Efeito do farelo de trigo sobre as perdas, recuperação da matéria seca e composição bromatológica de silagem de capim-mombaça

Abstract: Objetivou-se avaliar o efeito da inclusão de farelo de trigo sobre as perdas, recuperação da MS e qualidade de silagem de capim-mombaça, em um experimento inteiramente casualizado com quatro tratamentos: 0, 20, 40 e 60% de farelo de trigo, e quatro repetições por tratamento. Foram utilizados baldes com capacidade para 15 litros, dotados de válvula de bunsen, para escape dos gases e com 3 kg de areia adicionados no fundo para retenção dos efluentes. As variáveis avaliadas foram perdas por gases, perdas por eflu… Show more

“…The gas losses were quantified in the silages after the mini-silos were opened, applying the equation proposed by Zanine et al (2006): GL = {SWC -SWO / FMC × DMC} × 100, where GL is the gas losses during storage (% of the initial dry matter); SWC, the weight silo at ensiling; SWO, silo weight at opening; FMC, forage mass at ensiling; and DMC, the dry matter content of the forage at ensiling.…”

“…Elephant grass does not make good silage, however, because of its high moisture content at the time of harvest and its low levels of the soluble carbohydrates that are required for the development of lactic acid bacteria during the fermentation process (LAVEZZO, 1994). As a result of these factors, there may be a loss of soluble nutrients in the form of wastewater because of the excess elephant grass moisture, and also a loss of nutrients in the form of gases generated by secondary fermentation, a process caused by spoilage microorganisms, mainly Clostridium bacteria, that develop in high humidity environments and produce ammoniacal nitrogen and butyric acid (ZANINE et al, 2006a).…”

“…To inhibit the growth of these undesirable microorganisms and minimize losses due to secondary fermentation, water-absorbing additives have been used containing dry matter and soluble carbohydrates (ZANINE et al, 2006b). Thus, the by-products of processing such fruits as acerola, cashew, passion fruit, and pineapple, among others, could play important roles in improving elephant grass silages (CRUZ et al, 2010).…”

“…Uma forma de reduzir as perdas de nutrientes na forma de gases é a adição de coproduto com alto poder higroscópico que aumente o valor nutricional e beneficie a fermentação durante o processo de conservação da forrageira, como, por exemplo, o farelo de trigo (Zanine et al, 2006a, Zanine et al, 2006b), a raspa de mandioca (Zanine et al, 2010), o farelo de arroz, a casca de soja e o fubá de milho (Monteiro et al, 2011).…”
