ABSTRACT
Our objective was to investigate the effect of different variety and wilting treatment on silage quality and in vitro degradability of whole-plant sorghum. Three sorghum varieties (Numbu, Super 1 and Samurai 1) were ensiled either fresh or wilted and evaluated in a 2 x 3 factorial arrangement. Based on sensory evaluation, colour, smell and sensory index increased after wilting treatment (P < 0.01). Based on chemical quality, pH and NH3-N values were lower in wilted groups than in unwilting sorghum silage (P < 0.01). Compared with non-wilted materials, higher dry-matter (DM) and organic-matter (OM) content were found in wilted materials (P < 0.01). Wilting did not affect crude protein (CP), ether extract (EE), neutral detergent fibre (NDF), acid detergent fibre (ADF), hemicellulose, cellulose, or non-fibre carbohydrate (NFC) content. Samurai 1 sorghum silage had the lowest NDF and ADF, both in non-wilted and wilted materials (P < 0.05). The interaction of wilting and different variety had a significant impact on NDF (P < 0.05), ADF, OM, and CP (P < 0.01). Wilting treatment had no significant impact on all aspects of in vitro degradability. In contrast, variety difference had a significant impact on in vitro degradability (P < 0.01). Results of the current study indicate that wilting treatment influences the sensory score and chemical quality of sorghum silage. There was no effect on nutrient composition or in vitro digestibility. The effect of different variety on the nutrient value of sorghum silage was more pronounced than the wilting variable.
