Miniature Zebu at the Hagenbeck Zoo, Hamburg (Germany)

The Miniature Zebu or Dwarf Zebu, also known as Nadudana or Nadudana Zebu, are a unique and compact variation of the Zebu breed. They are considered a miniature or dwarf subspecies. Despite their smaller size, they retain many characteristics of their larger Zebu relatives. Miniature Zebu cattle have distinct physical features, including their humped back and large, expressive eyes. The hump, similar to that of a camel, is composed of adipose tissue and functions as a valuable energy reserve during times of food scarcity and drought. This unique adaptation enables them to endure challenging conditions by utilizing the stored fat for sustenance. Predominantly, they are coloured gray, but can also be black, red, spotted, or white. In bulls, the neck, shoulders, and hump may also be black. These animals are slow to mature, but have very long lifespans, an average of 18 to 21 years.

The Hagenbeck Zoo (Tierpark Hagenbeck) is a zoo in Stellingen, Hamburg, Germany. The collection began in 1863 with animals that belonged to Carl Hagenbeck Sr. (1810–1887), a fishmonger who became an amateur animal collector. The park itself was founded by Carl Hagenbeck Jr. (1844–1913) in 1907 and it is still operated and owned by the Hagenbeck family today. It is known for being the first zoo to use open enclosures surrounded by moats, rather than barred cages, to better approximate animals' natural environments. Over the years, the zoo has gained a good reputation for successfully breeding rare and endangered species such as the Asian Elephant and the Siberian Tiger.
