Images from Google Earth have confirmed that cattle tend to align their bodies in a north-south direction. The scientists were unable to distinguish between the head and rear of the cattle, but could tell that the animals tended to face either north or south. Probably something to do with the earth’s magnetic field.
This magnetic field has been used to explain several things, from pigeons returning home to the underlying principles of Vaastu Shastra. Speaking of the latter, maybe cattle understand the fundas better than we do. I just checked up the site of a construction company which provides useful tips on Vaastu and it recommends that the occupants should face north or east while dining ( euphemism for grazing).
North or east? Some confusion here. The poles of the earth’s magnetic field cannot be at right angles to one another. Nor can the mouth and the rear of the person who is dining, unless he/she assumes a rather awkward position.
