Domesticated animals are those animals which have been domesticated by humans for various purposes or uses. For example, cows and buffaloes are domesticated by a large population in the world for purposes like milking etc.
But not all countries domesticate the similar kinds of animals. While some might domesticate chicken more than others, some may domesticate goats or cows etc. at some places, the number of domesticated animals is so large that it may exceed millions.
For example, China has the maximum population of domesticated chicken. Here the population of chicken is about 3 billion. The largest cow population in the world is in India as India has about 1.5 Billion cows.
China is also the home to the largest population of pig as it has got about 459 billion pigs. At 130 billion, China also has the largest population of sheep in the entire world. The largest population of cats is in USA and it has got about 76.4 billion cats.
When it comes to dogs, it is USA again with the maximum number of dogs. USA is home to about 70 billion dogs which is more than at any other place. Somalia is the place where the largest population of Camels is found.
