I honestly think this study is crock... their causality is illogical, for example. "Cooling"?? It would be cooler to face east/west than north-south; less surface area directly in the sun (on average over all seasons). In the summer specifically (in areas where only summer is hot), facing northeast/southwest (or, in general, facing the sun directly) makes the most sense.
It sounds to me like a 'study' that was easy to publish and solid enough to pass first muster (peer review), but is really meaningless; it's far more likely correlation, something like "people usually make hills face a certain way, and that causes cows to go north/south", or something else. |

It's pretty easy actually to figure out where north is if you can see the sun. If you face the sun at noon, you will be facing due south in the northern hemisphere above the tropics, and due north in the southern hemisphere, below the tropics.
If it's before noon, the sun will be SE, if it's after noon, the sun will be SW. It's a bit more complicated in the tropics, but the same idea is there. If you can figure out an arc, you can even tell time with the sun. |

There might be an easier explanation other then cows can read the earth's magnetic field. Maybe it is cold and the cows turn with their sides facing east-west so they get the most sun or maybe the wind is blowing from the south so facing north gets their faces out of the wind and provides the smallest wind profile.
