The experiment was conducted at the Núcleo de Produção Animal of the Universidade Estadual do Centro Oeste do Paraná (UNICENTRO). It was aimed at evaluating the silage obtained quality and dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) losses occurred during fermentative process on two silos type (PVC type and commercial type) as well as evaluate the compact efficiency of silage. The forage used was corn plant harvested of the different particle sizes (small between 0.2 and 0.6cm or large between 1.0 and 2.0cm) and cutting heights (low cut 15cm or high cut 39cm), using three replication (silos type) for every silage, contained eight treatments in factorial scheme 2 x 2 x 2. The values of dry matter and crude protein contend of the silages no presented effect associated or isolated (P>.05) front of particle size (small and large), height cutting (low and high) and conservation silo type (PVC type and commercial type). On the other hand, the production silages in silos PVC type and commercial type showed differences for parameters organic matter, neutral detergent fiber and N amoniacal contends, as well amount of pH, compact efficiency, and crude protein and neutral detergent nitrogen losses. The compact efficiency also was affected (P .05) buy the silage particle size.
