Abstract

This work was set out to evaluate productivity, nutritional and fermentation characteristics of different sorghum cultivar silages. The experimental design was randomized blocks with three replications. The results were submitted to ANOVA and mean values of each cultivar were used for an orthogonal contrasts study (forage sorghum vs. double purpose sorghum silages). Results of fermentative characteristics showed that all cultivars presented potential for ensilage. Double purpose sorghum silages showed higher (p < 0.05) dry matter content (38.32%) when compared to forage sorghum silage (33.01%), as well as for pH values. Likewise, double purpose sorghum silages showed significant, increased levels of CEL (25.30%) and K (1.16%). Forage sorghum cultivars showed higher (p < 0.05) productivity (17527 kg ha-1 of dry matter) when compared to double purpose sorghum productivity (13006 kg ha-1 of dry matter).
