Silagem de milho ou de cana-de-açúcar com Lactobacillus buchneri exclusivamente ou em associação com L. plantarum

Abstract

5 ufc g -1 de L. buchneri. As silagens foram armazenadas por 150 dias. O tratamento das silagens de milho não afetou a maioria das variáveis relacionadas ao valor nutritivo, às características fermentativas, aos perfis microbiológicos, às perdas e à estabilidade aeróbia. Nas silagens de cana-de-açúcar, o tratamento com L. buchneri apresentou maior teor de matéria seca, sem apresentar diferenças para as variáveis de valor nutritivo. Além disso, foram observados outros resultados típicos da adição de L. buchneri: menor perda total de matéria seca e menores perdas devidas à produção de gases. A aplicação exclusiva de L. buchneri ou em associação a L. plantarum não altera a qualidade e a eficiência de conservação das silagens de milho. Contudo, nas silagens de cana-de-açúcar, a aplicação exclusiva de L. buchneri reduz as perdas de conservação.Termos para indexação: cana-de-açúcar, conservação de forragem, deterioração aeróbia, inoculante, milho. Corn and sugarcane silages with Lactobacillus buchneri alone or associated with L. plantarumAbstract -The objective of this work was to evaluate the effect of Lactobacillus buchneri applied alone or associated with L. plantarum on the fermentation profile, aerobic stability, and nutritive value of corn and sugarcane silages. A completely randomized experimental design was used with four replicates. Treatments for corn silage were: a control without lactobacilli; 1x10 5 cfu g -1 of L. buchneri; and 1x10 5 cfu g -1 of L. buchneri and L. plantarum. For sugarcane silage, treatments were: a control; and 1x10 5 cfu g -1 of L. buchneri. Silages were stored for 150 days. Corn silage treatment did not affect most of the variables related to nutritive value, fermentative parameters, microbiological profiles, losses, and aerobic stability. In sugarcane silages, treatment with L. buchneri showed a higher dry matter content, with no differences for the other nutritive value variables. Furthermore, other typical results regarding L. buchneri addition were observed: lower total dry matter loss and lower losses due to gas production. Addition of L. buchneri, alone or associated with L. plantarum, does not change quality and conservation efficiency in corn silages. However, in sugarcane silages the application of L. buchneri decreases conservation losses.

Chemical composition and fermentative losses of mixed sugarcane and pigeon pea silage

“…However, some undesirable characteristics restrict the use of sugarcane silage, including intense alcoholic fermentation when the forage is ensiled pure (Lopes & Evangelista, 2010;Pedroso et al, 2005), dry matter losses and reduced nutritive value (Rezende et al, 2011), and low protein levels and low-quality fiber (Siqueira, Roth, Moretti, Benatti, & Resende, 2012). To control these undesirable characteristics, many additives have been used, including urea (Ribeiro et al, 2010), calcium oxide (Balieiro Neto et al, 2007), virgin lime and limestone (Amaral et al, 2009), sodium chloride (Rezende et al, 2011) and Lactobacillus buchneri (Sá Neto, Nussio, Zopollatto, Junges, & Bispo, 2013). However, some additives can raise production costs and impact the environment.…”

Effect of a bacterial inoculum and additive on dry matter in situ degradability of sugarcane silage

“…However, L. plantarum is the most common organism found in tropical forage silage (Pedroso et al 2007. Recently, the addition of heterolactic bacteria, mainly the species of Lactobacillus buchneri, has shown better results, especially in exhibiting higher aerobic stability and inhibition of yeast and fungal proliferation (Avila et al 2009;2010;Sá Neto et al 2013).…”

Meta‐analysis of the effects of Lactobacillus plantarum and Lactobacillus buchneri on fermentation, chemical composition and aerobic stability of sugarcane silage

“…Similarly, inoculation of sugarcane silage with L. buchneri has produced inconsistent results on DM loss and aerobic stability Balieiro Neto et al, 2009;Sá Neto, Nussio, Zopollatto, Junges, & Bispo, 2013).…”
