Introduction

Bos is a genus of bovines encompassing both wild and domestic cattle. Traditionally, the genus comprises five living species, but this number increases to eight if domesticated forms are treated as distinct species, and can reach ten when including the closely related Bison.

Description of Bos

Bos species are primarily grazers, equipped with large teeth to efficiently process the plant material they consume. They are ruminants, possessing a four-chambered stomach that enables them to break down tough vegetation.

Today, there are roughly 1.3 billion domestic cattle, making them among the most numerous mammals worldwide. Members of this genus are distributed across Africa, Asia, Europe, America, and Oceania, inhabiting a wide range of environments, from prairies and savannahs to rainforests, wetlands, and temperate forests, depending on the species.

In the wild, most Bos species live for 18–25 years, although individuals in captivity can reach up to 36 years. They experience a gestation period of about 9–11 months, giving birth to one, occasionally two calves, usually in the spring. Bos animals typically form small herds of 10–30 individuals, often structured around a single bull with multiple cows. Dominance within the herd plays a key role, with calves often inheriting their mother’s position in the social hierarchy.

Their daily activity patterns are mostly diurnal, with rest during the hottest part of the day and activity in the morning and afternoon. Certain species also display migratory behavior, moving according to the availability of food and water.
