Abstract
In this work, we analyse the chicken production in a poultry network composed of a set of farms that serves a slaughterhouse in the city of Tlemcen. Each farm has a chicken house dedicated to breeding, and each chicken house has three breeding modes: manual breeding, semi-automatic breeding, and automatic breeding. And each mode consumes an appropriate energy level depending on the degree of automation used, which directly affects the quality of the chicken. The objective of this study is to determine the best energy adaptation within the farm to obtain good quality chickens. The problem of this activity is the choice of the right energy level of breeding, which consumes a minimum energy value, and gives a good quality of chickens. Knowing that the quality improves with the increase of energy, this study serves to develop mathematical modelling of two objectives: minimization of energy consumption and maximization of the chicken quality produced. The two objectives are optimized independently, and then they are joined by adapting the LP-metric method to help the breeders choose the optimal energy level to obtain good quality chickens.
Highlights
Among the sectors that have undergone an important evolution through time is the agri-food sector, whether for the vegetables and fruits consumption or the meat and chicken consumption

Summary
Among the sectors that have undergone an important evolution through time is the agri-food sector, whether for the vegetables and fruits consumption or the meat and chicken consumption In the protein family, the broiler chicken is the most consumed product compared to other meats, and this is mainly due to its reasonable price, which is in line with the average individual's income, and its availability on the market justified by the short production cycle. (Kaci and Kheffache, 2016; Tahraoui et al 2020) [2][3] This encourages farmers to invest in this field of broiler breeding to conquer the market. This market conquest remains a challenge in front of an increasingly demanding consumer. This requirement remains remarkable on the chicken quality. That is why many breeders are trying to find mechanisms to improve quality while keeping a minimum energy consumption
