Scientific classification, so that species belonging to the same genus (group of closely related species) can be called kangaroo, wallabies or walaru, only depending on their size. For example, Macropus parma wallabies is known as the Parma, while Macropus antilopinus is known variously as walaru antelope antelope or kangaroo.

Macropodinae subfamily also includes species of kangaroos, and walarús walabís, other commonly known as tree kangaroos, Cuoco, and pademelones dorcopsis.

There are many so-called kangaroo species, and this is reflected three of them:

* The red kangaroo (Macropus rufus), which is the largest of the kangaroos and the largest of the marsupials still in existence. Red Kangaroos occupy the arid and semi-central arid Australia. An adult male can measure 1.5 m in height and weigh 85 kg.
* The eastern gray kangaroo (Macropus giganteus), less known than the red kangaroo, but most frequently sighted, as its range covers the fertile eastern area of ​​Australia.
* The western gray kangaroo (Macropus fuliginosus), of smaller size and found south of Western Australia, South Australia near the coast and the Darling River basin.

Kangaroos have large powerful hind legs, large feet designed to jump, long, muscular tail for balance and a small head. Kangaroos are herbivores, eating grass and roots. All species are nocturnal and crepuscular, usually spending the day quietly and feeding in the afternoons and cold nights, usually in groups. They have a life expectancy of 18 years ago.

Kangaroos are found mostly in Oceania. Popularly known as the kangaroo is the animal most representative of Australia.

Origin of name

The word kangaroo derives from gangurru, a word of Guugu Yimidhirr (an Australian Aboriginal language), referring to the gray kangaroo. The name was first written (in English kangaroo by Lieutenant (later Captain) James Cook) on August 4, 1770.

A widespread legend says that in fact the name kangaroo would come to ask the West the name of that animal and this be what the natives responded, and their meaning but would not be the name of the animal, but simply saying “do not understand their question

Reproduction

Reproduction is sexual and varies greatly with species. The red kangaroo is an opportunistic player, as they mate and reproduce when seasonal conditions are favorable for breeding of offspring. Grey Kangaroos breed all year round, but young calve in the summer months, as they leave the bag on the ideal time the spring. Other species have more restricted breeding season.

The courtship may last a few hours or extended 2 or 3 days. The male follows the female is in heat, often sniffing the urogenital opening of the bag and playing the female tail with his paw. The male makes wallabies characteristic sinuous lateral movements and with the tail, which produce clicks, the matching can be shorter or longer than one hour, as in the case of gray kangaroo.

In many species, such as Cuoco, mating takes place after birth (post partum estrus), but in these cases usually occur at rest a blastocyst, which develops later, when the previous birth rearing leave the pouch. The young are born between 28 and 36 days of mating. Remain in the bag about 8 months, but continue to nurse her back to about six months, at which time and another calf will be born. Young people often interact with their mothers until they reach sexual maturity.

The buffalo is a domestic ruminant, gregarious, semi-aquatic, gentle, curious, nocturnal, delicate and sensitive temperament, quiet and calm. His affinity with humans is in the same range of dog, horse and sheep. Symbol of life, religion and longevity.

Its color is gray, blackish, or black, the sides are red and the bottom of the coat is black.

Background

Buffalo is no stranger to man and his friendship comes from the origins of both. The Bubalus bubalis, or water buffalo has its origins in Asia (Asian humid equatorial tropics), the cradle of human culture, and were domesticated about 4,500 years BC They were first taken to Africa, then Europe, Oceania and finally to America, therefore, the buffalo are found in all corners of the earth.

In the course of evolution some herbivores have specialized career and flee from predators due to its speed. Others are full-bodied and equipped with powerful defenses with which lash the carnivores.

One animal of this group known for such behavior is the buffalo.

It was introduced in Venezuela in 1920 by then-dictator Juan Vicente Gómez. Disappear in the 40′s, and until 1962, where important characters of this animal zoos. In 1967, firm initiated the first steps of the national breeding stock. In the 90′s is when it began commercial scale.

Applications

Milk production: The buffalo is the second species in milk production worldwide. Currently in Venezuela there are very few buffaloes herds involved in this production. Buffalo milk contains a higher percentage of fat, from 5 to 9%, compared with cattle that have a range of 3 to 4%. The total solids ranging from 14 to 19%. The protein is located in the order of 4.5%. One liter of buffalo milk is equivalent to 1.7 liters of cow milk. For 1 pound of butter for example, it takes 14 liters of cow’s milk or 10 liters of buffalo milk.

Meat Buffalo meat well fed young animals is juicy, tender, tender and very palatable. Color is darker than the vaccine with the highest percentage of minerals. The animals reached 480 kg at 24 months of age. Buffalo leather is more resistant than cattle, being able to get higher quality items as well as having more layers of fodder for making gloves, shoes, etc.

Scientific classification

The buffalo belongs to the subfamily of Cattle, within the family Bovidae, which in turn is included in the order Artiodactyla. Asian buffalo scientist called Bubalus bubalis Bubalus the tamarau the mindorensis. The anoa are classified as Anoa anoa and Anoa depressicornis. Cape buffalo are classified under the scientific name Syncerus caffer caffer, and wild dwarf buffalo Syncerus caffer nanus on.
