Livestock Carrier is a special type of ship particularly made for transportation of animals, specifically livestock such as cows, sheep, goats etc. Livestock carriers are nothing but container carriers modified in their design and construction, in order to carry animals. All the import and exports of animals are done strictly in accordance with international legislation. Cattle and sheep are the two main types of animals that are transported in millions, around the world. Other then that, horses, deers, camels and few types of birds are also transported. There are specific carriers that carry live fish for fish farming purpose.
The size of these carriers varies, according to the type of livestock and market demand. Generally, they fall in the range of 2000 to 2500 Dead Weight Tonnage. Also, the number of crew members on livestock carrier are more than that on any other carrier. Experienced stock men are hired in order to look after the livestock. The number of stock men on board a ship depends on the number of livestock pens and the kind of automation provided on ship.
In short, extra care is needed for transporting livestock. This doesn't mean just human assistance but also the design and ambient environment on the ship.
Also, the construction of the ship is slender in order to prevent rolling and pitching. This helps to prevent animals from breaking their legs when the ship experiences excessive movement.
