“…The content of CP in our WCSS is lower than those reported in sweet sorghum silage (Morris & McCormick, 1994, Di Marco et al, 2009, Xing et al, 2009, which ranged between 77 and 95 g CP/kg DM. This difference could be attributed to different hybrids, soil conditions and harvest stage between the two studies (Lema et al, 2000).…”

________________________________________________________________________________ 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. ________________________________________________________________________________

“…Fibre fractions in forages and silages (i.e., NDF, ADF and ADL) were lower in HS and MZ than FS and it indicates that HS and MZ contained less plant cell wall including hemicellulose, cellulose and lignin than FS (Van Soest, 1991). The difference in fibre content may be related to the genotypes of the forage (Kruse et al 2008;Oliver et al 2004;Di Marco et al 2009;Norman et al 2013) and the variations in leaf to stem ratio (Elseed et al 2007).…”

The chemical composition, mineral profile and in-vitro fermentation characteristics of maize (MZ), high sugar forage sorghum (HS) and forage sorghum (FS), and silages made from each forage type were measured. The MZ and MZ silage (MZS) had higher crude protein, starch and ether extract contents than both sorghum forages and sorghum silages. HS had higher ash and water-soluble carbohydrate concentrations than FS and MZ. MZ, MZS, HS and HS silage (HSS) had lower neutral detergent fibre, acid detergent fibre and acid detergent lignin than FS and FS silage (FSS). FSS had higher DM and pH than MZS and HSS. HSS contained higher concentrations of P and K than FSS and MZS. MZS and HSS had higher in-vitro dry matter and organic matter digestibility, CH 4 production, total volatile fatty acids, acetate and propionate than FSS. pH was higher for FSS than HSS, and ammonia was lower for HSS than MZS and FSS. HSS had higher gas production than MZS and FSS after 2, 4, 6 and 8 h incubation. MZS had higher gas production than HSS and FSS after 26 and 28 h of incubation. The results indicate that HS may substitute for MZ to make good quality silage. However, animal studies are needed to assess the acceptability and feeding values of HSS versus MZS for ruminant production.

“…Previous studies have shown that conversion efficiency is inhibited by compositional components such as lignin (Yoshida et al 2008, Zhao et al 2008) and hemicellulose (Yoshida et al 2008). The lignin content of cellulosic biomass has also been shown to differ significantly between different sorghum genotypes (Di Marco et al 2009, Vandenbrink et al 2011). It has also been shown that lignin differs between tissue types of the same genotype (Billa et al 1997).…”

Quantitative models of hydrolysis conversion efficiency and biomass crystallinity index for plant breeding

et al. 2013

In conjunction with improvements to processing technology, selective breeding can be used to increase bioenergy yield potential either through an increase in total harvestable biomass or by modifying biomass conversion efficiency. In this study, the measurement of biomass composition (lignin, cellulose and hemicellulose) and proximate (fixed carbon, volatile matter, ash and moisture contents) components was conducted on leaf and tissue samples from diverse Sorghum bicolor genotypes across two environments. Multiple regression analysis was used to create models that predict two biomass conversion traits: hydrolysis yield potential (HYP) and crystallinity index (CI). CI model variables included tissue type, ash and lignin. HYP model variables included tissue type, ash, cellulose and volatile matter. The presence of ash content in all models was a salient finding of our study. Given that several models were able to predict HYP and CI in alternate grow‐out years, these models may be useful in selective breeding programmes aimed at sorghum bioenergy feedstock improvement through increased conversion efficiency.
