Evaluation of elephant grass silage with the addition of cassava scrapings

Abstract: -The objective of this experiment was to evaluate the effects of adding cassava scrapings on gas and effluent losses, dry matter recovery, pH, contents of N-NH 3 , organic acids and volatile fatty acids and the bromatological composition of elephant grass silages. It was used a randomized complete design, with four levels of cassava scrapings (0, 7, 15 or 30% natural matter) each one with four replications per level. The grass was cut at 50 days of regrowth and ensiled in 15-L silos, equipped with a Bunsen val… Show more

“…O aumento na fração B com a adição de raspa de mandioca pode ter sido ocasionado pelo seu elevado teor de carboidratos solúveis (ZANINE et al, 2010), como explicitado para a jaca. Além disso, a raspa de mandioca apresenta baixas concentrações de FDN, lignina e consequentemente menor participação da fração indigestível nos carboidratos totais (ANDRADE et al, 2010;OLIVEIRA et al, 2010;MAGALHÃES, 2010;ZANINE et al, 2010). Desta forma, a inclusão deste alimento ao capim elefante no momento da ensilagem proporcionou maior disponibilidade de carboidratos fibrosos digestíveis, aumentando a fração B e diminuindo a fração I.…”

“…A utilização da jaca e da raspa de mandioca como aditivos na ensilagem do capim elefante foi inicialmente avaliada no intuito de fornecer carboidratos solúveis para melhorar o perfil fermentativo e reduzir as perdas no momento em que este capim encontrava-se com elevado valor nutritivo (SANTOS et al, 2008;ZANINE et al, 2010). Estes objetivos foram alcançados e alem disso, como constatado no presente trabalho, os aditivos promoveram aumento na degradação ruminal da fibra, ou seja, no valor nutritivo das silagens.…”

“…The samples were centrifuged at 13,000 rpm for 15 minutes and then the analysis of organic acids (lactic acid -LA; acetic acid -AA; and butyric acid -BA) was performed in a high-performance liquid chromatograph (HPLC; Shimadzu) coupled to an ultra violet (UV) detector (SPD-10A VP) using 210 nm as wavelength, with a C-18 reverse phase column at 168 kgf pressure and 1.5 mL/ minute flow. The losses of dry matter (DM) in the form of gas and effluent, and the dry matter recovery (DMR) were estimated according to the equations described by Zanine et al (2010). The density was calculated through the ratio of quantity of fresh forage/volume of each silo.…”
