 Applied Significant of Nutrient Interrelationships

 The obvious question arises as to what this information means to the
livestock producer in Florida. Many of the essential nutrients for swine
and cattle are natural constituents of the diet or are synthesized in the
gastro-intestinal tract. However, some of the essential nutrients need to
be provided as supplements to the available feed or forage. Cattle in
Florida should be provided supplemental calcium, phosphorus, copper, iron,
cobalt, trace mineralized salt, and Vitamin A. Currently available infor-
mation does not indicate a need for a supplemental source of other minerals
and vitamins for cattle in this state.

 Swine should be provided supplemental calcium, phosphorus, trace
mineralized-iodized salt, manganese, zinc, copper, iron, niacin, ribo-
flavin, pantothenic acid, vitamin B, vitamins A and D, and possibly
choline (if a heavy corn ration is uilized) and possibly pteroylgutamie
acid. Other minerals and vitamins are usually furnished by feeds or
synthesized by the animal.
