The simulation model of egg production already developed in another study by a postdoctoral student estimates how the nutritional expenses based on no genetic potential and determinant of feed consumption and egg production. This model follows the same principle of Avinesp software, developed without the last thematic project. This is a stochastic model, which takes into account variations within a population of laying hens and breeder hens. The model is a nutritional supplement for maintaining, growing and producing eggs. The studies proposed in this equipment allowed the execution of tasks for the execution of the consumption, taking into account the maximum capacity of the gastrointestinal tract, to estimate food consumption more accurately. In addition, the development of a tool for the evaluation of amino acids, diet consumption and the revenue generated is proposed. When the model is led to a nutritional assessment of the diet, which makes the implementation of a feed formulator relevant, it is more appropriate for the proposed model. The plan to develop the electronic spreadsheet for predicting egg production and the nutritional fisheries of laying hens and breeder hens in software, which will be registered as a software, as well as the calibration and validation of the replicated slides used to perform nutritional surveys by means of of indirect calorimetry of laying hens and breeder hens. As the promotional versions in the production models of matrices and layers provide the development of software capable of simulating egg production, predisposing as nutritional units of laying hens and breeder hens, considering economic factors. The realization of this proposal is a significant advance for a commercial egg and chick production area, favoring a business decision-making regarding the various situations not found in the production system.
