It is not enough to have a good formulation computer program; we also need to ensure the operator is highly trained in both basic nutrition principles and practical feeds and feeding science.
I recall a time when feed formulation, for me, was a world full of wonderment and perplexity. I was an undergraduate in animal science, and I was hopelessly trying to find books about how to formulate programs. At that time, MS-DOS was reigning, and feed formulation software was more valuable than gold — at least this is what some of my mentors led me to believe. Undaunted, however, I built my own feed formulation program using an IBM algorithm that I found at the university’s library and Fortran C (a software-developing language). Lamentably, I no longer have these things in my possession, but I do recall spending countless hours formulating diets for pigs and poultry.
