A cow is an animal, &
 animals are creatures.
  So, having strong proclivities
    is a cardinal feature.

Calling them "creatures of habit"
 must be for a reason.
  If creatures did not form habits
   the term would lose cohesion.

But I digress, I must admit.
 Let me get to my point.
  You see, a sloping pasture must
   be murder on the joints!

A random beast, who stood this way
 & that, would balance out,
  but standing each day - just one way -
   could cause a hip blowout.

A cow that grazes on a pitch
 must have unequal legs.
  Maybe, all it would take would be
   two tiny pirate pegs.

For wearing pegs on the downslope
 side would align the hips,
  but then on walks down to the barn
   cows would be prone to trips. 

For now, there's just one solution:
 bovine chiropractors!
  Because the cost will be so great,
   I'm seeking benefactors.
