Who is Smarter? Sheep or Goats?

A new study investigated how well sheep and goats were able to navigate around obstacles to reach food.  The conclusion?  When it comes to adapting to new situations, goats are a step ahead. Compared to sheep, goats can more quickly adapt to changing environmental conditions.


Sheep and goats have many things in common: They are closely related genetically, roughly the same size, have similar social structures, and have both been domesticated by humans over approximately the same amount of time. They do, however, differ greatly when it comes to their foraging strategies.

“While sheep are grazers, goats are browsers and prefer buds and fresh shoots.”

Study overview

The team wanted to investigate how both animal species react to new spatial obstacles. The experimental set-up of the study was rather straightforward: one animal at a time was led to the end of a small enclosure. Another person stood at the opposite end offering food. In between was a fence with a gap — the direct path was blocked each time. The researchers observed the animals’ behavior, specifically, whether they moved directly towards the gap, and recorded the time it took them to reach the food. After a few rounds, the position of the gap in the fence was changed. The animals then repeated the test. A total of 21 goats and 28 sheep completed the experiment.

Results overview

In the first round with the newly located gap, the goats managed to walk around the obstacle easier and faster, although the sheep reached their goal faster on average. Both the sheep and goats were initially puzzled by the new position of the gap and needed a few attempts to adjust to the new situation. Afterwards, they made fewer mistakes. The experiments could not be carried out under identical conditions at both locations, but the results were nevertheless clear:

“Goats appear to adapt better and more accurately to new situations and move with less perseveration around the obstacle when the gap has changed. This suggests that they are more cognitively flexible than sheep.”

Why the difference?  Researchers say that one possible reason for the differences could be their different foraging strategies.
