Sorghum stands out among others recommended plants for silage due to its optimal levels of water soluble carbohydrate (WSC) and dry matter (DM), but additionally for presenting higher tolerance to drought and greater seeding range compared to corn. Among sorghum types there are: grain; forage and sweet sorghum, which differ in plant height and morphological characteristics. Sweet sorghum can be an interesting alternative for silage production due to its high yield, however it?s ensiling can promote ethanol production in the silo, since the high WSC content provides an ideal environment for the yeast activity that convert, in anaerobic environment, WSC in ethanol. There are new cultivars of sweet sorghum that can be used for silage production, but there is little information about their fermentation characteristics. Goal was to evaluate the organic acids and ethanol content in silages of different sorghum cultivars. Chemical analyses were performed at the Laboratory of Animal Nutrition, at Federal University of Mato Grosso, Cuiabá campus. Experimental design was a randomized block, in spli-plot design, with four replications. Plot treatments consisted of six sorghum cultivars of different purpose (BRS 308 and BRS 310, grain sorghum; BR 655 and BRS 610, silage sorghum; BRS 506 and CMSXS 647, sweet sorghum). Split-plot treatments consisted of crop period (first crop and second crop). Cultivar effect was observed for acetic acid content, while effect of interaction cultivar x crop period was observed for butyric acid and ethanol content. Forage sorghum cultivar BRS 610 and both sweet sorghum cultivars presented higher acetic acid content compared to grain sorghum cultivar BRS 308, probably due to higher DM content. Sweet sorghum cultivars presented higher ethanol and butyric acid content compared to other cultivar at first crop. No difference between cultivars was observed at second crop for both variables. For sweet sorghum cultivars at first crop, the high ethanol content (more than 5% DM basis) observed was probably because of the high WSC content (more than 38% DM basis), while the high butyric acid content (more than 0.2% DM basis) was possibly due to low DM content (less than 20%). This response patter was not observed at second crop, probably because of the lower WSC (lower than 34% DM basis) and higher DM content (more than 22%) observed for sweet sorghum cultivars. All evaluated sorghum cultivars can be used for silage production, but the use of sweet sorghum at first crop promotes silage with high levels of ethanol and butyric acid, being recommended for use at second crop.
