Smiles....This actually sounds funny though but isn't it natural for you to love what you own and rear? The Fulani nomads are known for their grazing and rearing of livestocks such as cows either for consumption or commercial activity (business). They go around with their flock of cows feeding them by making them eat grasses and drink water before returning back home.
It is very natural they love their livestock because you actually get attached to animals or people you are a mates around with. If any bad thing happens to any of their cow, it might be a great loss for them since it will affect their business productivity and earnings.
You know they actually brought up those big cows walking around with them right from their early stage till they grow up and become very big and mature to sell when it's time. They also spend lots of money and time feeding them just to make them grow bigger and mature.. Why won't you expect them to love their livestock if they had to go through such strenuous activities?
Thanks for reading and I hope this helps.
