“…Another trait of importance related to livestock productivity is the digestibility of silage DM, and particularly that of the neutral detergent fibre (NDF) fraction. Sorghum forage, especially of BMR varieties, may have high nutritive value, which might be comparable to that of corn 4, 6, 10, 11…”

The effect of growth stage and re-growth on the nutritional and ensilage characteristics of two new sorghum hybrids, BMR-101 and Silobuster, and one commercial variety, FS-5, was examined in this study. Varieties were sampled during the summer at the early heading (EH) stage and were harvested at the soft dough (SD) stage. Additional irrigation enabled autumn re-growth and a second harvest. Plants of FS-5 and BMR-101 were resistant to lodging at EH. However, BMR-101 and Silobuster suffered from high lodging at the SD stage of the summer harvest. Dry matter (DM) content of FS-5 and BMR-101 at EH was below 250 g kg −1 . DM yields of the varieties were similar at the summer harvest and higher than their respective re-growth cuts. Ensilage DM losses were moderate and similar across varieties. Hemicellulose of SD plants was partly solubilised and most of the water-soluble carbohydrate fermented, yielding lactic acid, ethanol and volatile fatty acids (VFA), and a pH < 4. In vitro DM digestibility of varieties was similar in summer silages, but lower in the respective re-growth silages of FS-5 and BMR-101, reflecting the higher content of neutral detergent fibre and lignin in the re-growth silages. The summer plus re-growth cumulative yields of digestible DM of the respective FS-5, Silobuster and BMR-101 silages were 14.7, 16.6 and 14.5 t ha −1 . The commercial variety, FS-5, may have some advantage over BMR-101 and Silobuster owing to its relative resistance to lodging in addition to its high yield and good ensilage properties.

Intake and digestibility of sorghum (Sorghum bicolor, L. Moench) silages with different tannin contents in sheep

et al. 2014

-The purpose of this study was to evaluate the voluntary intake and digestibility of three sorghum (Sorghum bicolor, L. Moench) hybrid silages in sheep. The hybrids used were H1 -BRS 655 (CMSXS 222 A × CMSXS 235 R), with tannin; H2 -(ATF54 A × CMSXS 235 R), without tannin; and H3 -BRS 610 (CMSXS 232 A × CMSXS 234 R), without tannin. The intake and digestibility of dry matter (DM), gross energy (GE), neutral detergent fiber (NDF), acid detergent fiber (ADF) and crude protein (CP) were measured. Eighteen crossbred sheep weighing 59.4 kg (±8.3) were used in the trial. A completely randomized design with three treatments (hybrids) and six repetitions (sheep) was used. There were no differences in the DM intake or apparent digestibility among the hybrids. Silage of hybrid BRS 610 displayed higher digestibility coefficients for CP, NDF, ADF, and GE compared with the other silages, which did not differ from each other. The neutral detergent fiber, ADF and digestible energy (DE) intakes were similar among the hybrids silages. All of the hybrids resulted in a positive N balance in sheep. The levels of DE were superior in hybrid silage BRS 610 in comparison with the other hybrids. Sorghum hybrid BRS 610 silage exhibited superior nutritional value compared with the other hybrids, which is most likely in part due to the absence of tannins. Sorghum silage made with hybrid BRS 610 (CMSXS 232 A × CMSXS 234 R) presents superior gross energy, crude protein, neutral detergent fiber and acid detergent fiber digestibility coefficients, as well as greater digestible energy levels than BRS 655 (CMSXS 222 A × CMSXS 235 R) and (ATF54 A × CMSXS 235 R).

“…(1989) found that sorghum contained higher CF (Tables 6,7) and lignin concentrations than those of maize. According to Miron et al . (2005) higher NDF and lignin concentrations of plant probably affected plant resistance to waterlogging.…”

The effects of three levels of manure application (0, 4 and 8 ton/10 a) with basic fertilizer (N : P : K = 10:10:10 kg/10 a) on the yield and chemical composition of maize (Pioneer 32K61) and sorghum (FS501) forages were examined in 2 successive years, 2001–2002. Maize was harvested at yellow ripe stage, while sorghum at dough stage. Dry matter yield (DMY) of sorghum was significantly higher than that of maize in both 2001 and 2002. Although, DMY of both sorghum and maize were not significantly affected by manure levels in 2001, they increased with the level of manure in 2002. Maize had higher levels of crude protein (CP) and lower crude fiber concentration than those of sorghum in both 2001 and 2002. Manure application had no effect on chemical compositions of both maize and sorghum except for CP in both years and organic a fraction (Oa) concentration in 2002. The higher manure application might have greater effects on sorghum and maize production because of higher DMY in the second year without any increase in fiber fraction.
