Optimization Of The Production Process Of Pelletized Feed For Pigs In The Fattening Stage

Abstract

The production of balanced feed for pigs is a sector in the highly competitive industry that is characterized by establishing small margins between costs and benefits. A goal optimization model was applied to reduce the production cost and guarantee the amount of corn in the formulation. For this purpose, multi-objective programming was applied, with two defined goals and nine restrictions related to compliance with fat, fiber, moisture, and protein content. RStudio was used to find the most feasible formulation. With the establishment of goals and priorities, the optimal formulation is 24.3% corn, 11.60% calcium carbonate, 23.90% cane molasses, 19.30% monocalcium phosphate, 20.90% concentrated soybeans, and a negligible amount of palm oil. The results obtained in the deviation variables indicate compliance with the goal related to the minimum cost and non-compliance with the goal that guaranteed the minimum amount of corn in the formulation. The mathematical model developed may present variations if restrictions change, new variables are introduced, or changes in costs for the raw material used.
