“…Formic acid was able to restrict fermentation indirectly by limiting the activity of LAB to produce lactic acid. The result was consistent with that reported by Saarisalo et al (2006), but different from that reported by Aksu et al (2006) that formic acid supplementation did not alter lactid acid concentration. These results suggest that the effects of formic acid on lactid acid concentration are inconsistent.…”

“…Formic acid as a fermentation inhibitor reduced the degradation of protein in the rumen. This result is supported by the data reported by Aksu et al (2006) that acid treatment reduced the apparent digestibility of crude protein in the rumen through its effect on preventing the conversion of protein to ammonia that eventually increased the proportion of by-pass protein entering the duodenum. This result indicated that the application of formic acid was an important factor in determining the effect of formic acid on the fermentation,the synthesis of microbial protein in the rumen, and the supply of nutrients to the ruminants (Jaakola et al, 2006).…”

The potential availability of forage feed is high, but in reality this potential has not been able to meet the requirement of feed both in sustainable quantity and quality. Silage made with the use of liquid fermentation additive (FA) can be a solution for those problems. The use of different levels of FA and addition of Lactobacillus plantarum bacteria as well as formic acid were expected to improve the nutritive quality of napier grass silage. The first experiment was designed to measure the fermentative quality of napier grass silage. The treatments used were the levels of FA, L. plantarum, and formic acid supplementations. The experiment used a completely randomized design with a 3x2x2 factorial arrangement with 3 replications. The first factor was the level of liquid FA (5%, 7.5%, and 10%), and the second factor was the inoculation of L. plantarum (without and with inoculation of the L. plantarum), and the third factor was the addition of formic acid (without and with the addition of 0.15% formic acid). The second experiment was aimed to evaluate chemical and microbiological characteristics, and in vitro digestibility of selected napier grass silage. The results showed that napier grass silage from all treatments showed good qualities. There were interactions between FA, L. plantarum, and formic acid on DM content (P<0.05) and ammonia production (P<0.01). The use of FA showed an interaction (P<0.01) with the addition of L. plantarum and formic acid in Fleigh point. Ammonia production in rumen (P<0.01), total VFA (P<0.05), and in vitro digestibility (P<0.01) were significantly affected by the treatments. The optimal level of liquid FA was 7.5%. Based on the nutritive quality of silage, L. plantarum addition was as effective as control treatment to improve nutritive quality of napier grass silage through the increased of fermentation characteristics i.e., low pH, high DM product, high fermentation product (VFA), and digestible on rumen. Formic acid reduced ammonia production during ensiling and fermentation in rumen, but it was less effective in inhibiting the fermentation process when it was combined with L. plantarum.

Silase dibuat dengan cairan aditif fermentasi (AF) sebagai solusi permasalahan di atas. Melalui evaluasi level penggunaan AF dan penambahan bakteri Lactobacillus plantarum serta asam formiat diharapkan memberikan pengaruh sinergi dalam meningkatkan kualitas nutrisi silase rumput gajah. Percobaan pertama menguji kualitas fisik dan fermentatif hasil akhir silase rumput gajah. Kualitas fermentatif menggunakan rancangan acak faktorial 3 x 2 x 2 dengan 3 ulangan. Faktor pertama adalah level cairan aditif fermentasi (5%, 7,5%, dan 10%), faktor kedua adalah inokulasi L. plantarum (tanpa dan dengan inokulasi L. plantarum), dan faktor ketiga ...

RESUMO -Dois experimentos foram realizados para avaliar o valor nutritivo, a estabilidade aeróbia de silagens de cana-de-açúcar e a digestibilidade aparente de rações contendo essas silagens. No experimento 1, a cana-de-açúcar foi ensilada sem aditivo ou inoculada com cepas NCIMB 40788 do Lactobacillus buchneri (5 x 10 4 ufc/g de matéria verde). Amostras das silagens foram analisadas e comparadas à cana-de-açúcar in natura para avaliação da estabilidade aeróbia, considerando os dados de temperatura, pH e perdas de MS das silagens. No experimento 2, utilizaram-se 12 cordeiros distribuídos em blocos completos casualizados e mantidos em gaiolas para ensaio de metabolismo recebendo rações contendo cana-de-açúcar in natura, silagem de cana-de-açúcar sem aditivo ou silagem de cana-de-açúcar tratada com Lactobacillus buchneri. Os teores de matéria seca, carboidratos solúveis e ácido acético foram maiores na silagem com aditivo. O teor de etanol não diferiu entre as silagens. A silagem tratada com aditivo apresentou menor perda de matéria seca e manutenção do pH durante o período de avaliação em aerobiose. A digestibilidade aparente de fibra em detergente neutro, fibra em detergente ácido e hemicelulose foram maiores nas rações contendo silagem de cana-de-açúcar. Palavras-chave: ácido acético, bactérias heterofermentativas, composição química, digestibilidade aparente, etanolEffect of Lactobacillus buchneri on fermentation, aerobic stability, and nutritive value of sugar cane silage ABSTRACT -Two trials were performed to evaluate the nutritive value and aerobic stability of sugar cane silage, as well as apparent digestibility of diets containing these silages. In trial 1, sugar cane was ensiled without additive or inoculated with strains NCIMB 40788 of Lactobacillus buchneri (5 x 10 4 cfu/g wet basis). Silages were sampled, analyzed, and compared with fresh sugar cane. Aerobic stability was evaluated by controlling the temperature, pH, and dry matter losses of the silages. In trial 2, twelve lambs were assigned to a complete randomized block design and placed in metabolism crates and fed with diets composed by fresh sugar cane, sugar cane silage without additive, or sugar cane silage treated with Lactobacillus buchneri. Dry matter, soluble carbohydrates, and acetic acid concentrations were higher for silage treated with Lactobacillus buchneri when compared with silage without additive. There was no difference on ethanol levels between silages. Sugar cane silage treated with Lactobacillus buchneri showed lower dry matter losses, unchanged pH, and greater aerobic stability. Neutral detergent fiber, acid detergent fiber, and hemicellulose apparent digestibility were higher for sugar cane silage treatments.Key Words: acetic acid, apparent digestibility, chemical composition, ethanol, heterofermentative bacteria IntroduçãoAtualmente, a conservação de cana-de-açúcar na forma de silagem tem despertado o interesse de pesquisadores e produtores, sobretudo em virtude dos benefícios em logística e operacionalidade desta técnica.De...

“…This is consistent with the lower AA, PA, BA and ammonia N concentration observed in the silages with molasses in the study. Compared to rice straw silage, molasses addition alone significantly decreased NDF and ADF, probably due to acid hydrolysis of cell walls carbohydrates resultant from reduction in silage pH by lactic acid fermentation (AKSU et al, 2006;JONES et al, 1992).…”
