Effect of sealing on the feed out face of trench silos on the performance of confined calves

ABSTRACT This study aimed to evaluate the productive performance, dry matter intake, apparent digestibility and ingestive behavior of feedlot calves fed corn silage from feed out face trench silos with different types sealing. The animals were divided into three treatments four repetitions: Conventional seal - double-sided polyethylene 110µm thickness; Double-sided 200µm Double composed double a thickness 80µm superimposed on polyamide translucent vacuum film 20µm. use sealing provided 12.63% increase in average daily gain improved food conversion by 0.62 percentage points. diet double-face system was 4.30% higher than 11.00% conventional silage. It is recommended thick top 20µm film.
