A cow is smart enough to keep the end with the noise upwind from the end that
makes those huge steamers plops. In New York State where level ground is
unheard of, cows tend to walk and stand perpendicular with grade. That way if
they trip they try to fall uphill.  If they fall on unlevel ground with their
legs higher than their body they cannot stand back up and in a fairly short
period of time can die. This is true with milk cows who are not as nimble as
the beefers.

Having grown up in Indiana with lots of cows.   The N/S and E/W orientation of
cows has more to do with winds, sun, and the ambient temperature.

 

perpendicular to the wind direction for cooling /  perpendicular to the sun
for heating........

 

Another case of taking one isolated fact and building a whole house of cards?

 

Almost as good as the 10 year study on air pollution - people who live in
areas with high air pollution have more respiratory problems.  It took
millions of $ and 10 years to figure that one out.

Interesting article on magnetic fields.  

 

Cattle respond to magnetic fields from power lines

By RANDOLPH E. SCHMID, AP Science Writer Randolph E. Schmid, Ap Science Writer

WASHINGTON – High-voltage power lines mess with animal magnetism.
Researchers, who reported last year that most cows and deer tend to orient
themselves in a north-south alignment, have now found that power lines can
disorient the animals.

When the power lines run east-west, that's the way grazing cattle tend to line
up, researchers led by Hynek Burda and Sabine Begall of the faculty of biology
at the University of Duisburg-Essen in Germany report in Tuesday's edition of
Proceedings of the National Academy of Sciences.

They also found that cows and deer grazing under northeast-southwest or
northwest-southeast power lines faced in random directions.

The research team studied cows and deer using satellite and aerial images.

In their report last August, Burda and colleagues suggested the north-south
orientation was in response to the Earth's magnetic field.

The new study adds weight to the animals responding to magnetic effects, since
power lines also produce a magnetic field. And the effect was most noticeable
close to the power lines, declining as the magnetic field of the electric
lines was reduced by distance.

Wind and weather can also affect which ways cows choose to face, but without
such factors about two-thirds of them tended to align north-south when away
>from power lines.

The Earth's magnetic field is thought to be a factor in how birds navigate,
and other animals also are believed to respond to it.

In addition to Burda and Begall, the research team included Julia Neef of the
University of Duisburg-Essen, Jaroslav Cerveny of the Czech University of Life
Sciences and Pavel Nemec of Charles University in Prague, Czech Republic.

The research was supported by the Czech Science Foundation and the Ministry of
Education, Youth and Sport of the Czech Republic.
