For example, to start with an all young group of the same age, it’s not natural. And these animals will fight for dominance. This can last 10 years or longer. And this might be very severe for the sub dominant animals. So you have to start with a group with a natural age composition. A very old cow, a younger cow, a sub-adult cow, and a young calf, and then you have the natural group composition. We have to aim to reach this in every zoo. And then, of course, training of elephant.
