1. Fernández Romay, Yulien. Modelización del sistema productivo porcino y evaluación de los parámetros técnicos más significativos.

Degree: Departament de Producció Animal, 2013, Universitat de Lleida

Two models were used for this study. The first model optimizes replacement policy and the second model simulates a farms of sows and were adapted and created to estimate and compares technical and economic indices on pig breeding farms. The first model optimizes technical and economic indices of farms through optimization prolificacy as the most important index in the numerical productivity of sows, the second model was designed to simulate and employment globally farm performance.For optimization of the technical and economic indices were estimated curves prolificacy of five populations from five different genetic origins and obtained data from 53 farms, 24 Spanish, 19 Danish and 10 Cuban, prolificacy curves in order of birth were obtained from the calculation of the parameters estimated by the model. The parameters are obtained from the register of the different events of the bristles and includes the following features: farm identification, identification of the sow, parity and number of piglets born alive, the results of the optimization of the technical and economic indices have shown a better technical performance for farms from Denmark with a significance level (α <0.05), and showed that high replacement rates would be compensated financially by the rate of piglets weaned. The model of discrete event simulation, was adapted to contemplate a batch management and takes into account the daily tasks of the farms. The main contribution of the model is the flexibility in the organization of production ranging from simple sow farm to a group of them, as actually is done in practice. These features allow the model to determine the difference from other approaches and allow compare different reproductive management strategies and production systems more realistically. Was used to simulate a Cuban farm and propose a management strategy to improve the productive results of it. Advisors/Committee Members: false (authoremailshow), Babot Gaspa, Daniel (codirector), Pla Aragonés, Lluís Miquel (codirector), false (authorsendemail).
