Avaliação nutricional e perdas de nutrientes durante a fermentação e estabilidade aeróbica de silagem de milho inoculadas com Lactobacillus Buchneri

Abstract

Livestock production has intensified throughout the country. Within this area the dairy cattle has great featured. The corn silage is used worldwide, and the forage storage in the form of silage allows the supply of roughage fed to ruminants in periods of shortage of pasture. This study aimed to evaluate the possible losses of nutrients during the fermentation of corn silage, with the use of microbial inoculant and the effects of exposure of silage on the air, about the pattern of fermentation, during desensilagem. The experiment was conducted in a private country estate in the municipality of Santo Antônio do Sudoeste. The site is located in southwestern Paraná region, Brazil. Approximately 23 plants were mashed in average particle size from two cm for confection of mini silos with compaction density approximate 611.5 kg / m³ of green matter. We evaluated the efficiency of microbial additive from the evaluation of inoculated silos and without inoculation after 42 days of fermentation to determine nutrient losses after the fermentation and after opening silos. As analyzes were performed in Bromatology Laboratory of the Federal University Frontier South Campus Realeza. The average levels of the nutritional composition of silage inoculated for PB, NDF, ADF were 7.61; 59.19; 26,43 respectively. The average fermentative standard data pH 4.16 and 4.42 and 38.05% dry matter and 35.8% for control and inoculated with L. buchneri, respectively.
