

The IUCN classifies the banteng as Endangered, with an estimated 9,000‑10,000 mature individuals remaining in the wild—a decline of over 50% in the past three generations. Primary threats include illegal hunting for meat, hide, and horns, which are prized in traditional medicine and as trophies. Habitat conversion to oil palm plantations, rice paddies, and infrastructure development fragments populations and reduces available grazing land. Hybridisation with domestic cattle poses a genetic threat, diluting the species’ unique gene pool. Additionally, disease transmission from livestock, such as bovine tuberculosis, further endangers wild herds. Conservation actions involve expanding and effectively managing protected areas, implementing community‑based anti‑poaching patrols, and maintaining captive‑breeding programs that aim to re‑introduce pure‑bred individuals. International trade of banteng parts is prohibited under CITES Appendix I, providing legal reinforcement to protection efforts.
