Abstract:
This study was on the development of linear model based software with inclusion of digestible amino acids for least-cost poultry ration formulation. The software model developed in this project used recent advancements in the field of poultry nutrition and feeding, information technology and provided facilities to incorporate commonly used feed ingredients and ideal amino acid profiles. Sixty (60) feed ingredients, thirty (30) nutrients and 1800 (60x30) constraints were considered. Standard Linear Programming (LP) model with incorporating lp_solve (Mixed integer linear programming solver) was used to analyze and determine the most efficient and effective way of compounding the least-cost ration with analyzing ideal amino acid profiles. Taking nutrient composition of each of the available ingredients, cost of ingredients, nutrient requirements of the birds, standard restrictions for formulation and ideal amino acids into consideration a mathematical model was constructed. Lp_solve methods were used in linear model algorithm at the program execution. Facilities were made available to formulate broiler rations based on National Research Council (NRC) standards and Ideal Illinois Chick Protein (IICP) (published by Illinois University) profiles. The model gave rations with equalizing major nutrient requirements at the average inclusion level of commercial Lysine 0.05% and Methionine 0.02%. Equal nutrient requirement gave up to 12 major nutrients with ideal amino acid profiles. The formulation was optimum at 15 iterations.
