“…The LA content in silage of our study was within this recommended range, an indication of well-fermented silage. However, the LA concentration recorded in our study was lower than 160 g LA/kg DM reported in sweet sorghum silage (Xing et al, 2009) but consistent with that reported by Podkowka & Podkowka (2011). It has been reported that homofermentative LAB or LAB+enzyme inoculation has positive effects on the silage fermentation by increasing LA compared with the control (Kung et al, 1991, Chen et al, 1994.…”

________________________________________________________________________________ AbstractA study was conducted to evaluate the effects of bacterial inoculation and cellulase on the fermentation quality of ensiled whole-crop sweet sorghum (WCSS, Sorghum bicolor L. Moench). The WCSS (323 g dry matter (DM)/kg, 251 g water soluble carbohydrates (WSC)/kg DM, 43 g crude protein (CP)/kg DM and 439 g neutral detergent fibre (NDF)/kg DM) was ensiled with i) no additive (control); ii) Lactobacillus buchneri (LB); iii) Lactobacillus plantarum (LP); and iv) LB+E, a combination of LB and enzyme. These treatments were ensiled in 1 L anaerobic jars for 25 days. The jars were opened on days 3, 7 and 15 to determine pH, while those of day 25 were sampled to determine nutrient composition, fermentation characteristics and aerobic stability. Inoculation reduced pH, butyric acid and ammonia-N and increased lactic acid content in sweet sorghum silage compared with the control. The aerobic stability of WCSS was improved with LB, while it was reduced with the homofermentative LP treatment compared with the control. The LB+E reduced the fibre, but increased residual WSC of silage. The aerobic stability of LB+E silage was lower than LB treated silage. Using enzymes to increase the WSC content of crops that already have high levels of WSC may result in reduced aerobic stability of silage. Further work is needed to evaluate these effects on silage produced on farm scale and on animal production performance. ________________________________________________________________________________

“…Saccharine varieties have a succulent stem and, as a result, showed high effluent production (Podkówka & Podkówka, 2011) França et al (2011) using forage varieties. This excessive effluent can promote the development of anaerobic bacteria of the genus Clostridium, which produce butyric acid, resulting in the degradation of protein and lactic acid.…”

“…All varieties presented satisfactory performance (Coan et al, 2007;Podkówka & Podkówka, 2011;Dias et al, 2014) in the studied parameters, except effluent production, which must be reduced to ensure a more appropriate use of nutrients from the silage produced from the saccharine varieties.…”

-The objective of this work was to evaluate four cultivars of saccharine sorghum (Sorghum bicolor) regarding productivity, chemical composition of plant parts, and quality of the ensiling process. The tested varieties of saccharine sorghum were BRS 506, BRS 508, BRS 509, and BRS 511. The experiment was divided into two trials, which assessed: production, morphological composition, and nutritional quality of the saccharine varieties; and fermentation quality and nutritional value of the silage produced from the saccharine varieties. Of the tested varieties, BRS 509 and BRS 511 showed the highest total dry matter (DM) production. The BRS 508 variety presented the highest in vitro digestibility of the whole plant (70.65% DM). During ensiling, the BRS 509 variety showed the lowest DM loss (8.87%). The highest effluent production was observed for BRS 506 and BRS 508, with yields of 521.87 and 393.16 kg Mg -1 ensiled DM, respectively. The BRS 511 variety is the most recommended because of the best results for plant production and nutritional quality. Regarding the ensiling process, BRS 509 presents the lowest fermentation losses and the highest nutritional value of silage.Index terms: Sorghum bicolor, forage system, nutritional value, roughage, ruminant. Potencial forrageiro e qualidade da silagem de quatro variedades de sorgo sacarinoResumo -O objetivo deste trabalho foi avaliar quatro variedades de sorgo sacarino (Sorghum bicolor)quanto à produtividade, à composição química das partes da planta e à qualidade do processo de ensilagem. As variedades de sorgo sacarino utilizadas foram BRS 506, BRS 508, BRS 509 e BRS 511. O experimento foi dividido em dois ensaios, que avaliaram: produção, composição morfológica e qualidade nutricional das variedades sacarinas; e qualidade do processo fermentativo e valor nutricional das silagens das variedades sacarinas. Das variedades testadas, a BRS 509 e a BRS 511 foram as que apresentaram maiores produções de matéria seca (MS) total. A variedade BRS 508 apresentou o maior coeficiente de digestibilidade in vitro da planta inteira (70,65% da MS). Durante a ensilagem, a variedade BRS 509 foi a que apresentou menor perda de MS (8,87%). A maior produção de efluentes foi observada para BRS 506 e BRS 508, com produção de 521,87 e 393,16 kg Mg -1 de MS ensilada, respectivamente. A variedade BRS 511 é a mais indicada em razão dos melhores resultados de produção e de qualidade nutricional da planta. Em relação ao processo de ensilagem, a BRS 509 apresenta as menores perdas fermentativas e o maior valor nutritivo da silagem.Termos para indexação: Sorghum bicolor, forragicultura, valor nutritivo, volumoso, ruminantes.

Sorghum contains less protein and energy than maize, however (Oliver et al, 2004;Staggenborg et al, 2008;Podkówka and Podkówka, 2011).…”
