The Techniculture Compound Calculator is owned by Berry Feed Ingredients and was invented in 1964 by
 Dr D.G.A Guttridge and latterly patented. This instrument was the forerunner of computer feed formulation.

 The compound calculator simplified the calculations for formulating measures of ingredients
 and has now been superseded by computer programs.
