“…The WSC of the SM group was increased due to mixing S and M forages, leading to improved LA content (Table 2). The results derived from this study were in agreement with the findings of Kaplan (2013) and Pinho et al (2015), who stated increased level of WSC enhanced the LA content of silage and accounted for a lower pH value. a,b,c Values within a row with different superscripts differ significantly at P<0.05 DM: Dry Matter, g kg -1 ; CP: Crude Protein, g kg -1 DM; Ash, g kg -DM; NDF: Neutral Detergent Fiber, g kg -1 DM; ADF: Acid Detergent Fiber, g kg -1 DM; ADL: Acid Detergent Lignin, g kg -1 DM; Hcell: Hemicellulose, g kg -1 DM; Cell: Cellulose, g kg -1 DM; WSC: Water Soluble Carbohydrate, g kg -1 ; NH3-N: Ammonia Nitrogen, g kg -1 TN; LA: Lactic Acid, g kg Differences with respect to the CP and ash content among the silage groups were found significant (P<0.01).…”

“…This result was expected because it was stated by some researchers in the earlier studies that the forage quality may strongly be affected by species, genotype, maturity at harvesting period, steam/leaf ratio, number of panicles (Cândido et al, 2002;Da Silva et al, 2012). The results were consistent with an adequate CP level for the functioning of ruminal microbiota (Pinho et al, 2015). Ash referring to mineral content in forages, influenced by maturity, is found higher in seed than those of other parts.…”

“…Sorghum (Sorghum bicolor L. Moench) is characterized by drought resistance and salinity tolerance, high water-soluble carbohydrates, and greater biomass yield than maize (Rocateli et al,2012;Pinho et al, 2015). Moreover, dual-purpose sorghum hybrids can reach 68% more dry matter (DM) yield than wild ones due to their number of panicles (Da Silva et al, 2012).…”

The current study aimed to determine the nutritional quality and aerobic stability of sorghum, maize, and their mixture silages without any additives. Sorghum and maize were harvested at dough stage from a local farm in Tekirdağ. Fresh plant materials were chopped to a length of 2-3 cm and packed into polythene bags, and vacuumed. A total of 12 vacuum-packed silos (4 replications in each treatment) were prepared with sorghum (S), maize (M), and a mixture of sorghum-maize (SM) forage (w:w, 50:50 according to dry matter) and stored at room temperature for 60 days. The chemical and microbiological composition of silages with the rate of aerobic deterioration upon aerobic exposure were evaluated. Based on the pH and ammonia nitrogen concentration, all silages could be classified as good quality. The water-soluble carbohydrate level of the SM group increased due to mixing S and M forages, leading to improved lactic acid content. The NDF and ADF values of silages varied between 520.52-588.32 and 234.98-309.01 g kg -1 , and the differences between silages were significant (P<0.01). The Hemicellulose/Cellulose ratio of S, M, and SM silages were found 0.94, 1.49, and 1.18, respectively. The lactobacilli and yeast content of silages were significant and varied between 5.18-7.41 and 5.18-7.29 log cfu g -1 , and the highest and lowest values were observed in SM and S silages, respectively (P<0.01). No visible mold was detected in all silages after 5 days of aerobic exposure (P>0.05). The pH, CO2, and yeast numbers were varied in groups between 4. 88-6.74, 55.71-119.33 g kg -1 , and 8.40-9.01 log cfu g -1 . It was concluded that it is possible to improve the nutritional and fermentation characteristics of sorghum and maize silage by ensiling their mixture. However, it is highly recommended that silage additives should be used to guarantee and strengthen the fermentation and aerobic stability of silage mostly made by a mixture of these two energetic forage crops.

“…According to Pinho et al (2015), lower levels for these acids are associated with the rapid acidification of the medium, due to its susceptibility to low pH values.…”

Sorghum stands out among other plants recommended for ensiling due to its forage composition, its resistance to drought, and its planting range. New cultivars of grain and sweet sorghum that can be used for silage production are available, but there is little information regarding their ensiling characteristics. The aim of this study was to evaluate the fermentation characteristics at the ensiling of different purpose sorghum cultivars, at two crop periods. The trial was carried out at the Plant Production Department of the Federal Institute of Education, Science and Technology of Rondônia, Colorado do Oeste campus, Rondônia, Brazil, and chemical analyses were performed at the Laboratory of Animal Nutrition, at the Federal University of Mato Grosso, Cuiabá campus, Mato Grosso, Brazil. The experimental design used was a randomized block, in split-plot design, with four replicates. The plot treatments consisted of six sorghum cultivars grown for different purposes (grain sorghum: BRS 308 and BRS 310; forage sorghum: BR 655 and BRS 610; sweet sorghum: BRS 506 and CMSXS 647). Split-plot treatments consisted of two cropping seasons (first crop and second crop). The grain sorghum cultivar BRS 310 was the only one that had suitable dry matter content for ensiling; however, it was also the only one that did not show ideal water soluble carbohydrate content for ensiling. Nevertheless, all treatments presented pH below than 4.2 and ammonia nitrogen lower than 12% of total N, which indicates that the fermentation inside the silo had proceeded well. For sweet sorghum cultivars, higher ethanol and butyric acid content were observed for the first crop than for the second crop. All evaluated sorghum cultivars can be used for silage production, but the use of sweet sorghum is recommended at the second crop. Key words: Alcoholic fermentation. Fermentability coefficient.

“…The bacterial activity that occurs during ensiling decreases as DM content increases (KAISER et al, 2004), which reduces the production of organic acids, such as lactic acid, consequently decreasing the rate of pH reduction. In addition, elevated levels of WSC promote vigorous fermentations within the silo (PINHO et al, 2015). Zhang et al (2015), evaluated the quality of sweet sorghum silages and observed pH values of 4.16 and N-NH 3 of 7.66 % of total N. Regarding silages of sweet sorghum cultivars, the lower DM content observed at the first crop than at the second crop may have been due to higher ethanol production (Table 4).…”
