Tigers are wild animals, and usually prosper at the top of the food chain of the original ecosystem. They use chasing methods to chase their food. In the wilderness, prey is usually large and covered with hooves, and in some cases it is high quality animals such as deer, antelope and even horses. The word "tiger" comes from Latin tigris. This means "Actaon's Spotted Tiger Hound" (Harper, 2014). This "big cat" belongs to the genus Pantella, and some researchers think that it comes from the old French word "pantail" meaning "yellow animals".
According to the International Tiger Research Report in 1994, about 490 Siberian tigers are managed at the zoo, including 226 in Europe, 151 in North America, 93 in Japan and 20 in Asian Zoos. The prisoners' population comes from the founder of 83 wild catchments. In most cases, Siberian tigers are considered safe for captivity. These animals are considered to be stable populations due to large genetic diversity gene pools. Siberian tigers are the heaviest subspecies and larger tigers weigh more than 500 or 225 kg. As with many other species, men are heavier than women. The lightest variant is Sumatra, these men weigh about 250 pounds or 110 kilograms, women weigh about 200 pounds or 90 kilograms. To get and maintain this weight, these cats have to eat a lot of food every day. Wild tigers can eat more than 60 pounds of meat in one place.
Zoos often use positive ways to help animal groups. To reduce seeds, many zoos propel breeding species and try to increase that number. After culturing a sufficient number of populations, animals can be released in the wild to promote the growth of the population. In this way, many animals including resident of famous zoo such as white tiger and panda have been greatly helped. The disadvantage of keeping animals in the zoo is the imprisonment they face. No matter how beautiful the zoo is, animals in the zoo are limited in space and are particularly troubling for large animals that are easy to walk around. Except for breeding under breeding and release of animals from other dangerous situations, taking out from animal habitat is a moral matter as it focuses on human interests rather than animal profits .
