Domestic cows are a species called Bos taurus, from the Bovidae family and the Bovinae subfamily. They are common all over the world, in places with suitable areas for grazing. They are large animals, with a weight between 147 and 1363 kilograms, and a height between 49 and 52 inches.
Cows live in social groups called herds, led by a dominant male who also has exclusive rights to mating. Males tend to be larger than females, especially in the head and neck area. Both males and females may have horns, which are hollow in the middle. Cows mate year-round and their gestation period is nine months.
