Refers to the processing applied in feeding system for pigs at the trough linear, used in the swine farm to ration distribution.Through studies and observations have been developed improvements resulting in functional improvement over the state of the art.The feeding system for pigs at the trough is composed of a linear feeding tube, with the helicoid, powered by a motor, which will feed up secondary tubes,And then the tube feeder (4), which has a flap (4).1) support, and together with cables, regulators and the pendulum (3) and the tip guide (2),Will be used for the determination of ration and a set valve composed of flexible pipes sanfonados (5) connection with reduction (6) in PVC lead out tubes (8) in PVC fixed by clamps (7), but is characterized by having a driver (1) for a flow of feed which has in its constructive models with variation of outputs (1.3), and between three and fifteen outputs (1.3) for the flow of feed openings in the sides, forming a coupling (1.1) for connection with the three screws fixed to the flap (4.1) that support the tube feeder (4) the basis of (1.4) of each output (1.3) with a convex shape and two tenons (1.2) lateral to the internal wall of the driver, built for the connection of the needle guide (2).So, we can get some advantages such as: greater potential for use of the supply system, for various sizes of linear troughs.Keeping the differential adjustment to strength collective and individual, when necessary.refere-se ao aperfeiçoamento em aplicado em sistema de alimentação para suínos em cocho linear, utilizado em granja de suínos para distribuição de ração. através de estudos e observações foram desenvolvidos aperfeiçoamentos resultantes em melhorias funcionais em relação ao estado da técnica. o sistema de alimentação para suínos em cocho linear é composto por um tubo alimentador, com helicóide, movido por um motor, que transportará a ração até tubos secundário, e em seguida até o tubo dosador (4), a qual possui uma aba (4.1) de
