Researchers Managed to Toilet Train Cows, and They Learned Faster Than a Toddler

We managed to toilet train cows, and they learned faster than a toddler:

Cattle urine is high in nitrogen, and this contributes to a range of environmental problems.

[...] Behavioural psychology tells us a behaviour is likely to be repeated if followed by a reward, or "reinforcer". That's how we train a dog to come when called.

So if we want to encourage a particular behaviour, such as urinating in a particular place, we should reinforce that behaviour. For our project we applied this idea in much the same way as for toilet training children, using a procedure called "backward chaining".

First, the calves were confined to the toilet area, a latrine pen, and reinforced with a preferred treat when they urinated. This established the pen as an ideal place to urinate.

The calves were then placed in an alley outside the pen, and once again reinforced for entering the pen and urinating there. If urination began in the alley, it was discouraged by a mildly unpleasant spray of water.
