The grass is always greener.

   I really like this fine cartoon and I’m sure the  author  wanted to humorously illustrate the old ‘grass is greener” adage and also possibly comment on the pure cussedness of some cows in their distain for fences, 

   However, upon further reflection, this drawing illustrates 2 very importnt principles of animal nutrition.   1.  No two animals have the same nutritional needs.   2.   All soils, crops and feeds differ in their mineral content. 

    The feeding activity of these two cows demonstrates the above principles in that each cow is satisfying it’s own specific needs by seeking out what it needs no matter which side of the fence it is on.

    This concept was explained in the 1950’s by Dr. Wm Albrecht’s film- aptly named “The Other Side of the Fence”.
