The correct answer is: c) Free-range grazing.
Traditional livestock rearing in Mizoram often depends on free-range grazing. This is because the state has a large area of hilly terrain that is suitable for grazing. The livestock are allowed to roam freely in the hills, where they find their own food and water. This system of livestock rearing is sustainable and environmentally friendly.
Intensive feedlots are large, enclosed areas where livestock are kept in close confinement and fed a high-energy diet. This system of livestock rearing is often used in developed countries, where there is a high demand for meat. However, it is not sustainable in the long term, as it requires a lot of land and water.
Factory farming is a type of intensive livestock farming where animals are kept in very close confinement and are not allowed to roam freely. This system of livestock farming is often used to produce meat and eggs at a low cost. However, it is considered to be cruel to animals and is not sustainable in the long term.
Specialized veterinary care is the provision of medical care to animals by a veterinarian. This type of care is often necessary for animals that are sick or injured. However, it is not always affordable for farmers in developing countries.
In conclusion, traditional livestock rearing in Mizoram often depends on free-range grazing. This is because the state has a large area of hilly terrain that is suitable for grazing. The livestock are allowed to roam freely in the hills, where they find their own food and water. This system of livestock rearing is sustainable and environmentally friendly.
