Concept:Pastoral farming is the branch of agriculture devoted to the rearing of livestock only, such as cattle, sheep, and goats.
Explanation:The key word in this question is "only animals".
Pastoral farming involves raising solely animals without combining it with crop cultivation.
It is commonly practised in the savanna belt of the north because the grassland vegetation provides natural pasture for grazing.
The Sudan savanna and other northern grass zones support the movement of herds, so cattle, sheep, and goats are frequently kept there.
Mixed farming would involve both crops and animals, while intensive farming relies on large inputs to boost output per hectare.
Therefore, the activity described exactly matches pastoral farming.
