Avaliação da qualidade de silagens de milho produzidas no distrito de Capoerê, Erechim/RS

Abstract

Corn silage is one of the most important feed sources for ruminant production in the different regions of Brazil, including southern of Brazil, where they are mainly used in seasonal voids, moment of transition of forage availability, in the end of winter and summer seasons. The maize (Zea mays) became the main silage plant source, due it contains in this bromatological composition the most important requirements for its ensilage. The purpose of this study was to evaluate the bromatological quality of corn silages produced in the district of Capoerê, located at Erechim, state of Rio Grande do Sul, and was characterized as a case study, where the samples were collected in five different properties. After the samples were collected, the determinations of DM, MM, CP, EE, NDF and pH were carried out in Bromatology Laboratory at Federal University of Fronteira Sul (UFFS). In addition, thermographic reading of the silos was performed with a Thermographic Camera. The Dry Matter ranged from 38.81 to 31.74%. The CP content had high variability among the studied properties, being between 8.14 to 6.52%. It was concluded that, due to results of bromatological parameters, silages produced in the district of Capoerê, Erechim-RS, are in agreement with standards of good silage manufacturing.
