Compared to a bull a bullock is docile because of:

1. higher levels of cortisone
2. lower levels of blood testosterone
3. lower levels of adrenaline/noradrenaline in its blood
4. higher levels of thyroxine.

Correct answer: lower levels of blood testosterone

Solution

Bullocks are typically castrated males, so they produce much less testosterone than bulls. Lower testosterone reduces aggressive and dominant behavior, making them more docile.
