ONE of the smallest hoofed animals in the world, a rare mouse deer, has been born at a Hampshire zoo. 

Staff at Marwell Zoo in Colden Common have welcomed the tiny youngster that was born to parents, Gus and Gwen at Marwell's zoo's Energy for Life: Tropical House. 

The Javan Chevrotain, also known as a mouse deer, weighed approximately 370 grams at birth and keepers say the new arrival is doing well, though their interactions are minimal due to the sensitivity of the species. 

In the wild, the nocturnal species is found on the island of Java in Indonesia and are hunted and traded both as pets and as wild meat.

When born, the young are the size of a rat and can run and jump soon after birth. They suckle only occasionally, and only at night.

Tim Rowlands, Marwell Zoo’s Hoofstock Team Leader, said: “We separated the male and female two weeks before she gave birth so she would not be disturbed, even by him, mimicking the natural behaviour of the female taking herself away to find a quiet and secure spot to give birth in the wild.

"All deer species will hide their young until they are older so they will only really come out to feed then hide again.

“There are very few zoos who care for any of the mouse deer species as they are so small in size, very secretive, and nocturnal, so any youngster born is great news for the conservation breeding programme.

"It’s vitally important that we work to ensure these wonderful animals do not disappear for good.”

The species is classified as data deficient, partly because there is a lack of information about how many species of chevrotain there are on Java.
